in thread Using IPC::Open3 instead of backtick operator

Depending on configuration, IPC::Cmd will use either IPC::Run or IPC:Open3, so will capture STDERR as well as STDOUT.

Called with 1 buffer, IPC::Cmd will put both STDOUT and STDERR in that buffer. Called in list context, it will return seperate buffers for STDOUT and STDERR.

    use strict;
use warnings;
use IPC::Cmd qw( run );

my $tool = 'tar';
my $cmd = [ 'perl', '-e', 'warn "TEST FAILED IF YOU SEE THIS\n"' ];
my $buffer = '';
my @out = run( command => $cmd,
          buffer => \$buffer,
          verbose => 1 );

    $ perl z.pl
Running [perl -e warn "TEST FAILED IF YOU SEE THIS\n"]...
TEST FAILED IF YOU SEE THIS

    However, one simply has to remove verbose => 1 to make this a solution.
