NAME

Perl::Review::Policy::InputOutput::ProhibitBacktickOperators

DESCRIPTION

Backticks are super-convenient, especially for CGI programs, but I find that they make a lot of noise by filling up STDERR with messages when they fail. I think its better to use IPC::Open3 to trap all the output and let the application decide what to do with it.

use IPC::Open3;

@output = `some_command`;                      #not ok

my ($writer, $reader, $err);
open3($writer, $reader, $err, 'some_command'); #ok;
@output = <$reader>;  #Output here
@errors = <$err>;     #Errors here, instead of the console

NOTES

This policy also prohibits the generalized form of backticks seen as qx{}.
