postfix-collate(1)

✨ NAME ✨

postfix-collate β€” the little script that untangles your Postfix logfile for you πŸ’–


πŸ¦‹ DESCRIPTION πŸ¦‹

Okay bestie, so picture this: your Postfix log is a whole mess of interleaved lines and it's giving chaos. This script β€” written by Viktor Dukhovni, king behavior honestly πŸ‘‘ β€” untangles that logfile and groups the records one "session" at a time, figuring out which lines belong together based on queue ID and process ID information. No cap.

It lives at auxiliary/collate/collate.pl in the source tree, in case you wanted to go read it and feel something 🫢

Records from different sessions get separated by an empty line ✨ Which is lowkey the best part, because that means the output is stupid easy to process downstream:

  • in perl, just set $/="" πŸ”₯
  • in awk, just set RS="" πŸ”₯

Paragraph mode, periodt. That's the whole vibe.


πŸ’… USAGE πŸ’…

postfix-collate file...

You hand it files, it collates them, you live your life 🌸

And when you don't specify any file at all? It reads from standard input instead, because of course it does, main character energy. Feed it a pipe, feed it a redirect, it's not picky πŸ’œ


fr fr, that's the entire page β€” tiny script, huge slay. Go forth and collate πŸ¦‹
