OOMCTL(1)

💅 OOMCTL(1) — the oomctl era

ok so bestie, welcome to oomctl, a page from manual section 1 (that's the "commands you just type" section, iykyk). Buckle up, this one's short and honestly kind of a vibe.

---

✨ NAME ✨

oomctl — analyze the state stored in systemd-oomd. that's it. that's the whole job. she's a state-inspector and she's slaying at it 💅

---

🦋 SYNOPSIS 🦋

oomctl [OPTIONS...] {COMMAND}

options first, then a command — like outfit first, then the fit check. simple.

---

🌸 DESCRIPTION 🌸

so oomctl is your little window into the various contexts that get read in by the systemd(1) userspace out-of-memory (OOM) killer, aka systemd-oomd(8). (yes, the thing that unalives your memory-hungry processes before your whole session goes down. dramatic, but necessary 🫶)

think of it as the group chat where oomd spills everything she's currently holding onto. you're just here to read the messages, lowkey.

---

👑 COMMANDS 👑

these are the commands she understands, fr fr:

• dump — show the current state of the cgroups and system contexts stored by systemd-oomd. that's the whole tea ☕ the cgroup contexts, the system contexts, all of it, dumped out for your reading pleasure ✨

Added in version 247. (so if you're on something older, she simply wasn't born yet 😭)

---

💖 OPTIONS 💖

these are the options she gets. all three of them. she's not complicated and that's iconic:

• -h, --help — print a short help text and exit. the "who are you and what do you do" option 🎀
• --version — print a short version string and exit. the "how old are you" option 💀
• --no-pager — do not pipe output into a pager. for when you simply cannot with the scrolling situation and want everything dumped straight to your terminal, no less moment, no waiting 🙈

---

⭐ EXIT STATUS ⭐

• on success, 0 is returned. slay. 🎉
• otherwise you get a non-zero failure code. not slay. something went sideways and she's telling you about it 😭

---

🌈 SEE ALSO 🌈

go read these too, bestie, they're all in the family:

• systemd(1)
• systemd-oomd.service(8)
• oomd.conf(5)

---

ok that's the whole page, no cap. she's small, she's focused, she does one thing and she does it well 🧚‍♀️

this has been oomctl, brought to you by systemd 261.3 — now go dump some contexts and have the day you deserve 💜🌸✨
