prevent users to run the same script at the same time, on the same machine
 
Hello All,

Is there any way to prevent users to run the same script at the same time, on the same machine?

Thanks

Create a directory in /tmp; if you cannot create the directory,
someone else is already using the script.

Be sure to remove the directory when the script exits:

Code:
mkdir /tmp/${0##*/}-running 2>/dev/null || {
  echo script already running
  exit
}
trap 'rmdir /tmp/${0##*/}-running' EXIT

Thank you very much , Will this cover the case that the user hits Crtl-C?
