SAVE A COPY

Ever edited a file, then wished 
you'd saved a copy first?

This script will save it for you. 
It even handles multiple files, 
and multiple edits of the same file.

############### Cut here ##########
#!/bin/ksh
# My vi : Save a backup of the file(s) to edit
for file in $* ; do
   if [[ -a $file ]] ; then
      basefile=`basename $file`
      cp $file ~/bak/${basefile}.`date +%C%y%m%d%H%M%S`
   fi
done
/usr/bin/vi $*
############### Cut here ##########

You'll need to create a directory 
called 'bak' in your $HOME directory, 
and it would be a good idea to set up 
a cron job to clear out old copies 
periodically.
