UML_MOO(1)

💖 UML_MOO(1) — the merge-y bestie 💖

okay so this is a page from the General Commands Manual, and it's all about a lil program called uml_moo. buckle up 🎀

✨ NAME ✨

uml_moo — merge a COW file with its backing file 🐄💫

🌸 SYNOPSIS 🌸

uml_moo [COW file]  [new_backing_file]

🦋 DESCRIPTION 🦋

so this manual page is gonna give you the brief rundown on the uml_moo command, bestie. no gatekeeping here 💅

this manual page was written for the Debian GNU/Linux distribution because the original program straight up does not have a manual page 😭. instead, it has documentation in HTML format — peep the SEE ALSO section below for the deets.

uml_moo is a program that merges a COW (copy-on-write) file with its backing file, and then writes the result to a new backing file ✨. you can run this periodically to update the backing file with all the changes that got made in the COW file. it's giving housekeeping, it's giving spring cleaning 🧹

NOTE: you can save a lot of disk space using COW files 🫶. but when you're checking the size of the COW file to admire all the gobs of space you're saving, make sure you use ls -ls to see the actual disk consumption, not the length of the file. the COW file is sparse, so the length will be very different from the disk usage. don't get played by a number that's lying to you 😭 no cap.
