GIT-MAILSPLIT(1)

💌 GIT-MAILSPLIT(1) 💌

okay bestie, welcome to git-mailsplit — the simple UNIX mbox splitter program, and when I say simple I mean it does one thing and it slays at it ✨

---

🌸 SYNOPSIS 🌸

git mailsplit [-b] [-f<nn>] [-d<prec>] [--keep-cr] [--mboxrd]
                -o<directory> [--] [(<mbox>|<Maildir>)...]

---

🎀 DESCRIPTION 🎀

So here's the vibe: this little icon takes a mbox file or a Maildir and splits it into a whole list of files — "0001", "0002", and so on — all dropped into the directory you specify. Then you can go process them from there whenever you're ready. Literally the ultimate glow-up for a giant blob of mail 💅

⚠️ Important, fr fr: Maildir splitting relies upon filenames being sorted to output patches in the correct order. No cap — if the sorting's off, the order's off. 🫶

✨ OPTIONS ✨

• <mbox> — the mbox file you wanna split. If you don't hand one over, it just reads the mbox from standard input. lowkey chill of it.
• <Maildir> — the root of the Maildir you're splitting. Heads up: this directory should contain the cur, tmp and new subdirectories. 🗂️
• -o<directory> — the directory where all the individual messages get placed. yes you need this, it's not optional bestie.
• -b — if any file doesn't start with a From line, just assume it's a single mail message instead of throwing an error. forgiving queen behavior 👑
• -d<prec> — the default is 4 digits with leading zeros, but you can specify a different precision for the generated filenames if 4 isn't your moment.
• -f<nn> — skip the first <nn> numbers. so like, if you pass -f3, the numbering starts at 0004. math! 🔥
• --keep-cr — do not remove \r from lines ending with \r\n. keep that carriage return, let it live its life 💀
• --mboxrd — tells it the input is in "mboxrd" format, and that "^>+From " line escaping is reversed. iykyk 🦋
