🌸 MU INFO(1) — the general commands manual, section 1, bestie 🌸

okay so real quick before we dive in: this page lives in section 1 of the manual (the general commands manual), and it's all about mu info. yes, that mu. 💖

✨ NAME ✨

mu-info — show information 🙈

📜 SYNOPSIS 📜

mu [COMMON OPTIONS] info [TOPIC]

💅 DESCRIPTION 💅

mu info is the mu command you hit up when you need the tea about all kinds of topics. here's the lineup, no cap:

  • mu: general mu build information. this is the default one, so if you don't say a topic, this is what you get 🫶
  • store: information about the message store ✨
  • fields: a table with all the query fields and flags 📋
  • maildirs: list all maildirs under the store's root-maildir 📁
⚠️ heads up bestie: while you're running stuff (think mu4e), some of the store information can be delayed because of database caching. it's not broken, it's just ✨fashionably late✨. 💀

🎀 COMMON OPTIONS 🎀

  • -d, --debug — makes mu generate extra debug information, which is lowkey so useful when you're debugging the program itself. all that debug info goes to the standard logging location — go peek at mu(1) for the deets 🐛
  • -q, --quiet — makes mu stop printing informational messages and progress info to standard output, and sends them to the log file only. error messages still go to standard error though, we're not hiding those 🙅‍♀️. also: mu index is much faster with --quiet, so if you're calling mu from scripts etc., this is the move. periodt. 🔥
  • --log-stderr — causes mu to not output log messages to standard error, in addition to sending them to the standard logging location 🪵
  • --nocolor — do not use ANSI colors 🎨. the environment variable NO_COLOR can be used as an alternative to --nocolor, iykyk
  • -V, --version — prints mu version and copyright information 👑
  • -h, --help — lists the various command line options 🙋‍♀️

💀 EXIT CODE 💀

this command returns 0 when it completes successfully, or a non-zero exit code otherwise. vibe check time:

  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 🔒
  5. 99 — caught an exception 💥
