Re: Line breaks within backticks

I would use your first method, but if you must do it in one statement you can try

use strict;
use warnings;

my $result = qx[${\ ( 
               'ls -l ' .
               '/etc'  .
               '/passwd' ) 
             }];
print $result . "\n";

output:

-rw-r--r-- 1 root root 1867 Apr 28 15:00 /etc/passwd

Excellent! Thank you. I tried similar constructs, but didn't find the "${\(...)}" combination. So what we're doing is creating a reference and then dereferencing it, right? It seems a bit backward, but... if it works, it works. And I agree, the two-step solution is probably prettier, but I'm trying to write compact code for a coding contest, so fewer lines is more important in this case.	[reply]
