💖 FINDFS(8) — findfs 💖

system administration era ✨ like, the manual page for findfs, bestie 🎀

---

🌸 NAME 🌸

findfs — find a filesystem by label or UUID 🦋

---

✨ SYNOPSIS ✨

findfs TAGNAME=value

---

💅 DESCRIPTION 💅

okay so listen. findfs goes snooping through all the block devices on your system looking for a filesystem or a partition that matches the tag you handed it. it's giving detective energy 🔍✨

the tags it supports rn are:

• LABEL=label — specifies a filesystem label 💖
• UUID=uuid — specifies a filesystem UUID 🌈
• PARTUUID=uuid — specifies a partition UUID. partition identifiers are supported for example for GUID Partition Table (GPT) partition tables 👑
• PARTLABEL=label — specifies a partition label (name). partition labels are supported for example for GPT and MAC partition tables 🎀

so if the filesystem or partition actually gets found?? the device name gets printed on stdout, periodt ✨ and if your input is not in the TAGNAME=value format, then the input gets copied straight to the output with zero modification. no notes. 💅

and if you wanna get a complete overview of the filesystems and partitions chilling in your system, run one of these bestie:

lsblk --fs

partx --show disk

blkid
