How to List Mounted Drives on Linux

list mounted drive linux

In this tutorial, I will show you the different ways to list mounted drives on Linux. We can use mount, findmnt, and df commands to list mounted device any Linux distribution like Ubuntu or Centos.

In Linux, mount command mounts a storage device or filesystem, and let's go through commands that can display all those mounts.

1) Listing from /proc using cat command

To list mount points you can read contents of the file /proc/mounts.

In the following example, I have used cat command to read the /proc/mounts  file:

$ cat /proc/mounts

Output:

$ cat /proc/mounts
tmpfs /run tmpfs rw,nosuid,noexec,relatime,size=101468k,mode=755 0 0
/dev/xvda1 / ext4 rw,relatime,discard,data=ordered 0 0
debugfs /sys/kernel/debug debugfs rw,relatime 0 0
mqueue /dev/mqueue mqueue rw,relatime 0 0
hugetlbfs /dev/hugepages hugetlbfs rw,relatime 0 0
fusectl /sys/fs/fuse/connections fusectl rw,relatime 0 0
lxcfs /var/lib/lxcfs fuse.lxcfs rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other 0 0
binfmt_misc /proc/sys/fs/binfmt_misc binfmt_misc rw,relatime 0 0
tracefs /sys/kernel/debug/tracing tracefs rw,relatime 0 0
tmpfs /run/user/76547979 tmpfs rw,nosuid,nodev,relatime,size=101468k,mode=700,uid=76547979,gid=76546561 0 0
~$ cat /proc/self/mounts
tmpfs /run tmpfs rw,nosuid,noexec,relatime,size=101468k,mode=755 0 0
/dev/xvda1 / ext4 rw,relatime,discard,data=ordered 0 0
debugfs /sys/kernel/debug debugfs rw,relatime 0 0
mqueue /dev/mqueue mqueue rw,relatime 0 0
hugetlbfs /dev/hugepages hugetlbfs rw,relatime 0 0
fusectl /sys/fs/fuse/connections fusectl rw,relatime 0 0
lxcfs /var/lib/lxcfs fuse.lxcfs rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other 0 0
binfmt_misc /proc/sys/fs/binfmt_misc binfmt_misc rw,relatime 0 0
tracefs /sys/kernel/debug/tracing tracefs rw,relatime 0 0
tmpfs /run/user/76547979 tmpfs rw,nosuid,nodev,relatime,size=101468k,mode=700,uid=76547979,gid=76546561 0 0

2) Using Mount Command

You can use mount command to list mount points. When you run mount command without any options it will list mount points.

$ mount

Sample Outputs

~$ mount
tmpfs on /run type tmpfs (rw,nosuid,noexec,relatime,size=101468k,mode=755)
/dev/xvda1 on / type ext4 (rw,relatime,discard,data=ordered)
debugfs on /sys/kernel/debug type debugfs (rw,relatime)
mqueue on /dev/mqueue type mqueue (rw,relatime)
hugetlbfs on /dev/hugepages type hugetlbfs (rw,relatime)
fusectl on /sys/fs/fuse/connections type fusectl (rw,relatime)
lxcfs on /var/lib/lxcfs type fuse.lxcfs (rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,relatime)
tracefs on /sys/kernel/debug/tracing type tracefs (rw,relatime)
tmpfs on /run/user/76547979 type tmpfs (rw,nosuid,nodev,relatime,size=101468k,mode=700,uid=76547979,gid=76546561)

You may also use mount -l command which will list all mounted filesystem with labels.
$ mount -l
tmpfs on /run type tmpfs (rw,nosuid,noexec,relatime,size=101468k,mode=755)
/dev/xvda1 on / type ext4 (rw,relatime,discard,data=ordered) [cloudimg-rootfs]
systemd-1 on /proc/sys/fs/binfmt_misc type autofs (rw,relatime,fd=27,pgrp=1,timeout=0,minproto=5,maxproto=5,direct)
debugfs on /sys/kernel/debug type debugfs (rw,relatime)
mqueue on /dev/mqueue type mqueue (rw,relatime)
hugetlbfs on /dev/hugepages type hugetlbfs (rw,relatime)
fusectl on /sys/fs/fuse/connections type fusectl (rw,relatime)
lxcfs on /var/lib/lxcfs type fuse.lxcfs (rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,relatime)
tracefs on /sys/kernel/debug/tracing type tracefs (rw,relatime)
tmpfs on /run/user/76547979 type tmpfs (rw,nosuid,nodev,relatime,size=101468k,mode=700,uid=76547979,gid=76546561)

3) Using df command

You can use df command to list mount points.

The following command shows the output of df with -aTh option:

$ df -aTh

tmpfs          tmpfs        100M     0  100M   0% /run/user/76547979

You can use -t followed by filesystem type (say ext3, ext4, nfs) to display respective mount points. For examples below df command display all NFS mount points.

# df -HP -t nfs

4 ) Using findmnt

Findmnt is a powerful tool to find mounted filesystems. This command comes with lots of options to list mount filesystems.

The following command print all mounted filesystems:

$ findmnt
TARGET                                SOURCE      FSTYPE      OPTIONS
/                                     /dev/xvda1  ext4        rw,relatime,discard,data=ordered

Print mount point by specific filesystem type:

$ findmnt -t ext4
TARGET SOURCE     FSTYPE OPTIONS
/      /dev/xvda1 ext4   rw,relatime,discard,data=ordered

Search and list fstab contents:

$ findmnt -s

Display all /etc/fstab file and converts LABEL= and UUID= tags to the real device names:

$ findmnt --fstab --evaluate

Conclusion
