✨ NAME ✨

resizepart — tell the kernel about the new size of a partition

like. that's it. that's the whole job. no cap. 🎀

---

🌸 SYNOPSIS 🌸

resizepart device partition length

three lil arguments, one big vibe. let's get into it 🦋

---

💅 DESCRIPTION 💅

So. resizepart tells the Linux kernel about the new size of the specified partition. That's the whole assignment. periodt. 💖

And the way it does it?? It's just a simple wrapper around the "resize partition" ioctl. That's it. No drama, no extra steps, no weird side quests. lowkey iconic. ✨

🚨 but listen — this command doesn't manipulate partitions on a block device. Read that again. It does NOT touch the actual partition table situation on your disk. It's just the messenger telling the kernel "hey bestie, new size, ok bye". Do not come for it expecting it to edit your partitions. It won't. 🙈

🎀 PARAMETERS 🎀

• device — the disk device. yes, THE disk. the whole thing. 👑
• partition — the partition number. just the number, babe, not the whole path. 🔢
• length — the new length of the partition, measured in 512-byte sectors. remember: sectors, not bytes, not megabytes. 512-byte sectors. iykyk. 📏
• -h, --help — display help text and exit. your lil "wait what does this do again" safety net 🫶
• -V, --version — display version and exit. for when you gotta know exactly which build you're working with 💅
