Modify IO layers used by backticks

Question

i.e. being able to do

$result = `my command`;

using :raw, :utf8, etc.

Any special variables I don't know about, alternative methods or modules that can be used?

Answer 1

Well I don't know if there are any special variables, but why not use open() for that task? You can specify the encoding on pipes like you would on files:

open(my $cmdin, "-|:raw", "your command");
my $result = join('', <$cmdin>);
close($cmdin);

Answer 2

Use popen:

open (my $fd, "-|", $prog, @args) 
    or die "Couldn't start $prog: $!";
do_whatever($fd);
while (<$fd>) { ... };

Or if that's not enough you should look at IPC::Open2 and its cousin Open3.
