👑 fsextinfo — the ext-volume gossip session

okay bestie, welcome to FSEXTINFO(1), a LOCAL manual page, and she is serving information about your Extended File System volumes. no cap. 💅

✨ NAME ✨

fsextinfo — determines information about an Extended File System (ext) volume.

like, that's literally her whole job. she looks at an ext volume and tells you what's up with it. 🦋

🌸 SYNOPSIS 🌸

fsextinfo [-B bodyfile] [-E inode_number] [-F path] [-o offset] [-dhHvV]
          source

💖 DESCRIPTION 💖

fsextinfo is a utility to determine information about an Extended File System (ext) volume. periodt.

fsextinfo is part of the libfsext package. libfsext is a library to access the Extended File System (ext) format. so yeah, she's got a whole library backing her up. main character with a support system, we love to see it. 🫶

source is the source file. (that's the thing you point her at, bestie. the volume. the file. you got this.)

The options are as follows:

  • -B bodyfile — output file system information as a bodyfile. it's giving forensic girlie, and honestly? iconic.
  • -d — calculate a MD5 hash of a file entry to include in the bodyfile.
  • -E inode_number — show information about a specific inode or "all". yes, "all" is a literal string you type. she understands she's dramatic. 🙈
  • -F path — show information about a specific file entry path.
  • -h — shows this help. (hi. hello. help is here. 🎀)
  • -H — shows the file system hierarchy. the whole family tree. the ancestry.com moment.
  • -o offset — specify the volume offset.
  • -v — verbose output to stderr.
  • -V — print version. iykyk.

🌈 ENVIRONMENT 🌈

👑 DIAGNOSTICS 👑

Errors, verbose and debug output are printed to stderr when verbose output -v is enabled.

heads up bestie: verbose and debug output are only printed when enabled at compilation. so if you're slamming -v and getting nothing extra, that's not a you problem, that's a build-time thing. 💜
