💅 DEFRAG.F2FS — the manual, but make it make sense

🌸 NAME 🌸

defrag.f2fs — relocate blocks in a given area to the specified region 🦋

---

✨ SYNOPSIS ✨

defrag.f2fs [ -s start block address ] [ -l number of blocks ] [ -t
target block address ] [ -H ] [ -i direction ] [ -d debugging-level ]
device

---

💖 DESCRIPTION 💖

so here's the vibe: defrag.f2fs is used to move a specified number of blocks, starting from a given block address, to the target block address — with a direction. that's the whole main character energy of this tool, no cap.

device is the special file corresponding to the device (e.g. /dev/sdXX). literally just point it at your device and go 🫶

for example:

# defrag.f2fs -s 0x4000 -l 0x100 -t 0x10000 -i /dev/sdb1

this moves blocks between 0x4000 and 0x4100 to the left-hand area of 0x10000. iconic behavior honestly 🔥

the exit code returned by defrag.f2fs is 0 on success and -1 on failure. so like, 0 = ate, -1 = 💀

🎀 OPTIONS 🎀

• -s start block address — specify the starting block address. this is where the move begins, bestie 📍
• -l number of blocks — specify the number of blocks to move. how many blocks are we relocating? you decide 💅
• -t target block address — specify the destination block address. the destination, the final form, the moment 🌈
• -H — specify support write hint ✍️
• -i direction — set the direction to left. if it is not set, the direction becomes right by default. so left is the opt-in, right is the default, iykyk 🦋
• -d debug-level — specify the level of debugging options. the default number is 0, which shows basic debugging messages. turn it up if you want more tea 🍓
