16.4.4. 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_fedora-lv_root
ext4 rw,relatime,seclabel,data=o
|-/proc proc proc rw,nosuid,nodev,noexec,rela
| `-/proc/sys/fs/binfmt_misc systemd-1 autofs rw,relatime,fd=23,pgrp=1,ti
|-/sys sysfs sysfs rw,nosuid,nodev,noexec,rela
| |-/sys/kernel/security securityfs security rw,nosuid,nodev,noexec,rela
| |-/sys/fs/selinux selinuxfs selinuxf rw,relatime
| |-/sys/fs/cgroup tmpfs tmpfs rw,nosuid,nodev,noexec,secl
| | |-/sys/fs/cgroup/systemd cgroup cgroup rw,nosuid,nodev,noexec,rela
| | |-/sys/fs/cgroup/cpuset cgroup cgroup rw,nosuid,nodev,noexec,rela
| | |-/sys/fs/cgroup/cpu,cpuacct cgroup cgroup rw,nosuid,nodev,noexec,rela
| | |-/sys/fs/cgroup/memory cgroup cgroup rw,nosuid,nodev,noexec,rela
| | |-/sys/fs/cgroup/devices cgroup cgroup rw,nosuid,nodev,noexec,rela
| | |-/sys/fs/cgroup/freezer cgroup cgroup rw,nosuid,nodev,noexec,rela
| | |-/sys/fs/cgroup/net_cls cgroup cgroup rw,nosuid,nodev,noexec,rela
| | |-/sys/fs/cgroup/blkio cgroup cgroup rw,nosuid,nodev,noexec,rela
| | `-/sys/fs/cgroup/perf_event cgroup cgroup rw,nosuid,nodev,noexec,rela
| |-/sys/kernel/debug debugfs debugfs rw,relatime
| `-/sys/kernel/config configfs configfs rw,relatime

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,nosuid,nodev,noexec,relatime
/sys sysfs sysfs rw,nosuid,nodev,noexec,relatime,s
/dev devtmpfs devtmpfs rw,nosuid,seclabel,size=370080k,n
/dev/pts devpts devpts rw,nosuid,noexec,relatime,seclabe
/dev/shm tmpfs tmpfs rw,nosuid,nodev,seclabel
/run tmpfs tmpfs rw,nosuid,nodev,seclabel,mode=755
/ /dev/mapper/vg_fedora-lv_root
ext4 rw,relatime,seclabel,data=ordered
/sys/kernel/security securityfs security rw,nosuid,nodev,noexec,relatime
/sys/fs/selinux selinuxfs selinuxf rw,relatime
/sys/fs/cgroup tmpfs tmpfs rw,nosuid,nodev,noexec,seclabel,m
/sys/fs/cgroup/systemd cgroup cgroup rw,nosuid,nodev,noexec,relatime,r
[output truncated]
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 -t type
For example, to all list ext4 file systems, type:
~]$ findmnt -t ext4
TARGET SOURCE FSTYPE OPTIONS
/ /dev/mapper/vg_fedora-lv_root ext4 rw,relatime,seclabel,data=ordered
/boot /dev/vda1 ext4 rw,relatime,seclabel,data=ordered
For a complete list of available command line options, refer to the findmnt(8) manual page.
