24.4.3. Using the findmnt Command
The
findmnt command allows you to display a list of currently mounted file systems. To do so, type the following at a shell prompt:
findmnt
For each listed file system, the
findmnt command displays the target mount point (TARGET), source device (SOURCE), file system type (FSTYPE), and relevant mount options (OPTIONS). For example:
~]$ findmnt
TARGET SOURCE FSTYPE OPTIONS
/ /dev/mapper/vg_kvm-lv_root ext4 rw,relatime,sec
|-/proc /proc proc rw,relatime
| |-/proc/bus/usb /proc/bus/usb usbfs rw,relatime
| `-/proc/sys/fs/binfmt_misc binfmt_m rw,relatime
|-/sys /sys sysfs rw,relatime,sec
|-/selinux selinuxf rw,relatime
|-/dev udev devtmpfs rw,relatime,sec
| `-/dev udev devtmpfs rw,relatime,sec
| |-/dev/pts devpts devpts rw,relatime,sec
| `-/dev/shm tmpfs tmpfs rw,relatime,sec
|-/boot /dev/vda1 ext4 rw,relatime,sec
|-/var/lib/nfs/rpc_pipefs sunrpc rpc_pipe rw,relatime
|-/misc /etc/auto.misc autofs rw,relatime,fd=
`-/net -hosts autofs rw,relatime,fd=

By default,
findmnt lists file systems in a tree-like format. To display the information as an ordinary list, add the -l command-line option:
findmnt-l
For instance:
~]$ findmnt -l
TARGET SOURCE FSTYPE OPTIONS
/proc /proc proc rw,relatime
/sys /sys sysfs rw,relatime,seclabe
/dev udev devtmpfs rw,relatime,seclabe
/dev/pts devpts devpts rw,relatime,seclabe
/dev/shm tmpfs tmpfs rw,relatime,seclabe
/ /dev/mapper/vg_kvm-lv_root ext4 rw,relatime,seclabe
/selinux selinuxf rw,relatime
/dev udev devtmpfs rw,relatime,seclabe
/proc/bus/usb /proc/bus/usb usbfs rw,relatime
/boot /dev/vda1 ext4 rw,relatime,seclabe
/proc/sys/fs/binfmt_misc binfmt_m rw,relatime
/var/lib/nfs/rpc_pipefs sunrpc rpc_pipe rw,relatime
/misc /etc/auto.misc autofs rw,relatime,fd=7,pg
/net -hosts autofs rw,relatime,fd=13,p

You can also choose to list only file systems of a particular type. To do so, add the
-t command-line option followed by a file system type:
findmnt-ttype
For example, to list all
ext4 file systems, type:
~]$ findmnt -t ext4
TARGET SOURCE FSTYPE OPTIONS
/ /dev/mapper/vg_kvm-lv_root ext4 rw,relatime,seclabel,barrier=1,data=ord
/boot /dev/vda1 ext4 rw,relatime,seclabel,barrier=1,data=ord
For a complete list of available command-line options, see the findmnt(8) manual page.
