Are you REALY sure you mean exec() ???
>From perldoc -f exec
exec LIST
exec PROGRAM LIST
The "exec" function executes a system command *and never
returns*-- use "system" instead of "exec" if you want it to
return. It fails and returns false only if the command does not
exist *and* it is executed directly instead of via your system's
command shell (see below).
Since it's a common mistake to use "exec" instead of "system",
Perl warns you if there is a following statement which isn't
"die", "warn", or "exit" (if "-w" is set - but you always do
that). If you *really* want to follow an "exec" with some other
statement, you can use one of these styles to avoid the warning:
I believe you could to something like
system( 'subtask &');
to start the command without waiting for it. You'll need something like
"nohup" or whatever ... I've not used unix for some time ... to make sure the
process survives your logout.
