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
              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  ACTION,  SOURCE,  TARGET,  OLD-TARGET,  FSTYPE,
              OPTIONS,  OLD-OPTIONS,  VFS-OPTIONS,  FS-OPTIONS, LABEL and UUID.  The TARGET column contains tree
              formatting if the --list or --raw options are not specified.

       -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, --raw
              Use raw output format.

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

       -t, --types list
              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= and UUID=.

       -T, --target dir
              Explicitly define the mount target (mountpoint directory).

       -w, --timeout milliseconds
              Specify an upper limit on the time for which --poll will block, in milliseconds.

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.

       findmnt --poll --target /mnt/foo
              Monitors mount, umount, remount and move on /mnt/foo.

       findmnt --poll=umount --first-only --target /mnt/foo
              Waits for /mnt/foo umount.

       findmnt --poll=remount -t ext3 -O ro
              Monitors remounts to read-only mode on all ext3 filesystems.
