I have a small perl script in my $CVSROOT/CVSROOT directory that goes
like this:
#!/usr/bin/perl
# This script is a small tool that can be used to update $CVSROOT/passwd
# files, by ommiting pairs of username:password (with password being the
# encrypted form of the second command line argument.
#
# $Id: cvspasswd.pl,v 1.1 2000/07/02 23:28:10 charon Exp $
&usage unless (defined($user = $ARGV[0]));
&usage unless (defined($pass = $ARGV[1]));
$salt = join '', ('.', '/', 0..9, 'A'..'Z',
'a'..'z')[rand 64, rand 64];
$crypted = crypt($pass, $salt);
print "$user:$crypted:cvs\n";
sub usage {
die "usage: cvspasswd USER PASS\n";
}
With this script, I can write something like:
% perl cvspasswd.pl username password >> ~cvs/CVSROOT/passwd
and have the password added for a new user in CVSROOT/passwd. Of
course, if the user already exists in CVSROOT/passwd or you don't want
to give everyone the same rights as user `cvs' while they're using
cvs's :pserver: access method, you might have to edit manually
CVSROOT/passwd after this is done.
