The findfs command is used to find filesystems by their label or UUID. This command is useful when you need to locate a specific filesystem on your Linux system.
Overview
The syntax for the findfs command is as follows:
findfs [OPTIONS] LABEL=LABEL/UUID=UUID
The LABEL option is used to search for a filesystem by its label, while the UUID option is used to search for a filesystem by its UUID.
Example 1: Find a filesystem by label
To find a filesystem by its label, run the following command:
findfs LABEL=mylabel
This will search for a filesystem with the label “mylabel” and return the device name.
Example 2: Find a filesystem by UUID
To find a filesystem by its UUID, run the following command:
findfs UUID=123e4567-e89b-12d3-a456-426655440000
This will search for a filesystem with the UUID “123e4567-e89b-12d3-a456-426655440000” and return the device name.
Options
The following options are available for the findfs command:
| Option | Description |
|---|---|
-V |
Display version information and exit. |
-h |
Display help information and exit. |
Troubleshooting Tips
If the findfs command does not return any results, check that the label or UUID you are searching for is correct. You can use the blkid command to list all available filesystems and their labels/UUIDs.
