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,
−−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
wordThe 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
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:
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
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,
−−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
.
−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.
