💖 RMCP 💖

okay bestie, so rmcp is the little unix homie that lives in your System Manager's Manual (section 8, so you know it's admin-coded 💅), and its whole job? removing NILFS2 checkpoints. that's it. that's the gig. she's a deleter, not a collector. 🎀

✨ NAME ✨

rmcp — remove NILFS2 checkpoints. no cap, that's literally the entire name section. short, sweet, iconic. 👑

🌸 SYNOPSIS 🌸

rmcp [options] [device|node] checkpoint-range ...

so it's rmcp, then some options if you feel like it, then optionally a device or a node, then one or more checkpoint-ranges. and yes the ... is doing heavy lifting there — you can hand her a whole lil list of ranges and she'll go through them. 💖

🦋 DESCRIPTION 🦋

so rmcp is a utility for removing checkpoints from the NILFS2 file system found in device. the checkpoints you wanna yeet get specified with one or more checkpoint-ranges. periodt. 🫶

and listen — device is flexible like that: it can be a block device, or it can be a filesystem node (like, a file or a directory) that lives on the filesystem. super chill, either one works. 🧚

but what if I don't give her a device at all?? okay so if you omit device, rmcp goes looking for a NILFS2 file system by checking /proc/mounts. she's resourceful. she'll find it herself. ✨

now, the checkpoint-range — this is the part where you gotta be precise, bestie. it must be given with one or two integers, in exactly one of these flavors:

  • cno — a single checkpoint number. just one. one (1) checkpoint. simple as that. 💅
  • start..end — every checkpoint number between start and end. the whole range, babe. 🌈
  • ..end — every checkpoint number equal or younger than end. so everything up to and including end. 🌸
  • start.. — every checkpoint number equal or greater than start. so everything from start onwards, no upper limit. 🦋
⚠️ big important warning energy: this command is valid only for mounted NILFS2 file systems. if the device has no active mounts, she's gonna fail. not "try harder", not "figure it out" — fail. so mount that thing first, okay? 😭

💅 OPTIONS 💅

  • -f, --force — ignore snapshots or nonexistent checkpoints. basically "idc if it's a snapshot, idc if it doesn't exist, we're doing this anyway." 💀
  • -i, --interactive — prompt before any removal. she'll ask you first, like a polite queen. one checkpoint at a time, consent is key. 🎀
  • -h, --help — display help message and exit. the "wait what do I do" button. 🫶
  • -V, --version — display version and exit. for when you just gotta know what build you're running. ⭐
