[K12OSN] Push Icon to desktop problem

[Petre Scheie]

Note that there's a typo in the original script: the first line should begin with #! not 
!#  -- sometimes referred to as 'sh-bang' to make it easy to remember ("Scripts always 
start with a sh-bang!").  With that out of the way, how about this for incorporating 
Kevin's suggestion:

#!/bin/bash
for y in $@; do
   for x in `ls /home`; do
     echo "Removing $y from $x..."
     rm -f /home/${x}/${y}
     if [ $? != 0 ]; then
       echo "There was a problem removing /home/${x}/${y}"
     fi
   done
done

I changed the two step process of changing into the user's directory and deleting the 
file into a single step of deleting the file by specifying the full path.  Years ago, I 
had a system that stopped responding one day.  When we looked into it we found that 
major portions of the system files were just gone.  After about 22 hours of scratching 
our heads, we restored the system from tape.  Shortly after we finished restoring, in 
the middle of the afternoon, the system again stopped responding, and investigation 
found major portions of the system files missing.  Turned out we had a cron job that ran 
at 1pm every day that found some temp files older than two days and removed them.  The 
script looked something like this:

cd /other_logs
find . -mtime +2 -exec rm {}\;

Guess what happens when someone removes the /other_logs directory because the process 
that put files in that directory is no longer used (but isn't aware of this cronjob)?!
