Usage

You can simply start duf without any command-line arguments:

$ duf

If you supply arguments, duf will only list specific devices & mount points:

$ duf /home /some/file

If you want to list everything (including pseudo, duplicate, inaccessible file systems):

$ duf --all

You can show and hide specific tables:

$ duf --only local,network,fuse,special,loops,binds

$ duf --hide local,network,fuse,special,loops,binds

You can also show and hide specific filesystems:

$ duf --only-fs tmpfs,vfat

$ duf --hide-fs tmpfs,vfat

...or specific mount points:

$ duf --only-mp /,/home,/dev

$ duf --hide-mp /,/home,/dev

Wildcards inside quotes work:

$ duf --only-mp '/sys/*,/dev/*'

Sort the output:

$ duf --sort size

Valid keys are: mountpoint, size, used, avail, usage, inodes, inodes_used, inodes_avail, inodes_usage, type, filesystem.

Show or hide specific columns:

$ duf --output mountpoint,size,usage

Valid keys are: mountpoint, size, used, avail, usage, inodes, inodes_used, inodes_avail, inodes_usage, type, filesystem.

List inode information instead of block usage:

$ duf --inodes

If duf doesn't detect your terminal's colors correctly, you can set a theme:

$ duf --theme light

duf highlights the availability & usage columns in red, green, or yellow, depending on how much space is still available. You can set your own thresholds:

$ duf --avail-threshold="10G,1G"

$ duf --usage-threshold="0.5,0.9"

If you prefer your output as JSON:

$ duf --json
