.PP
  $ duf /home /some/file
.PP
.PP
If you want to list everything (including pseudo, duplicate, inaccessible file systems):
.PP
.PP
  $ duf --all

You can show and hide specific tables:
.PP
.PP
  $ duf --only local,network,fuse,special,loops,binds
.PP
  $ duf --hide local,network,fuse,special,loops,binds
.PP
.PP
You can also show and hide specific filesystems:
.PP
.PP
  $ duf --only-fs tmpfs,vfat
.PP
  $ duf --hide-fs tmpfs,vfat
.PP
.PP
\&.\&.\&.or specific mount points:
.PP
.PP
  $ duf --only-mp /,/home,/dev
.PP
  $ duf --hide-mp /,/home,/dev
.PP
.PP
Wildcards inside quotes work:
.PP
.PP
  $ duf --only-mp '/sys/*,/dev/*'
.PP
.PP
Sort the output:
.PP
.PP
  $ duf --sort size
.PP
.PP
Valid keys are: mountpoint, size, used, avail, usage, inodes, inodes_used, inodes_avail, inodes_usage, type, filesystem\&.

Show or hide specific columns:
.PP
.PP
  $ duf --output mountpoint,size,usage
.PP
