I'm new to this scripting. your help is greatly appreciate.

Date: Wed, 09 Nov 2005 15:35:02 -0700 Off the top of my head this would be a simple bash script that would call the app. Could look like this. This is my quick idea. I have not tested it. Could use some work. ===== START BASH SCRIPT ===== #!/bin/bash OUR_PID=$$ # Get the basename of the program to run APP_NAME=$0 NANE_LENGTH=${#APP_NAME} SHORT_NAME_LENGTH=`expr $NANE_LENGTH - 4` CALLED_APP_NAME=`echo "$0" | cut -b -$SHORT_NAM E_LENGTH` # Use a PID lock file to see if it is already running LOCK_FILE="$HOME/tmp/${CALLED_APP_NAME}.lock LOCK_PID=0 if [ -f $LOCK_FILE ]; then LOCK_PID=`< $LOCK_FILE` fi if [ $LOCK_PID -gt 0 ]; then # It was run before, we have a PID but it could be an old PID # See if that program is still running by this user, match the PID, the program name and the user STILL_RUNNING=`ps -p $LOCK_PID -u | grep ^$USER | grep $CALLED_APP_NAME` # Something returned means it is still running if [ ! "$STILL_RUNNING" = "" ]; then exit 0 fi # Nothing returned means it is an old PID fi # Put our PID into the file to stop this script from running twice # This is fast because the program we call could be slow to start up echo -n "$OUR_PID" > $LOCK_FILE # Call the app and give it any passed argument, get the PID and put it into the lock file $CALLED_APP_NAME $@ & CALLED_PID=$! echo -n "$CALLED_PID" > $LOCK_FILE exit 0 ===== START BASH SCRIPT ===== Then use this script as a wrapper for the program. If your program is mozilla in /usr/bin/mozilla make the bash script /usr/bin/mozilla.bsh If you have a lot of programs you want to wrap use sym links. Save the script as /usr/bin/RunOnlyOnce.bsh ln -s /usr/bin/RunOnlyOnce.bsh /usr/bin/mozilla.bsh ln -s /usr/bin/RunOnlyOnce.bsh /usr/bin/gedit.bsh ln -s /usr/bin/RunOnlyOnce.bsh /usr/bin/kmail.bsh ln -s /usr/bin/RunOnlyOnce.bsh /usr/bin/someprogram.bsh On Wed, 2005-11-09 at 03:24 -0800, Jhommer Oblego wrote: > Hello, > Just want to ask if there is a program or script that > limits the applications to only runonce specially on > clicking on desktop icon? > > I having problem on users doing multiple click on > desktop icon or program menu and results to multiple > program execution which slowdown the server and > sometimes hang the server. > > do you have any suggestions on how to address this problem?
