Perl equivalent of shell for &

listener · 03-26-2010, 10:26 AM

I wrote a spinner in Perl and when I did a spinner in shell I could just run the subroutine in the background.

my_spinner &;
PID=$!;
#do something here
my_spinner_stop $PID;

In Perl, how do you run a function in a background and get the PID for that? I know PID in Perl is $$

thanks,
listener
