This document is a "practical guide" to very quickly setup CVS/RCS source code
control system. This document has custom shell scripts that are wrappers on top of CVS. These scripts provide an easy user interface for CVS. Several shell scripts are provided to make RCS easier to use.
The information in this document applies to Linux and as well as to all other flavors of Unix liks Solaris, HPUX, AIX, SCO, Sinix, BSD, SCO, Apple Macintosh (which is BSD unix) etc.. and BeOS.
Introduction
(The latest version of this document is at �.
You may want to check there for changes).
A source code control system is a MUST to manage
the changes occurring to a software project during development. Developers need a complete history of changes
to backtrack to previous versions in case of any problems.
Since source code is the most vital component of any software project and
software development takes a huge amount of time and money, it is very important to spend some
time in safe-guarding the source code by using source code control systems like CVS and RCS.
CVS (Concurrent Version Control System) is a powerful tool which allows
concurrent development of software by multiple users. It uses RCS
underneath and has an application layer interface as a wrapper on top of RCS.
CVS can record the history of your files (usually,
but not always, source code). CVS only stores the differences
between versions, instead of every version of every file
you've ever created. CVS also keeps a log of who, when and
why changes occurred, among other aspects.
CVS is very helpful for managing releases and controlling
the concurrent editing of source files among multiple
authors. Instead of providing version control for a
collection of files in a single directory, CVS provides
version control for a hierarchical collection of
directories consisting of revision controlled files.
These directories and files can then be combined
to form a software release.
CVS can be used for storing "C", "C++", Java, Perl, HTML and
other files.
HISTORY of CVS:
CVS is a very highly sophisticated and complex system. It is the
"State of the Art"
technology and is so called "software miracle". The CVS software is a
very advanced and capable system developed
over a very long period of time. And it took several years to mature!!. It tooks
about 20 to 30 years of research to develop CVS algorithms and later coding it
into a software. And even today, it is still evolving!!
CVS algorithms actually started in Universities several decades ago and
CVS implementation started out as a bunch of shell scripts written by Dick Grune, who
posted it to the newsgroup comp.sources.unix in the volume 6 release
of December, 1986. While no actual code from these shell scripts is present in the
current version of CVS much of the CVS conflict resolution algorithms come from them.
In April, 1989, Brian Berliner designed and coded CVS. Jeff Polk
later helped Brian with the design of the CVS module and vendor branch support.
And today each and every major software development project in the world is written
using CVS as the safe repository. As good old software hats say -
"You are in very safe hands, if you are using CVS !!!"
Which One Is for Me? CVS or RCS
CVS actually uses RCS underneath. CVS is a lot more powerful tool and
can control a complete source code tree.
It is very strongly recommended that you use CVS, because you can greatly customize CVS with scripting languages like PERL, Korn and bash shells.
See the sample korn shell scripts at .
Advantages of CVS:
CVS is decentralised so a user checks out files/directories
from the repostitory
and have his own separate stable source directory tree.
CVS can "STAMP" releases of an entire project source tree.
CVS can enable concurrent editing of files.
CVS can be greatly customized to enable strong locking of files
via shell scripts or PERL scripts.
CVS supports weak locking with the command 'cvs watches' and also
no locking permitting concurrent editing of files.
Disadvantages of CVS:
Needs a little more administration than RCS.
Very highly sophisticated and complex system. It is "State of the Art"
technology. The cvs software is a very advanced and capable system developed
over a very long period of time (it took several years!!). It tooks about 20 to 30 years
of research to develop CVS and it is still evolving!!
Has a large number of commands and command options, hence a steeper
learning curve for beginners. The shell scripts at can ease usage.
Advantages of RCS:
RCS is very simple to setup, with less administrative work.
RCS is used in a centralized area where everyone works.
RCS is useful for simple systems.
Very strong locking of files - concurrency eliminated.
Downside of RCS:
Concurrent development by multiple developers is not possible due to file
locking and being limited to a single working directory. Because of the
single working directory limitation, changes to files by multiple developers can
cause failure of the 'make' command.
Cannot stamp releases of an entire software project.
This document also has
shell scripts which provide
simple commands to check-out, check-in, and commit files.
See shell scripts at
For RCS see the RCS mini-howto on the Linux cdrom:
cd /mnt/cdrom/Redhat/RPMS
ls -l howto-6.0-*.noarch.rpm
rpm -qpl howto-6* | grep -i rcs
or visit �
See also the RCS shell scripts at
Setting up CVS
First you need to install the CVS package. On Redhat Linux use:
cd /mnt/cdrom/Redhat/RPMS
rpm -i rcs*.rpm
rpm -i cvs*.rpm
To see the list of files installed do -
rpm -qpl cvs*.rpm | less
and browse the output using j,k, CTRL+f, CTRL+D, CTRL+B, CTRL+U or using arrow keys, page up/down keys.
See 'man less'.
On other flavors of Unix, you may need to download the RCS and CVS tar balls
and follow the README, INSTALL files to setup CVS.

and �
Environment variables
The following environment variables need to be setup in /etc/profile - default
values required for all users.
If not set in /etc/profile, then you should add these to your
local profile file /.bash_profile.
export EDITOR=/bin/vi
export CVSROOT=/home/cvsroot
export CVSREAD=yes
And of course, individual users can override the environment variables
set in /etc/profile by resetting them in their local profile file /.bash_profile
# File ~/.bash_profile
# Overriding env variables by resetting
export EDITOR=/usr/bin/emacs
export CVSROOT=/home/anotherdir/java/cvsroot
Create a directory to store the source code repository
and give read, write access to Unix group/user.
Also make sure that the directory name of CVSROOT does not contain
any blank spaces. For example CVSROOT should not be like '/home/my rootcvs'.
bash$ su - root
bash# export CVSROOT=/home/cvsroot
bash# groupadd --help
bash# groupadd cvs
bash# useradd --help
bash# useradd -g cvs -d /home/cvsroot cvs
bash# ls -ld $CVSROOT ... (you should see the listing)
bash# chgrp -R cvs $CVSROOT
bash# chmod o-rwx $CVSROOT
bash# chmod ug+rwx $CVSROOT
#To initialize the CVS repository and to put in source code files do:
bash# cvs init
# Add the unix users to the cvs group. Create supplementary groups for users.
# Note that you MUST not put any blank spaces after comma seperating the
# group names in -G option.
# In example below user tom belongs to groups cvs, users and staff and user
# johnson belongs to group cvs only.
bash# usermod --help
bash# usermod -G cvs some_unix_username
bash# usermod -G cvs,users,staff tom
bash# usermod -G cvs,users,staroffice billclinton
bash# usermod -G cvs johnson
bash# exit .... (logout of root superuser mode)
# Login as a user and import files into cvs....
bash$ su - billclinton
bash$ export EDITOR=/bin/vi
bash$ export CVSROOT=/home/cvsroot
bash$ export CVSREAD=yes
# Change directory is a must
bash$ cd $HOME/somedir/anotherdir/directory/my_source_code_dir
# Must give vendor tag and revision tag
cvs import somedir/anotherdir/directory/my_source_code_dir Vendor1_0 Rev1_0
# Also note that it is very important to give the directory tree starting
# from the $HOME, that is, in above example starting from somedir.
# For example I did:
bash$ cd $HOME/howto/foobar
bash$ cvs import howto/foobar Vendor1_0 Rev1_0
# Another example is:
bash$ cd $HOME/javafilesdir
bash$ cvs import javafilesdir Vendor1_0 Rev1_0
# A sample testing and verification:
bash$ cd $HOME/howto/foobar
bash$ cvs checkout myfoo.java
TROUBLESHOOTING: When doing checkout it says module is unknown. It
is a common mistake not to change directory while doing cvs import. You
MUST change directory to the
source-code-directory and then do cvs import. For example:
bash$ cd $HOME/somedirectory/foobardir
bash$ cvs import somedirectory/foobardir Vendor1_0 Rev1_0
Migrate RCS to CVS
To migrate the existing RCS files to CVS, use the following script. Make sure
that you installed the Korn shell package pdksh*.rpm from the Linux contrib cdrom.
NOTE : Get the Korn shell /bin/ksh by installing pdksh*.rpm from the Linux contrib cdrom
#!/bin/ksh
#############################################################
# Program to Migrate the existing source code in RCS to CVS
#
# Needs the korn shell RPM package pdksh*.rpm from Linux
# contrib cdrom
#############################################################
#
# rcs2cvs - convert source tree from RCS to CVS
#
# project to convert
PROJECT='project'
# current RCS root
RCSROOT="$HOME/rcs"
if cd "$RCSROOT/$PROJECT"
then
cd "$RCSROOT"
else
echo >&2 "`basename "$0"`: can't change to RCS directory '$RCSROOT/$PROJECT'."
exit 1
fi
# current CVS root
CVSROOT="$HOME/cvs"
# create new CVS directory for project 'project'
if mkdir "$CVSROOT/$PROJECT"
then
:
else
echo >&2 "`basename "$0"`: can't create CVS directory '$CVSROOT/$PROJECT'."
exit 2
fi
# create CVS project tree from RCS tree
find "$PROJECT" -type d -name RCS -print |
while read RCS
do
CVS="`dirname "$RCS"`"
(if cd "$RCS"
then
# if find . -type f -name '*,v' -print | cpio -pdmv "$CVSROOT/$CVS"
if find . -type f -print | cpio -pdmv "$CVSROOT/$CVS"
then
:
else
echo >&2 "`basename "$0"`: can't convert RCS subdirectory '$RCSROOT/$RCS' to CVS subdirectory '$CVSROOT/$CVS'."
fi
else
echo >&2 "`basename "$0"`: can't change to RCS subdirectory '$RCSROOT/$RCS'."
fi)
done
Now the RCS is migrated to CVS as 'project'. You can start using the
CVS commands on module 'project'.
Intro to CVS Commands
CVS provides a rich variety of commands (cvs_command in
the Synopsis), each of which often has a wealth of
options, to satisfy the many needs of source management in
distributed environments. However, you don't have to master
every detail to do useful work with CVS; in fact, five
commands are sufficient to use (and contribute to) the
source repository.
The most commonly used CVS commands are:
checkout,
update,
add,
remove,
commit and
diff.
checkout
cvs checkout modules...
A necessary preliminary for most CVS work: creates
your private copy of the source for modules (named
collections of source; you can also use a path relative
to the source repository here). You can work
with this copy without interfering with others'
work. At least one subdirectory level is always
created.
bash$ cvs --help checkout
Usage:
cvs checkout [-ANPRcflnps] [-r rev | -D date] [-d dir]
[-j rev1] [-j rev2] [-k kopt] modules...
-A Reset any sticky tags/date/kopts.
-N Don't shorten module paths if -d specified.
-P Prune empty directories.
-R Process directories recursively.
-c "cat" the module database.
-f Force a head revision match if tag/date not found.
-l Local directory only, not recursive
-n Do not run module program (if any).
-p Check out files to standard output (avoids stickiness).
-s Like -c, but include module status.
-r rev Check out revision or tag. (implies -P) (is sticky)
-D date Check out revisions as of date. (implies -P) (is sticky)
-d dir Check out into dir instead of module name.
-k kopt Use RCS kopt -k option on checkout.
-j rev Merge in changes made between current revision and rev.
(Specify the --help global option for a list of other help options)
update
cvs update
Execute this command from within your private
source directory when you wish to update your
copies of source files from changes that other
developers have made to the source in the repository.
bash$ cvs --help update
Usage: cvs update [-APdflRp] [-k kopt] [-r rev|-D date] [-j rev]
[-I ign] [-W spec] [files...]
-A Reset any sticky tags/date/kopts.
-P Prune empty directories.
-d Build directories, like checkout does.
-f Force a head revision match if tag/date not found.
-l Local directory only, no recursion.
-R Process directories recursively.
-p Send updates to standard output (avoids stickiness).
-k kopt Use RCS kopt -k option on checkout.
-r rev Update using specified revision/tag (is sticky).
-D date Set date to update from (is sticky).
-j rev Merge in changes made between current revision and rev.
-I ign More files to ignore (! to reset).
-W spec Wrappers specification line.
(Specify the --help global option for a list of other help options)
add
cvs add file...
Use this command to enroll new files in CVS records
of your working directory. The files will be added
to the repository the next time you run `cvs
commit'. Note: You should use the `cvs import'
command to bootstrap new sources into the source
repository. `cvs add' is only used for new files
to an already checked-out module.
bash$ cvs --help add
Usage: cvs add [-k rcs-kflag] [-m message] files...
-k Use "rcs-kflag" to add the file with the specified kflag.
-m Use "message" for the creation log.
(Specify the --help global option for a list of other help options)
remove
cvs remove file...
Use this command (after erasing any files listed)
to declare that you wish to eliminate files from
the repository. The removal does not affect others
until you run `cvs commit'.
bash$ cvs --help remove
Usage: cvs remove [-flR] [files...]
-f Delete the file before removing it.
-l Process this directory only (not recursive).
-R Process directories recursively.
(Specify the --help global option for a list of other help options)
commit
cvs commit file...
Use this command when you wish to ``publish'' your
changes to other developers, by incorporating them
in the source repository.
bash$ cvs --help commit
Usage: cvs commit [-nRlf] [-m msg | -F logfile] [-r rev] files...
-n Do not run the module program (if any).
-R Process directories recursively.
-l Local directory only (not recursive).
-f Force the file to be committed; disables recursion.
-F file Read the log message from file.
-m msg Log message.
-r rev Commit to this branch or trunk revision.
(Specify the --help global option for a list of other help options)
diff
cvs diff file...
Show differences between files in the working directory
and source repository, or between two revisions in the
source repository. (Does not change either repository or working directory.)
bash$ cvs --help diff
Usage: cvs diff [-lNR] [rcsdiff-options]
[[-r rev1 | -D date1] [-r rev2 | -D date2]] [files...]
-l Local directory only, not recursive
-R Process directories recursively.
-D d1 Diff revision for date against working file.
-D d2 Diff rev1/date1 against date2.
-N include diffs for added and removed files.
-r rev1 Diff revision for rev1 against working file.
-r rev2 Diff rev1/date1 against rev2.
--ifdef=arg Output diffs in ifdef format.
(consult the documentation for your diff program for rcsdiff-options.
The most popular is -c for context diffs but there are many more).
(Specify the --help global option for a list of other help options)
Emacs Editor
Emacs is a powerful editor and it supports CVS/RCS - especially
for revision merging and comparing. The main Emacs site
is at �.
Strong, Weak or No Locking
CVS is a powerful system and is highly customizable. CVS supports:
Strong locking with "reserved checkouts" via cvs admin -l or .
Also read the Reserved checkouts.
Here is a patch (�) from
Eric Griswold for reserved checkouts.
Weak locking via 'cvs watch' features.
Also see "cvs edit" to give a warning(�) if
someone else is already editing the file.
No locking - the default permitting concurrent editing of files.
Shell Scripts
The following are wrappers around the basic CVS commands. These scripts
give you initial booster-push into the CVS system and are useful
until you become very familiar with the CVS commands. The scripts
are written for Korn shell since it is always available
on all flavors of Unix, but you can translate to bash or
Perl if needed. You can customize
these scripts to your taste. They are basically CVS commands, but features are
added to make it site specific. For example, the sedit script provides locking
so that users will know someone is editing the file. Of course users can
directly use the CVS commands to bypass these scripts. These scripts
demonstrate how CVS can be customized to a great extent.
NOTE: The wrapper shell scripts assume the user's
home directory as the root and check out the tree from CVS to build the
tree underneath user's home directory.
TIP: In these shell scripts, every target filename is composed
of 3 parts - Home directory, sub-directory
and the filename. The full-path is $HOME/$subdir/$fname
And in CVS the same directory structure is maintained (by
variable $subdir) therefore in cvs there will be something
like $CVSROOT/$subdir/$fname.
In all scripts, these 4 variables $HOME, $CVSROOT, $subdir and $fname
play an important role. For example, sample values can be like
HOME=/home/aldev, subdir=myproject/src, CVSROOT=/home/cvsroot,
and fname=foo.cpp
Copy these scripts to /usr/local/bin and this should be in the user's PATH environment.
sget [-r revision_number] <file/directory name>
To get a file or entire directory from CVS in READ ONLY mode.
Click
sedit [-r revision_number] <filename>
To edit a file in order to make changes to code. This will lock the
file so that nobody else can check it out. Of course you can change the script to your requirement - make no locking, warning message, or very strong locking.
Click
scommit [-r revision_number] <filename>
To commit the changes you made to filename or entire
directory. Upload your changes to CVS.
Click
supdate <filename/directory>
To update a filename or to update an entire directory by
getting the latest files from CVS.
Click
sunlock [-r revision_number] <filename>
To unlock the file got by sedit. Will release the lock.
Click
slist
To see the list of files currently being edited by you.
Does 'ls -l | grep | ...' command.
Click .
Note that there is also another Unix
command by the name slist (list available Netware servers). You
should make sure cvs script slist comes before other in your
PATH environment.
sinfo <filename/directory>
To get the information of changes/revisions to a file.
Click
slog <filename>
To get the history of changes/revisions to a file from CVS.
Click
sdif <filename>
sdif -r rev1 -r rev2 <filename>
To get the diff of your file with CVS.
Click
NOTE: sdif has only one 'f' because there is already another
Unix command called 'sdiff'
sadd <filename>
To add a new file to CVS repository.
Click
sdelete <filename>
To delete a file from CVS repository.
Click
sfreeze <revision name> <directory name>
To freeze the code, that is make a release of the entire source tree.
Click
For example :
cd $HOME;
sfreeze REVISION_1_0 srctree
This will freeze code with tag REVISION_1_0 so that you can later
checkout the entire tree by using the revision name.

It is very strongly recommended that you use
Samba(on cdrom samba*.rpm)
and a
on MS Windows 95/NT. By using Samba the remote directory on Unix
will look like local folder on MS Windows. See the next section for
.
For Apple Macintosh - Mac OS:
See MacCvs at �
and MacCvsPro at �
CVS for MS Windows 95/98/NT/2000
It is VERY STRONGLY recommended that you use
Samba(on cdrom samba*.rpm)
and a VNC viewer (or PC X Server) on MS Windows 95/NT.
With samba the Unix/Linux CVS server will be like a file server.
By using Samba the remote directory on Unix
will look like a local folder on MS Windows on the local disk.
Install samba*.rpm on Unix/Linux server(which has the CVS repository) and install
the VNC viewer (or PC X server) on
MS Windows 95/NT/2000 desktop. Using a VNC (or PC X server) you can easily log on to the
Unix box and check-out/check-in the files. And you can use tools like
Java Visual Cafe or Java JBuilder on MS Windows to edit the files located in Unix/Linux
folder(via samba).
After editing, you can check-in the files to Unix through VNC or PC X-server.
Advantages of using CVS on Linux/Unix via MS Windows are:
Only one single Linux File server (CVS server) can serve many MS Windows clients.
A Linux file server (CVS) is very robust, secure and reliable
Only one UPS (uninterrupted power supply) battery is required for a linux server.
Linux can serve as MS Windows folder through Samba package.
A Linux file server (CVS) supports centralised backups via tools like
BRS, Arkeia, Bru
mirrors at
�,
angelfire,
geocities,
virtualave,
50megs,
theglobe,
NBCi,
Terrashare,
Fortunecity,
Freewebsites,
Tripod,
Spree,
Escalix,
Httpcity,
Freeservers.
A Linux file server (CVS) requires just one small server room which can air-contitioned
and dust free. Small room keeps the cooling/heating costs down.
A Linux file server (CVS) provides security via Unix groups and user id authentication
The best tool for remote access is VNC. The VNC is lightweight and is
much better than the PC X servers. The VNC is very strongly recommended
over PC X server. The remote access methods available are:
VNC (Virtual Network Computing) at �
VNC is not an X-server but can display the remote Unix on Windows.
VNC is the best tool in the market for remote access, it is very lightweight and
is a very powerful software.
Get VNC rpms from rpmfind.
The best Window manager for VNC is QVWM which is like MS Windows 98/NT/2000 interface, get
it from �.
After starting vncserver, you can start the vncviewer program on clients
like MS Windows, Mac or Linux.
See also the
List of X11 Windows Managers.
Compiling qvwm on Solaris :
On Solaris you should install the following packages which you can get
from � - xpm, imlib, jpeg, libungif, giflib, libpng, tiff.
And you can download the binary package for solaris from
�.
Or you can download the qvwm source for solaris from
� and compile it using gcc.
Troubleshooting compile:
You should put unsigned long before arg in usleep()

Windows 95/NT/2000 FTP Tools
You can also use the ftp tools on MS Windows to transfer files from a Unix/Linux (CVS repository)
to windows:
Go to Tucows and search "ftp tools" for MS Windows �
Visual Cafe(Java), JBuilder, MS Visual C++, HTML files
Using Samba and a PC X server it is possible to use CVS on MS Windows platform.
And the tools like Symantec Visual Cafe (Java), Inprise JBuilder, MS Visual C++
and others are easily supported by CVS.
You can also store the HTML files on a CVS repository via Samba and easily
access them from MS Windows.
Samba Admin tool
To administer samba use the admin tools from �. Go here
and click on "GUI Interfaces Tools".
Security of CVS Repository
To make a CVS server and CVS repository secure do the following:
Run CVS on a stand-alone Linux/Unix box,
see .
Remove unnecessary software packages from CVS linux box - to prevent
external vandals running it. Just in case vandals break into the system, you
do not want to give them a chance to run dangerous programs.
Consider SSH as given in the chapter
Consider Kerberos - install cvs-*-kerberos*.rpm package �.
Visit � and post your security questions in the
mailing list.
Multi-User CVS Remote Repository
The Cederqvist manual at
�
describes how to setup CVS for external access.
In order to use CVS for a group, one has to set up a permissions
system to allow people to access the system from other machines.
There are three ways to do this (:server:, :pserver:, and :ext:).
The pserver mechanism and use of rsh are
both insecure. Only the :ext: (with ssh) offers sufficient security
protection.
If you set CVS_RSH to SSH or some other rsh replacement,
the instructions may be similar to `.rhosts' but
consult the documentation for your rsh replacement.
To get ssh visit
� and in the search box enter "ssh".
Or visit � and in the search box enter "ssh".
Download and install the ssh RPM and then configure CVS to use it.
See also �.
Note: If you plan to configure CVS for use with rsh then
you MUST do this critical step:
bash# chmod 600 .rhosts
See also JA-SIG UPortal CVS repository �.
RCS Shell Scripts
If you want to use RCS instead of CVS then you can use the following
shell scripts.
cotree.sh
#!/bin/ksh
# cotree.sh (Check Out Tree shell script)
# cotree.sh - Check out the entire RCS directory
# Usage :
# This will get the all the directories
# unix> cotree.sh
#
# This will get just one single directory tree
# unix> cotree.sh <directory name>
# See also cofiles.sh

Performance Tuning of a CVS Server
For optimum performance a CVS server must be running on a stand alone Linux/Unix box.
To get more bang for a given CPU processing power, do the following:
Recompile the Linux kernel to make it small and lean. Remove items
which are not used. See the kernel
howto at �
Turn off unneccessary Unix processes - on Linux/Unix systems run chkconfig.
bash$ su - root
bash# man chkconfig
bash# chkconfig --help
bash# chkconfig --list | grep on | less
From the above list, turn off the processes you do not want to start automatically -
bash# chkconfig --level 0123456 <service name> off
Next time when the machine is booted these services will not be started.
Now, shutdown the services manually which you just turned off.
bash# cd /etc/rc.d/init.d
bash# ./<service name> stop
Do not run any other application processes which are unnecessary.
Do not leave X Window running unattended because its processes
consume memory and contribute to CPU load. It can also be a serious
security hole from outside attacks.
The X Window managers generally used are KDE, GNOME, CDE, XDM and others.
You must exit the X Window immediately after using and most of the time
you should see a command line console login prompt on the CVS server machine.
Problem Reporting System
Along with CVS, you may want to use project tracking system or problem
reporting system. Every software project needs a problem reporting system
that track bugs and assigns them to various developers.
See GNU gpl GNATS at �
and
�
And commercial PRS at �
look for a project tracking system.
Configuration Management System Tools
What is Configuration Management (CM) ?
There are a number of different interpretations.
It is about the tracking and
control of software development and its activities. That is, it concerns the
mangement of software development projects with
respect to issues such as multiple developers working on the
same code at the same time, targeting multiple
platforms, supporting multiple versions, and controlling the
status of code (for example a beta test versus a real release).
Even within that scope there are different schools of thought:
Traditional Configuration Management - checkin/checkout control
of sources (and sometimes binaries) and the
ability to perform builds (or compiles) of the entities. Other
functions may be included as well.
Process Management - control of the software development
activities. For example, it might check to ensure
that a change request existed and had been approved for fixing
and that the associated design, documentation,
and review activities have been completed before allowing the
code to be "checked in" again.
While process management and control are necessary for a
repeatable, optimized development process, a solid
configuration management foundation for that process is essential.

CSSC (SCCS like system)

SCCS for Linux �
SCCS v/s CVS-RCS
SCCS (Source Code Control System)
is no longer being enhanced or improved.
The general consensus has been that this tool is clumsy and not
suited to large numbers of users working on one project.
Actually, SCCS interleaves
all the versions, but it can make new development get
progressively slower. Hence, SCCS is NOT recommended for
new projects; however, it is still there to support old code base in SCCS.
RCS (Revision Control System) is often considered to be
better than SCCS. One reason for this is that RCS baselines the most
recent version and keeps deltas for earlier ones, making new
development faster. Additional discussions concerning SCCS vs RCS
are at �
Note that RCS learned from the mistakes of SCCS...
CVS, which requires RCS, extends RCS
to control concurrent editing of sources by several users
working on releases built from a hierarchical set of
directories. "RCS is [analogous to using] assembly language, while CVS is
[like using] Pascal".
Other Formats of this Document
This document is published in 14 different formats namely: DVI, Postscript,
Latex, Adobe Acrobat PDF,
LyX, GNU-info, HTML, RTF(Rich Text Format), Plain-text, Unix man pages, single
HTML file, SGML (Linuxdoc format), SGML (Docbook format), and MS WinHelp format.
This howto document is located at:
� and click on HOWTOs and search
for the howto document name using CTRL+f or ALT+f within the web-browser.
You can also find this document at the following mirrors sites:

select a site and go to directory /LDP/HOWTO/xxxxx-HOWTO.html
You can get this HOWTO document as a single file tar ball in HTML, DVI,
Postscript or SGML formats from -
�
and �
Plain text format is in: �
and �
Single HTML file format is in:
�
A single HTML file can be created with the command (see man sgml2html) -
sgml2html -split 0 xxxxhowto.sgml
Translations to other languages like French, German, Spanish,
Chinese, and Japanese are in
�
and �
Any help from you to translate to other languages is welcome.
The document is written using a tool called "SGML-Tools" which can be got from:
�
Compiling the source you will get the following commands like:
sgml2html xxxxhowto.sgml (to generate html file)
sgml2html -split 0 xxxxhowto.sgml (to generate a single page html file)
sgml2rtf xxxxhowto.sgml (to generate RTF file)
sgml2latex xxxxhowto.sgml (to generate latex file)
Acrobat PDF format
A PDF file can be generated from postscript file using
either acrobat distill or Ghostscript.
And a postscript file is generated
from DVI which in turn is generated from a LaTex file.
You can download distill software from �. Given below
is a sample session:
bash$ man sgml2latex
bash$ sgml2latex filename.sgml
bash$ man dvips
bash$ dvips -o filename.ps filename.dvi
bash$ distill filename.ps
bash$ man ghostscript
bash$ man ps2pdf
bash$ ps2pdf input.ps output.pdf
bash$ acroread output.pdf &
Or you can use the Ghostscript command ps2pdf.
ps2pdf is a work-alike for nearly all the functionality of
Adobe's Acrobat Distiller product: it
converts PostScript files to Portable Document Format (PDF) files.
ps2pdf is implemented as a very small command script
(batch file) that invokes Ghostscript, selecting a special "output device"
called pdfwrite. In order to use ps2pdf, the pdfwrite
device must be included in the makefile when Ghostscript was compiled;
see the documentation on building Ghostscript for details.
Convert Linuxdoc to Docbook format
This document is written in linuxdoc SGML format. The Docbook SGML format
supercedes the linuxdoc format and has a lot more features than linuxdoc.
The linuxdoc is very simple and easy to use. To convert linuxdoc SGML
file to Docbook SGML use the program ld2db.sh and some Perl scripts.
The ld2db output is not 100% clean and you need to use the clean_ld2db.pl
Perl script. You may need to manually correct a few lines in the document.
Download the ld2db program from �
or from Milkyway Galaxy site
click on "Source code for C++ howto".
Download the cleanup_ld2db.pl perl script from
from Milkyway Galaxy site
click on "Source code for C++ howto".
The ld2db.sh is not 100% clean, so you will get some errors when you run it.
bash$ ld2db.sh file-linuxdoc.sgml db.sgml
bash$ cleanup.pl db.sgml > db_clean.sgml
bash$ gvim db_clean.sgml
bash$ docbook2html db.sgml
And you may have to manually edit some of the minor errors after
running the Perl script. For example you may need to put closing tag <
/Para> for each <
Listitem>
Convert to MS WinHelp format
You can convert the SGML howto document to a Microsoft Windows Help file,
First convert the sgml to html using:
bash$ sgml2html xxxxhowto.sgml (to generate html file)
bash$ sgml2html -split 0 xxxxhowto.sgml (to generate a single page html file)
Then use the tool HtmlToHlp.
You can also use sgml2rtf and then use the RTF files for generating winhelp files.
Reading various formats
In order to view the document in dvi format, use the xdvi program. The xdvi
program is located in tetex-xdvi*.rpm package in Redhat Linux which can be
located through ControlPanel | Applications | Publishing | TeX menu buttons.
To read a dvi document give the command:
xdvi -geometry 80x90 howto.dvi
man xdvi
And resize the window with the mouse.
To navigate use Arrow keys, Page Up, Page Down keys, also
you can use 'f', 'd', 'u', 'c', 'l', 'r', 'p', 'n' letter
keys to move up, down, center, next page, previous page etc.
To turn off expert menu press 'x'.
You can read a postscript file using the program 'gv' (ghostview) or
'ghostscript'.
The ghostscript program is in the ghostscript*.rpm package and the gv
program is in the gv*.rpm package in Redhat Linux
which can be located through ControlPanel | Applications | Graphics menu
buttons. The gv program is much more user friendly than ghostscript.
Also ghostscript and gv are available on other platforms like OS/2,
Windows 95 and NT. You can view this document even on those platforms.
Get ghostscript for Windows 95, OS/2, and for
all OSes from �
To read a postscript document give the command:
gv howto.ps
ghostscript howto.ps
You can read an HTML format document using Netscape Navigator, Microsoft Internet
explorer, Redhat Baron Web browser or any of the 10 other web browsers.
You can read the latex, LyX output using LyX an X Window front end to LaTex.
