I didn't know how to execute a shell command into a perl script, thx.

What's the difference between effective and non-effective, the answer are the same for
: print
"$>, $<\n" and idem for group
Moreover when I do this
print "gid: $)\n";
I get (as root) : gid: 0 10 6 4 3 2 1 0
not just 0. How to get just the true gid?

Yes I know. My first goal was to get the gid. Now I want to attribute ip address by
gid, maybe
thanks to :
if ($( == 1000)
{
qx/ifconfig eth0 x.x.x.x up/;
}
elseif ($( == 1001)
{
qx/ifconfig eth0 x.x.x.y up/;
}
