Do you want to "pause" the 2nd invocation of your script if an earlier invocation is still running, or do you want to exit? If you're running a script every 5 minutes that takes more than 5 minutes to run, it would seem that pausing could lead to a large backlog of paused scripts at the end of the day.

You can use ps and grep -c to count the number of times a script is running, but note that you might never reach the condition to escape the paused mode if you ever get to the point where you have one active and two paused copies of your scripts.

You can use a lock file to guarantee that only one script is running at a time. But, if you have more than one paused script, there is no way to specify that multiple paused scripts will acquire the lock in the same order in which the paused processes originally started (if that matters). You could add logic to your code to enforce an execution order if that matters to you.

Both of the above suggestions have been discussed in several threads in this forum before.

DESCRIPTION
