Hi.

A demo script that creates a file, checks it in, modifies it, check in changes:

Code:

#!/usr/bin/env bash

# @(#) s1	Demonstrate non-interactive rcs check-in.

# Utility functions: print-as-echo, print-line-with-visual-space.
pe() { for i;do printf "%s" "$i";done; printf "\n"; }
pl() { pe;pe "-----" ;pe "$*"; }

# Remove debris from previous attempts, create new RCS.
pl " Contents of new directory RCS:"
rm -rf RCS
mkdir RCS
ls -lgG RCS

# Create a data file.
pe ' Hello, world. ($Revision$)' > hi.txt
pl " Contents of text file:"
cat hi.txt

# Check in file.
pl " Contents of checked-in file:"
ci -l -t"-Original" hi.txt
cat hi.txt

# Check directory.
pl " Contents of RCS/:"
ls -lgG RCS

# Modify file in place, check in changes:"
pl " Modify file, check in changes:"
sed -i 's/world/universe/' hi.txt
ci -l -m"Next" hi.txt

pl " Contents of new file:"
cat hi.txt

exit 0

producing:

Code:

% ./s1

-----
 Contents of new directory RCS:
total 0

-----
 Contents of text file:
 Hello, world. ($Revision$)

-----
 Contents of checked-in file:
RCS/hi.txt,v  <--  hi.txt
initial revision: 1.1
done
 Hello, world. ($Revision: 1.1 $)

-----
 Contents of RCS/:
total 4
-r--r--r-- 1 230 Feb 25 16:16 hi.txt,v

-----
 Modify file, check in changes:
RCS/hi.txt,v  <--  hi.txt
new revision: 1.2; previous revision: 1.1
done

-----
 Contents of new file:
 Hello, universe. ($Revision: 1.2 $)

See man ci for details ... cheers, drl

Well it is not a bad idea. I have worked for one place that did that. It wasn't my idea but I did not object. The reason it is done is to put critical files like nsswitch.conf, hosts, and so on under RCS control. Previous versions are then available to see how stuff changed over the years. ...

rcsfreeze

RCSFREEZE(1)						      General Commands Manual						      RCSFREEZE(1)

NAME

       rcsfreeze - freeze a configuration of sources checked in under RCS

SYNOPSIS

       rcsfreeze [name]

DESCRIPTION

       rcsfreeze assigns a symbolic revision number to a set of RCS files that form a valid configuration.

       The  idea is to run rcsfreeze each time a new version is checked in.  A unique symbolic name (C_number, where number is increased each time
       rcsfreeze is run) is then assigned to the most recent revision of each RCS file of the main trunk.

       An optional name argument to rcsfreeze gives a symbolic name to the configuration.  The unique identifier is still generated and is  listed
       in the log file but it will not appear as part of the symbolic revision name in the actual RCS files.

       A log message is requested from the user for future reference.

       The  shell  script  works  only on all RCS files at one time.  All changed files must be checked in already.  Run rcsclean(1) first and see
       whether any sources remain in the current directory.

FILES

       RCS/.rcsfreeze.ver
	      version number

       RCS/.rcsfreeze.log
	      log messages, most recent first

SEE ALSO

       co(1), rcs(1), rcsclean(1), rlog(1)

BUGS

       rcsfreeze does not check whether any sources are checked out and modified.

       Although both source file names and RCS file names are accepted, they are not paired as usual with RCS commands.

       Error checking is rudimentary.

       rcsfreeze is just an optional example shell script, and should not be taken too seriously.  See CVS for a more complete solution.
