Limiting "sudo kill" to killing only user processes

[Dennis Handly]

>Is there a way to restrict the input to accept only numerical entries and no wildcards?

The script has no idea if there were wildcards but it can validate the input.

You could use pattern matching to check:

if [[ "$pid" != [0-9][0-9]* ]]; then

   echo "Invalid PID: $pid"

   continue

fi

And you can optimize the pattern match with:

if [[ "$pid" != +([0-9]) ]]; then

>The comparison != is for strings, while -ne is for numbers.

Right.  If you like != so much, you can always use:

(( $? != 0 ))

Thank you all very much for your help. The script looks and runs beautifully. I'm sure someone else will find this useful as well. Much appreciation and respect gentlemen!!!
