SYNOPSIS

findmnt [options]

findmnt [options] device|mountpoint

findmnt [options] [--source] device [--target] mountpoint

DESCRIPTION

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

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

OPTIONS

-h, --help Print help and exit.
-s, --fstab Search in /etc/fstab and /etc/fstab.d. The output is in the list format (see --list).
-m, --mtab Search in /etc/mtab. The output is in the list format (see --list).
-k, --kernel Search in /proc/self/mountinfo. The output is in the tree-like format. This is the default.
-c, --canonicalize Canonicalize all printed paths.
-d, --direction word The search direction - forward or backward.
-e, --evaluate Convert all tags (LABEL or UUID) to the device names.
-f, --first-only Print the first matching filesystem only.
-i, --invert Invert the sense of matching.
-l, --list Use the list output format. This output format is automatically enabled if the output is restricted by -t, -O, -S or -T option and the option --submounts is not used.
-v, --nofsroot Do not print a [/dir] in the SOURCE column for bind-mounts or btrfs subvolumes.
-n, --noheadings Do not print a header line.
-u, --notruncate Do not truncate text in columns. The default is to not truncate the TARGET, SOURCE, UUID and LABEL columns. This option disables text truncation also in all other columns.
-O, --options list Used to limit the set of printed filesystems. More than one option may be specified in a comma-separated list. The -t and -O options are cumulative in effect. It is different from -t in that each option is matched exactly; a leading no at the beginning of one option does not negate the rest. For more details see mount(8).
-o, --output list Define output columns. Currently supported are SOURCE, TARGET, FSTYPE, OPTIONS, VFS-OPTIONS, FS-OPTIONS, LABEL and UUID. The TARGET column contains tree formatting if the --list or --raw options are not specified.
-r, --raw Use raw output format.
-a, --ascii Use ascii characters for tree formatting.
-t, --types list Used to limit the set of printed filesystems. More than one type may be specified in a comma-separated list. The list of filesystem types can be prefixed with no to specify the filesystem types on which no action should be taken. For more details see mount(8).
-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.
-S, --source spec Explicitly define the mount source. Supported are device, LABEL= or UUID=.
-T, --target dir Explicitly define the mount target (mountpoint directory).

EXAMPLES

findmnt --fstab -t nfs Prints all nfs filesystems defined in /etc/fstab.
findmnt --fstab /mnt/foo Prints all /etc/fstab filesystems where the mountpoint directory is /mnt/foo. It also prints bind mounts where /mnt/foo is a source.
findmnt --fstab --target /mnt/foo Prints all /etc/fstab filesystems where the mountpoint directory is /mnt/foo.
findmnt --fstab --evaluate Prints all /etc/fstab filesystems and converts LABEL= and UUID= tags to the real device names.
findmnt Prints only the mountpoint where the filesystem with label "/boot" is mounted.
