in reply to Perl launching process

My Rule of Thumb:

  1. If you don't care about exit codes or output, use system().
  2. If you just want the exit code, use system().
  3. If you just want the output or error or both combined, use backticks.
  4. For anything else, use a module.

    Regarding #3, backtick does not capture stderr by default? Unless shell redirection is used?

      It does not, as a trivial test will confirm.

      $ perl -e 'print "###", `chown foo /`, "###\n"'
