✨ MU-HELP(1) ✨

okay bestie, welcome to the mu help manual page, straight out of section 1 of the General Commands Manual 💅 grab a snack, we're learning how to ask mu for help.

🌸 NAME 🌸

mu-help — show help information about mu commands. that's it, that's the whole job, and she does it flawlessly ✨

🎀 SYNOPSIS 🎀

mu [COMMON-OPTIONS] help [COMMAND]

🦋 DESCRIPTION 🦋

mu help provides help information about mu commands. literally, it's the "hey bestie what does this do" command 🫶 you ask, she answers, no drama.

💖 COMMON OPTIONS 💖

these are the shared options, the ride-or-dies that show up for every mu command 🫶

  • -d, --debug — makes mu generate extra debug information, which is useful for debugging the program itself. that debug info goes to the standard logging location; peep mu(1) for the deets.
  • -q, --quiet — makes mu not output informational messages and progress information to standard output, sending them only to the log file. error messages will still be sent to standard error, so don't worry, you'll still hear the bad news 😭 note that mu index is much faster with --quiet, so it is recommended you use this option when using mu from scripts etc. yes queen, speed.
  • --log-stderr — causes mu to not output log messages to standard error, in addition to sending them to the standard logging location. so: logs stay in the log place, stderr stays clean ✨
  • --nocolor — do not use ANSI colors. the environment variable NO_COLOR can be used as an alternative to --nocolor. some people fear the rainbow 🌈 (not me tho).
  • -V, --version — prints mu version and copyright information. the receipts 👑
  • -h, --help — lists the various command line options. very meta of her, we love a self-aware icon.

💀 EXIT CODE 💀

this command returns 0 upon successful completion, or a non-zero exit code otherwise. here's the whole roster:

  1. 0. success 🎉
  2. 2. no matches found. try a different query 🔍
  3. 11. database schema mismatch. you need to re-initialize mu, see mu-init(1) 🚨
  4. 19. failed to acquire lock. some other program has exclusive access to the mu database 😤 main character energy but make it possessive
  5. 99. caught an exception 💀
not all of these are about mu help specifically, but they're the exit codes of the family, so now you know them by heart. no cap.
