List all mount linux

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% /

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.

How to get the complete and exact list of mounted filesystems in Linux?

I usually use mount to check which filesystems are mounted. I also know there is some connection between mount and /etc/mtab but I’m not sure about the details. After reading How to check if /proc/ is mounted I get more confused. My question is: How to get the most precise list of mounted filesystems? Should I just use mount , or read the contents of /etc/mtab , or contents of /proc/mounts ? What would give the most trustworthy result?

I can’t help linking to What is /etc/mtab in Linux? because it covers non-Linux details that none of the answers here give.

The definitive list of mounted filesystems is in /proc/mounts .

If you have any form of containers on your system, /proc/mounts only lists the filesystems that are in your present container. For example, in a chroot, /proc/mounts lists only the filesystems whose mount point is within the chroot. (There are ways to escape the chroot, mind.)

There’s also a list of mounted filesystems in /etc/mtab . This list is maintained by the mount and umount commands. That means that if you don’t use these commands (which is pretty rare), your action (mount or unmount) won’t be recorded. In practice, it’s mostly in a chroot that you’ll find /etc/mtab files that differ wildly from the state of the system. Also, mounts performed in the chroot will be reflected in the chroot’s /etc/mtab but not in the main /etc/mtab . Actions performed while /etc/mtab is on a read-only filesystem are also not recorded there.

The reason why you’d sometimes want to consult /etc/mtab in preference to or in addition to /proc/mounts is that because it has access to the mount command line, it’s sometimes able to present information in a way that’s easier to understand; for example you see mount options as requested (whereas /proc/mounts lists the mount and kernel defaults as well), and bind mounts appear as such in /etc/mtab .

Linux command to list file systems available for mounting?

What terminal command will return data that includes the file systems that are currently available for mounting on my system? Specifically, I am using Ubuntu 15.04, though I would prefer an answer that is valid for all *nix users. NOTES: I don’t want to know what IS mounted, I want to know what is available. I don’t want to check the type of file system (ext2, ext4, ntsf, etc.), I want to know which file systems are available to be mounted (sda2, fd1, etc.).

Do you mean which filesystems (e.g, ext4, xfs, tmpfs) are available, or what disk devices which potentially contain filesystems (e.g, sdb1, sdd3) are available?

@duskwuff No, I do not mean file system TYPES (ext4, etc.), I mean file systems (which are formatted to a type). Please see CompTIA for clarification of the terms.

What you are describing sounds like storage devices, not file systems. If CompTIA uses the phrase «file systems» to describe this, I’m sorry, but they are wrong.

On Ubuntu you can use to show discs:

or to check all partitions on your system

sudo blkid -o list | grep "not mounted" 

or if you just want the device:

sudo blkid -o list | grep "not mounted" | awk '' 

Just to point out, since you edited, the command sudo blkid -o list | grep «not mounted» is the one that was correct.

Regarding the question «command will return data that includes the file systems that are currently available for mounting on my system».

Granted from the powerful PROC file system, the available (or, static + dynamically installed) file systems in a running Linux could be found by:

In my linux 3.10.0, the result is:

$cat /proc/filesystems nodev sysfs nodev rootfs nodev ramfs nodev bdev nodev proc nodev cgroup nodev cpuset nodev tmpfs nodev devtmpfs nodev debugfs nodev securityfs nodev sockfs nodev dax nodev bpf nodev pipefs nodev configfs nodev devpts nodev hugetlbfs nodev autofs nodev pstore . 

This is the meta-data, the «mount» command will find and use.

Then, with below command, it lists all the mounted file systems.

$cat /proc/mounts /dev/sda1 /boot xfs rw,relatime,attr2,inode64,noquota 0 0 . cgroup /sys/fs/cgroup/devices cgroup rw,nosuid,nodev,noexec,relatime,devices 0 0 

The third field of each line, like xfs or cgroup, is the «file system», which is just mentioned in previous command.
