NAME

findmnt - find a filesystem

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/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. 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.
-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).
-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 -n --raw --evaluate --output=target LABEL=/boot: Prints only the mountpoint where the filesystem with label "/boot" is mounted.
