in reply to Call Python script and pass arguments from Perl script

I don't recommend using the quotemeta operator. That will usually misquote newlines with POSIX-like shells.

Instead, skip the shell and use the multiple argument form pipe open, such as

my $output; { my @command = "sudo", "/usr/bin/python", "/home/processLog.py", $n +ame, $age, $text, $id; open my $P, "-|", @command or die "error pipe opening program"; local $/; $output = <$P>; close $P or die "error: spawned program exited with failure or cannot read + pipe"; # note: you may want to accept an exit failure with some programs. + if you do, check eof($P) instead to catch a read error. } print $output;

Update: added "skip the shell".
