💖 SYSTUNEDUMP 💖

okay so bestie, this is systunedump from section 8 of the manual (that's the sysadmin girlies section, iykyk). she lives in Debian GNU/Linux and she has ONE job: dumping /proc files for kernel tuning. that's it. that's the whole personality. and she ate. 💅

✨ NAME ✨

systunedump — dumps /proc files for kernel tuning. literally what it says on the tin, no cap. 🫶

🌸 SYNOPSIS 🌸

systunedump [ -c,--config configfile ] [ -h, --help ] [ -p, --path
dumppath ] [ -v, --verbose ]

🦋 DESCRIPTION 🦋

so this program dumps elements of the /proc filesystem to standard output, in a format that — if you redirect it into a file — can be used by the systune(8) utility. it's giving "handing off the vibe to the next girl". ✨

common usage, aka the three moods:

systunedump > /etc/systune.conf
systunedump --config /etc/systune.kernel20.dump >
/etc/systune.kernel20.conf
systunedump --config /dev/null --path /proc/sys/vm > /etc/systune.conf

💅 OPTIONS 💅

  • -c, --config configfile — specify an alternative configuration file. the default is /etc/systune.dump. (yes she has a default, she's prepared. main character energy. 👑)
  • -h, --help — print a short explanation of the command syntax. your girl is helpful like that. 🎀
  • -p, --path dumppath — add the specified path to any items already listed in the configuration file. items in the path must be separated by whitespace. and every single item in the path must begin /proc/sys/. no exceptions bestie, that's the rule. ⭐
  • -v, --verbose — verbose mode: allow non-existent items in the path and configuration file to produce errors to standard error. without this option, erroneous paths are discarded silently. like, ghosted. 💀 so if you're confused why something vanished, that's why — turn on -v and she'll actually tell you what's wrong. 🫶

🌈 FILES 🌈

  • /etc/systune.dump — a file containing a list of paths to dump. each pathname must begin with /proc/sys/. comments are a thing here! introduce them with #, and the whole line from the comment character onwards gets discarded, together with any whitespace immediately preceding it. (so you can be as chatty in the comments as you want, it's giving journaling. 📓✨)

the configuration file can also be a file — like /etc/systune.conf — that contains previously dumped data. in that case, the definition part of each line, after and including the colon, is discarded. so like, the data part gets tossed, no hard feelings. 🙈
