Wrap the part that errors with eval

eval
{
open (FILE, "somefile.that.doesnot.exist");
close(FILE)
};

Hi Antonio,

You can create a cron script which checks regular whether the script is
died, if it has then restart it.

Alternatively you can fork the process and catch the return from the child
process.

I would suggest the first, which would require no change in the current code
you have, just need to write a small script for cron.

Take care,
Paul Alapatt
