Linux 2.6 - man page for findmnt (linux section 8)

FINDMNT(8)									       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 out-
	      put 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 speci-
	      fied 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 format-
	      ting 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.
