Try this:
$ cat ~/bin/stamp
#!/bin/bash
#
# stamp is a utility which makes a backup of a conf file
[ $# -ne 1 ] && echo "usage: `basename $0` filename" && exit 100
old="$1"
new="$1.`date +%Y%m%d`.$$"
[ ! -f $old ] && echo "$old does not exist" && exit 100
cp $old $new
status=$?
[ -x $new ] && chmod -x $new
exit $status
$
It's crude, but it works well enough.
$ cd /etc/httpd
$ sudo stamp httpd.conf
# I get a file like "httpd.conf.20050311.15629".
$ vim httpd.conf && apachectl configtest
# I make a royal mess of things. Damn.
$ cp httpd.conf.20050311.15629 httpd.conf
$ apachectl configtest
# All is right with the world again.
Something like CVS / SVN / BitKeeper would be "better", but not easier.
