The optional argument when can be set to "auto", "never", or "always". If the when argument is omitted, it will default to "auto". The "auto" setting means that hyperlinks will only be used if the output is on a terminal. -F, --tab-file . --fstab, --mtab --kernel, . , (. --list). -f, --first-only . -H, --list-columns List the available columns, use with --json or --raw to get output in machine-readable format. -I, --dfi df(1) -i. -o SOURCE,FSTYPE,INO.TOTAL,INO.USED,INO.AVAIL,INO.USE%,TARGET, . --all . -i, --invert . --id . --uniq-id Select a filesystem using the mount node 64-bit ID, use with --kernel=listmount option. -J, --json B JSON. -k, --kernel[=] Reads information about filesystems from the kernel. This is the default output. The format is tree-like and only includes mount options managed by the kernel (see also --mtab). ' : o mountinfo - this is the default method and it reads data from the /proc/self/mountinfo file. o listmount - This is an EXPERIMENTAL method that uses the listmount() and statmount() syscalls to generate the mount table.
