FSCK.CRAMFS(8)

💅 FSCK.CRAMFS 💅

okay bestie, so fsck.cramfs is the little icon from the util-linux family — it's a manual page from section 8 (that's the System Administration girlies), and she's here to check your cramfs file system. that's the whole job. no cap.

---

✨ NAME ✨

fsck.cramfs — fsck compressed ROM file system 🦋

---

✨ SYNOPSIS ✨

fsck.cramfs [options] file

---

✨ DESCRIPTION ✨

so basically fsck.cramfs is used to check the cramfs file system. that's it, that's the vibe. she checks. she does not fix. we love a focused queen 💅

---

✨ OPTIONS ✨

• -v, --verbose — turn on verbose messaging. she will yap and honestly? let her.
• -b, --blocksize blocksize — use this blocksize instead of the default, which is the page size. ⚠️ it must be equal to whatever was set at creation time, no negotiating. also, heads up: this one is only used for --extract.
• --extract[=directory] — test by uncompressing the whole file system. and if you feel like it, you can optionally extract the contents of the file into directory. so it's giving "verify, but also gimme the goods" 💖
• -a — this option is silently ignored. she does not see it. she does not acknowledge it. it's not on her calendar. 🫥
• -y — this option is silently ignored too. same energy. same silence. 🙈
• -h, --help — display help text and exit. classic.
• -V, --version — display version and exit. also classic.

---

✨ EXIT STATUS ✨

she speaks through numbers, bestie, here's the decoder ring:

• 0 — success ✨ everything's slay.
• 4 — file system was left uncorrected. not the outcome we wanted ngl 😭
• 8 — operation error, like for real real errors — e.g. unable to allocate memory 💀
• 16 — usage information was printed.

---

✨ SEE ALSO ✨

mount(8), mkfs.cramfs(8) — the rest of the friend group 🫶

---

✨ REPORTING BUGS ✨

found a bug? don't @ her in the group chat, take it to the issue tracker instead:

<https://github.com/util-linux/util-linux/issues>

(technically it's the util-linux issue tracker, but that link is the whole thing, copy it exactly 💖)

---

✨ AVAILABILITY ✨

the fsck.cramfs command is part of the util-linux package, which you can download from the Linux Kernel Archive:

<https://www.kernel.org/pub/linux/utils/util-linux/>

---

lowkey important reminder: -a and -y are silently ignored, and -b only matters when you're using --extract. don't come for me, that's just what the page says 💅

---

and that's the whole page, bestie — brought to you by util-linux 2.42.4, dated 2026-09-21, same as FSCK.CRAMFS(8) in the manual. go check that file system, you got this 👑🎀🌸
