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
Filtering
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/'
Display options
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
Color-coding & Thresholds
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"
Bonus
If you prefer your output as JSON:
duf --json
