Hello,

I tried to do a small perl script to check if amule is running and if it's not to launch it, but that's not working...
I never ever programmed in perl before, it must be a dumb error, but I can't find it :(

any idea?

#!/usr/bin/perl

$cmd="ps -A | grep amule | grep -v grep";

$output=qx/$cmd/;

if ($output!=~m/$amule/) {

qx/amule/;

}

could you help us out by letting us know what kind of error you are getting when you try to run the program that will help a lot, thanks :)

Basically, it gives no error but does nothing

I am kind of sure that the problem come from the 2 first lines...

$cmd="ps -A | grep amule | grep -v grep";

$output=qx/$cmd/;

cos if I try only that in the script, it only takes the ps -A part, as if it cut aftyer the |

The problem is that $output!=~m/$amule/ is not correct ... instead of !=~ you should have used !~ ... so: $output !~ m/$amule/
