S6-FDHOLDER-LIST(8)

📦 version 2.15.1.0, in nixpkgs unstable

🌈 s6-fdholder-list(8) — your fave fd-list bestie from the System Manager's Manual 🦋

💖 NAME 💖

s6-fdholder-list — lists the file descriptors that s6-fdholderd(8) is holding onto right now 💅

✨ SYNOPSIS ✨

s6-fdholder-list [-t timeout] path

🎀 DESCRIPTION 🎀

okay so s6-fdholder-list connects to an s6-fdholderd(8) server process that's listening on path.

Then she gets the list of identifiers corresponding to the file descriptors that are currently held. She prints this list to stdout, one identifier per line — literally one per line, no cap 🌸

💅 OPTIONS 💅

  • -t timeout — if the operation can't be processed in timeout milliseconds, then she fails with an error message. Communications with the server should be near-instant, so this option is only here to protect users against programming errors (connecting to the wrong socket, for instance). iykyk 🫶

⭐ EXIT STATUS ⭐

  • 0 — success, slay 💖
  • 1 — the server denied the operation. The meanings of the error messages are explained in s6-fdholder-error-codes(7).
  • 100 — wrong usage 🙈
  • 111 — system call failed — this includes attempting to connect to a nonexistent socket, or one where no s6-fdholderd(8) daemon is listening 💀
