wube has asked for the wisdom of the Perl Monks concerning the following question:
Hi Monks.
How does one test whether a daemon is up and running ??
My code follows :
The snippet is in a script called " testd.pl" . The problem is that this code finds itself running and always exits. What I really want to do is to see if a previous invocation is still active ?? Any advice will me much appreciated. TIA
