$$ or $PID See perlvar for details. (Note that `$PID` is only available if you `use English;`)	[reply] [d/l]

And if you're wondering where to grab $PID from, take a look at the English module.	[reply]

run the system("ps > t") command from the perl script and do a string search for the particular PID required Originally posted as a Categorized Answer.	[reply]

With respect to Anonymous Monk's response: $$ works just fine on my Win32 machine, but $PID fails when use strict is enforced. It fails with the error message: `Global symbol "$PID" requires explicit package name at MyNewTest05.pl +line 6. Execution of MyNewTest05.pl aborted due to compilation errors.` [download] That signals to me that $PID is not being set as one of the special Perl variables...at least on my machine. So the OP may need to see which one (if any) of Anonyous Monk's suggested alternatives works for the OP.	[reply] [d/l]

If you've read perlvar you would know $PID is only available when you use English;	[reply]
