Viewing File System Mount Information

WARNING:

This documentation is a draft and is not meant for production use. Branch: OL10-FSADMIN

The findmnt command provides a single tool that can be used to provide tabulated and structured information about all file systems that are mounted on a system.

The following examples show how to use the findmnt command. You can find out more information in the findmnt(8) manual page.

List all mounted file systems.
```
findmnt
```
By default, findmnt shows all the mounted file systems that are visible to the kernel in /proc/self/mountinfo. You can run findmnt -m to search the system mtab, or findmnt -s to limit the search to entries in the system fstab.
Provide disk space usage information for file system mounts.
```
findmnt -D
```
Output is formatted similarly to the output that you can get from running df -H and excludes pseudo file systems such as procfs and sysfs.
Limit file system listings by file system type.
Limit information to file systems matching particular file system types by using the --types option. For example, you can run:
```
findmnt --types xfs,ext4,btrfs,vfat
```
Return the file system information for a particular mount point.
```
findmnt /home
```
Show selected output fields.
Use the -o option to control the different output fields that are shown in a listing. For example, you can run:
```
findmnt -o TARGET,UUID,FSTYPE,OPTIONS,USE% /home
```
