Re: ^M Characters - files in dos format

[Frederic Brehm]

Lots and lots of people keep asking:

> files in dos format during check-in.

and I'm tired of it. So, here's the solution....

The script pasted below should do the trick. I cut it down from a larger 
one that has more options, so try it first. The comments should tell you 
what's going on.

I would be very happy if someone could put this into the CVS FAQ, the CVS 
contrib directory, and anywhere else that people who are looking for this 
solution can find it.

# SUMMARY
#
# cvs-no-cr
#
# A cvs commitinfo script to prevent files containing
# carriage return characters from getting into the
# repository. This script may not work for files
# with spaces in their names without modification.

# AUTHOR
#
# Frederic W. Brehm, address@hidden

# COPYRIGHT
#
# None claimed. This script is free to use as you see fit.

# INSTALLATION
#
# 1. Replace the ^M in the grep command below with a real carriage return.
# 2. Change the error message to meet your local conventions.
# 3. Put this script into $CVSROOT/CVSROOT.

# USAGE
#
# Suppose you want to prevent all *.c and *.h files in module "A"
# from being checked if they contain a carrage return. Put the following
# line in commitinfo (without the leading "#", of course).
#
#       A       $CVSROOT/CVSROOT/cvs-no-cr \.h$,\.c$
