mountpoint
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.
−h,
−−helpPrint help and exit.
−s,
−−fstabSearch in /etc/fstab
and /etc/fstab.d. The
output is in the list format (see --list).
−m,
−−mtabSearch in /etc/mtab.
The output is in the list format (see --list).
−k,
−−kernelSearch in /proc/self/mountinfo. The output is
in the tree-like format. This is the default.
−c,
−−canonicalizeCanonicalize all printed paths.
−d,
−−direction wordThe search direction - forward or backward.
−e,
−−evaluateConvert all tags (LABEL or UUID) to the device names.
−f,
−−first−onlyPrint the first matching filesystem only.
−i,
−−invertInvert the sense of matching.
−l,
−−listUse 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,
−−nofsrootDo not print a [/dir] in the SOURCE column for bind-mounts or btrfs subvolumes.
−n,
−−noheadingsDo not print a header line.
−u,
−−notruncateDo 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 listLimit 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 listDefine 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:
ACTIONmount, 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,
−−rawUse raw output format.
−a,
−−asciiUse ascii characters for tree formatting.
−t,
−−types listLimit 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,
−−submountsPrint 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.
−T,
−−target dirExplicitly define the mount source. Supported are
device,
LABEL= and
UUID=.
−T,
−−target dirExplicitly define the mount target (mountpoint directory).
−w,
−−timeout millisecondsSpecify an upper limit on the time for which
−−poll will
block, in milliseconds.
Prints all nfs filesystems defined in /etc/fstab.
Prints all /etc/fstab
filesystems where the mountpoint directory is /mnt/foo.
It also prints bind mounts where /mnt/foo is a
source.
Prints all /etc/fstab
filesystems where the mountpoint directory is
/mnt/foo.
Prints all /etc/fstab
filesystems and converts LABEL= and UUID= tags to the
real device names.
Prints only the mountpoint where the filesystem with label "/boot" is mounted.
Monitors mount, umount, remount and move on /mnt/foo.
Waits for /mnt/foo umount.
Monitors remounts to read-only mode on all ext3 filesystems.
