in reply to system, pipes, shell, quoting

Simpliest solution: break dependacy on shell. Just don't use it: replace system with IPC::Run and you don't need to call shell to pipe output from one program to another anymore.

use IPC::Run qw(run);

run([$program1, $file1], '|',
    [$program2, '-x', '-y'], '|',
    [$program3], ">$file2", '2>/dev/null')
    or die "Error: $?";

    ooooh :-)

    This is exactly was I was looking for, thanks very much!

    Does IPC::Run "come with perl" ?
