in reply to Assigning output of unix command to a variable

#!/usr/bin/perl use strict; my $node = qx( nslookup www.perlmonks.org | awk -F Name: '{ print \$2 }' ); print $node;

[LanX]: what are temps?
[moritz]: oh, the question was about creation, not indexing
[thepkd]: temporary variables
[moritz]: [ { a => [ { b => 1 } ] } ]
[choroba]: dereference ne creation
[choroba]: at least in my lingo
[moritz]: .oO( oh temps, oh moritz )
