Findmnt kasutamine

findmnt will list all mounted filesystems or search for a filesystem. The findmnt command is able to search in /etc/fstab, /etc/mtab or /proc/self/mountinfo. If device or mountpoint is not given, all filesystems are shown.

The device may be specified by device name, major:minor numbers, filesystem label or UUID, or partition label or UUID. Note that findmnt follows mount(8) behavior where a device name may be interpreted as a mountpoint (and vice versa) if the --target, --mountpoint or --source options are not specified.

The command prints all mounted filesystems in the tree-like format by default.

Võtmed

-A, --all Disable all built-in filters and print all filesystems.

-a, --ascii Use ascii characters for tree formatting.

-b, --bytes Print the SIZE, USED and AVAIL columns in bytes rather than in a human-readable format.

-C, --nocanonicalize Do not canonicalize paths at all. This option affects the comparing of paths and the evaluation of tags (LABEL, UUID, etc.).

-c, --canonicalize Canonicalize all printed paths.

-D, --df Imitate the output of df(1). This option is equivalent to -o SOURCE,FSTYPE,SIZE,USED,AVAIL,USE%,TARGET but excludes all pseudo filesystems. Use --all to print all filesystems.

-d, --direction word The search direction, either forward or backward.

-e, --evaluate Convert all tags (LABEL, UUID, PARTUUID or PARTLABEL) to the corresponding device names.

-F, --tab-file path Search in an alternative file. If used with --fstab, --mtab or --kernel, then it overrides the default paths. If specified more than once, then tree-like output is disabled (see the --list option).

-f, --first-only Print the first matching filesystem only.

-h, --help Display help text and exit.

-i, --invert Invert the sense of matching.

-J, --json Use JSON output format.

-k, --kernel Search in /proc/self/mountinfo. The output is in the tree- like format. This is the default. The output contains only mount options maintained by kernel (see also --mtab).

-l, --list

             Use the list output format.  This output format is
             automatically enabled if the output is restricted by the -t,
             -O, -S or -T option and the option --submounts is not used or
             if more that one source file (the option -F) is specified.

-M, --mountpoint path

             Explicitly define the mountpoint file or directory.  See also
             --target.

-m, --mtab

             Search in /etc/mtab.  The output is in the list format by
             default (see --tree).  The output may include user space mount
             options.

-p, --poll[=list]

             Monitor changes in the /proc/self/mountinfo file.  Supported
             actions are: mount, umount, remount and move.  More than one
             action may be specified in a comma-separated list.  All
             actions are monitored by default.

             The time for which --poll will block can be restricted with
             the --timeout or --first-only options.

             The standard columns always use the new version of the
             information from the mountinfo file, except the umount action
             which is based on the original information cached by
             findmnt(8).  The poll mode allows to use extra columns:

             ACTION mount, umount, move or remount action name; this column
                    is enabled by default

             OLD-TARGET
                    available for umount and move actions

             OLD-OPTIONS
                    available for umount and remount actions

      -R, --submounts
             Print recursively all submounts for the selected filesystems.
             The restrictions defined by options -t, -O, -S, -T and
             --direction are not applied to submounts.  All submounts are
             always printed in tree-like order.  The option enables the
             tree-like output format by default.  This option has no effect
             for --mtab or --fstab.

      -r, --raw
             Use raw output format.  All potentially unsafe characters are
             hex-escaped (\x).

      -S, --source spec
             Explicitly define the mount source.  Supported specifications
             are device, maj:min, LABEL=label, UUID=uuid, PARTLABEL=label
             and PARTUUID=uuid.

      -s, --fstab
             Search in /etc/fstab.  The output is in the list format (see
             --list).

-x, --verify Check mount table content.

--verbose Force findmnt to print more information
