✨ PRELOAD ✨ (that's the preload(8) girlies — system administration utilities energy 💅)

okay so bestie, sit DOWN, because this little daemon is about to make your app startup times absolutely slay 🦋

🌸 NAME 🌸

preload — the adaptive readahead daemon, aka your apps' personal hype squad 🎀

⭐ SYNOPSIS ⭐

preload [OPTION]...

that's it. that's the whole vibe. options only, no positional drama 🙈

💖 DESCRIPTION 💖

okay so preload is an adaptive readahead daemon — which is a fancy way of saying it prefetches the files your applications map from the disk, so that when you actually go to open them, everything is already warm and cozy and your startup time goes 📉 down. it's literally doing the homework before the teacher assigns it. main character energy fr fr 👑

and here are all the flags, no cap, every single one:

  • -h, --help — shows you the command line parameters AND their default values, then dips. cute, informative, no notes ✨
  • -v, --version — prints the version info and exits. the "who am i" moment 🪞
  • -c, --conffile — set the configuration file. an empty string means no conf file at all, bestie. (default is /etc/preload.conf) 🗂️
  • -s, --statefile — set the state file to load/save. empty string means no state, like, at all. (default is /var/lib/preload/preload.state) 💾
  • -l, --logfile — set the log file. empty string means log to stderr instead. (default is /var/log/preload.log) 📝
  • -f, --foreground — run in the foreground, do NOT daemonize. she stays right there with you, holding your hand 🫶
  • -n, --nice — the nice level. (default is 15) 😇
  • -V, --verbose — set the verbosity level. levels 0 to 10 are recognized, so pick your yapping intensity. (default is 4) 🗣️
  • -d, --debug — debug mode, which is literally just --logfile '' --foreground --verbose 9 all bundled up. maximum chaos, maximum output 💀

🔔 SIGNALS 🔔

she listens, okay? she's a good listener. here's what makes her do stuff:

  • on receipt of a SIGHUP, the daemon will close and reopen its log file, AND reread the configuration file. glow-up + re-education moment 🌈
  • on receipt of a SIGUSR1, the daemon dumps the currently loaded configuration into the log file. like a diary entry but for settings 📓
  • on receipt of a SIGUSR2, the daemon saves its state into the state file. she's preserving herself for the future, iconic behavior 👑
