I have looked for the discussion on how to prevent a client from
execution a program multiple times. ( I think it was on this list )
I was unable to find it so I wrote the following bash script
and plan to put it into /usr/sbin/noprogdup.sh . Please
critique/discuss the script to help me improve it so that
I will be able to prevent 16 young clients from starting 55
instances of TuxPaint and other programs.
---------cut------------
#!/bin/bash
prog=$1
myline=$*
# check for some input if $prog is not empty
if [ ! -z $prog ]
then
targ=`ps -U $USER | grep $prog | awk '{print $4}'`
if [ -z $targ ]
then
eval $myline
fi ## -z $targ
fi ## -z $prog
---------end-cut--------
TIA
