in thread how can a perl script determine it's own PID while running

Though if your script gets severely trashed a la kill -9 the file would still be there. Usually you are best off combining the pid file with a kill check... or a check for the proc dir.

    That's why you don't just check for the file. If the file exists, you read the process's pid from the file and then check for the process.
