Question

I would like my script to remove itself automatically since its work is done. I have added the line below to the end of my script:

unlink($0);

For some reasons, it’s not working. Could you please advise what I should do? Probably, there is another approach or I could add an error message to find out why it’s not removed?

Thank you.

I don’t know why you can’t. It works in my machine. Maybe your file system locks the file when it’s running.

And you please try this:

exec "rm -f '$0'";

which replace the current Perl process with the rm one. This should release your script and has it removed.
