Linux show mounted devices

How do I check where devices are mounted?

What is the command that lets me see what and where devices are mounted? I’m having trouble changing songs on my old iPod, and I have a feeling it’s because of the mount point.

There are at least three programs I know of that list device mount points:

mount — mount a filesystem (used for general mount info too):

$ mount /dev/sda3 on / type ext4 (rw,errors=remount-ro) proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) . /dev/mapper/lvmg-homelvm on /home type btrfs (rw,relatime,compress=lzo,space_cache) /dev/sda5 on /home/muru/arch type btrfs (rw,relatime,compress=lzo,space_cache) binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev) systemd on /sys/fs/cgroup/systemd type cgroup (rw,noexec,nosuid,nodev,none,name=systemd) 

$ df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda3 30832636 11993480 17249912 42% / none 4 0 4 0% /sys/fs/cgroup . /dev/sda5 31457280 3948600 25396496 14% /home/bro3886/arch 

$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 465.8G 0 disk ├─sda1 8:1 0 100M 0 part ├─sda2 8:2 0 58.5G 0 part ├─sda3 8:3 0 30G 0 part / ├─sda4 8:4 0 1K 0 part ├─sda5 8:5 0 30G 0 part ├─sda6 8:6 0 339.2G 0 part │ └─lvmg-homelvm (dm-0) 252:0 0 1.2T 0 lvm └─sda7 8:7 0 8G 0 part [SWAP] sdb 8:16 0 931.5G 0 disk └─sdb1 8:17 0 931.5G 0 part └─lvmg-homelvm (dm-0) 252:0 0 1.2T 0 lvm 

Of these three, mount lists all the mountpoints, AFAICT. The others have their weaknesses.

findmnt suggested by @webwurst is now my favourite tool for the job. It’s a Swiss Army knife when it comes to output control (newer versions can output in JSON too):

$ findmnt / TARGET SOURCE FSTYPE OPTIONS / /dev/sda1 ext4 rw,relatime,errors=remount-ro,data=ordered $ findmnt / -no source /dev/sda1 $ findmnt / --json < "filesystems": [ ] > $ findmnt / --df SOURCE FSTYPE SIZE USED AVAIL USE% TARGET /dev/sda1 ext4 40.2G 25.8G 12.5G 64% /

How to show mounted devices in Linux?

mount have many exciting options (see man mount). In our case, we will only use -l which adds the labels in the mount output.

4 Ways to Show all Drives (Mounted and Unmounted) on Linux

The drives on any system can either be mounted or unmounted. The mounted drives are the ones that are ready to be accessed at any time whereas the data residing on the unmounted drives can only be accessed after these drives are mounted. In the proceeding section of this article, we want to share with you the different methods of displaying all available drives on Linux.

Display all Drives on Linux

To display all of your drives on a Linux system, you can perform any of the following four methods:

Method # 1: Using the “fdisk” Command

The “fdisk” command can be used to display the drives in Linux in the manner shown below:

The output produced by this command is shown in the following image:

Method # 2: Using the “blkid” Command:

The “blkid” command can be used to display available drives in Linux in the manner shown below:

The output produced by this command is shown in the following image:

Method # 3: Using the “lsblk” Command:

The “lsblk” command can be used to display the system drives in Linux in the manner shown below:

The output produced by this command is shown in the following image:

Method # 4: Using the “parted” Command:

The “parted” command can be used to display the disk partitions in Linux in the manner shown below:

The output produced by this command is shown in the following image:

Conclusion

By picking out any of the four methods shared in this article, you can conveniently find out all the mounted and unmounted drives on your Ubuntu system. Once you have this information, you can always mount a drive out of these whenever you wish to access its contents.

4 Commands to List Mounted File Systems in Linux

The Linux operating system provides multiple filesystems, including ext4, xfs, tmpfs, securityfs, and many more. This guide demonstrates various ways to list all mounted file systems in a Linux system.

1. View Linux Mounted Filesystem Using /proc Filesystem

The /proc/mounts file is a file that displays the status of all filesystems that are currently mounted on the system. The file format closely resembles that of the /etc/fstab file. The file reports the status of mounted filesystems as recorded by the Linux kernel.

Thus, to view all the mounted filesystems, view the /proc/mounts file using the cat command as shown.

2. List Linux Mounted Filesystem Using df Command

The df command is mostly used to check disk space utilization on mounted file systems. It lists, among other statistics, total disk space and available disk space on each mounted filesystem.

When the -a option is included, the df command lists all the mounted filesystems.

3. Print Linux Mounted Filesystems Using findmnt Command

The findmnt command is yet another powerful command that displays all mounted filesystems on your Linux system in a tree-like format.

To print all the mounted filesystems, simply run the command without any arguments.

This prints the output in a tree-like format as shown.

You can pass the -D option which will print the output similar to the df -Th command

Pass the -t option followed by the filesystem type to print specific filesystems. For example, to view all the mounted EXT4 filesystems, run the command:

To view all EXT4 filesystems mounted in the /etc/fstab file, run the command:

4. Show Mounted Linux Filesystem Using mount Command

You can also use the mount command to list all mounted file systems. Without any arguments, it lists all the mounted filesystems.

Summing Up

In this guide, we have explored four ways that you can use to list all mounted file systems in a Linux system. Your views and feedback on this guide are welcome.
