Reading output from command into Perl array

Question

I want to get the output of a command into an array — like this:

my @output = `$cmd`;

but it seems that the output from the command

Answer 1

This simple script works for me:

#!/usr/bin/env perl
use strict;
use warnings;

my $cmd = "ls";    
my @output = `$cmd`;    
chomp @output;

foreach my $line (@output)
{
    print "<<$line>>\n";
}

It produced the output (except for the triple dots):

$ perl xx.pl
<>
<>
<>
<>
<>
...
<>
<>
<>
<>
<>
$

The output of command is split on line boundaries (by default, in list context). The chomp deletes the newlines in the array elements.
