FINDMNT(8)

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