⊕ Usage

df [ options ] [ files-or-directories ]

⊕ Purpose

 

Show the inode or space usage in one or more filesystems.

⊕ Major options

 

-i

 

Show inode counts rather than space.

 

Show space in kilobytes rather than blocks.

 

Lowercase L. Show only local filesystems.

⊕ Behavior

 

For each file or directory argument, or for all filesystems if there are no such arguments, df produces a one-line header that identifies the output columns, followed by a usage report for the filesystem containing that file or directory.

⊕ Caveats

 

The output of df varies considerably between systems, making it hard to use reliably in portable shell scripts.

 

df's output is not sorted.
