 Posted: Wed Oct 02, 2002 3:13 pm Post subject: perl script question |
 |
|
Hello,
I wrote a quick perl script to automatically start ripping from icecast/smartcast servers given as .pls files (playlist) with http:// ressources.
My question is how can I detach streamripper from the perl script. That is in my foreach loop, I have something like`streamripper $line &` but it does not detach... Any ideas?
I am thinking of thread programming but that's overkill. ALso I could hack streamripper to have it automatically detach when iI pass it -d, but I am lazy..
Thanks!!

Can you do something like: | Code: | unless( fork ) {
exec( "streamripper", $line );
} |
The perlipc man page has some examples of fork/exec. You may need to redirect STDOUT and STDERR to /dev/null, as described in the section "Complete Dissociation of Child from Parent".

You may need a handler for $SIG{CHLD}. Also, check out POSIX::setsid().
