6 findmnt - find a filesystem
7
9 findmnt [options]
10 findmnt [options] device|mountpoint
12 findmnt [options] [--source] device [--target] mountpoint
14
16 findmnt will list all mounted filesytems or search for a filesystem.
17 The findmnt command is able to search in /etc/fstab, /etc/mtab or
18 /proc/self/mountinfo. If device or mountpoint is not given, all
19 filesystems are shown.
20 The command prints all mounted filesystems in the tree-like format by
22 default.
23
25 -h, --help
26 Print help and exit.
27 -s, --fstab
29 Search in /etc/fstab. The output is in the list format (see
30 --list).
31 -m, --mtab
33 Search in /etc/mtab. The output is in the list format (see
34 --list).
35 -k, --kernel
37 Search in /proc/self/mountinfo. The output is in the tree-like
38 format. This is the default.
39 -c, --canonicalize
41 Canonicalize all printed paths.
42 -d, --direction word
44 The search direction - forward or backward.
45 -e, --evaluate
47 Convert all tags (LABEL or UUID) to the device names.
48 -f, --first-only
50 Print the first matching filesystem only.
51 -i, --invert
53 Invert the sense of matching.
54 -l, --list
56 Use the list output format.
57 -n, --noheadings
59 Do not print a header line.
60 -u, --notruncate
62 Do not truncate text in columns. The default is to not truncate
63 the TARGET, SOURCE, UUID and LABEL columns. This option dis‐
64 ables text truncation also in all other columns.
65 -O, --options list
67 Used to limit the set of printed filesystems. More than one
68 option may be specified in a comma-separated list. The -t and
69 -O options are cumulative in effect. It is different from -t in
70 that each option is matched exactly; a leading no at the begin‐
71 ning of one option does not negate the rest. For more details
72 see mount(8).
73 -o, --output list
75 Define output columns. Currently supported are SOURCE, TARGET,
76 FSTYPE, OPTIONS, VFS-OPTIONS, FS-OPTIONS, LABEL and UUID. The
77 TARGET column contains tree formatting if the --list or --raw
78 options are not specified.
79 -r, --raw
81 Use raw output format.
82 -a, --ascii
84 Use ascii characters for tree formatting.
85 -t, --types list
87 Used to limit the set of printed filesystems. More than one
88 type may be specified in a comma-separated list. The list of
89 filesystem types can be prefixed with no to specify the filesys‐
90 tem types on which no action should be taken. For more details
91 see mount(8).
92 -S, --source spec
94 Explicitly define the mount source. Supported are device,
95 LABEL= or UUID=.
96 -T, --target dir
98 Explicitly define the mount target (mountpoint directory).
99
101 findmnt --fstab -t nfs
102 Prints all nfs filesystems defined in /etc/fstab.
103 findmnt --fstab /mnt/foo
105 Prints all /etc/fstab filesystems where the mountpoint directory
106 is /mnt/foo. It also prints bind mounts where /mnt/foo is a
107 source.
108 findmnt --fstab --target /mnt/foo
110 Prints all /etc/fstab filesystems where the mountpoint directory
111 is /mnt/foo.
112 findmnt --fstab --evaluate
114 Prints all /etc/fstab filesystems and converts LABEL= and UUID=
115 tags to the real device names.
116 findmnt -n --raw --evaluate --output=target LABEL=/boot
118 Prints only the mountpoint where the filesystem with label
119 "/boot" is mounted.
