Which command is used to change the label on the filesystem in Linux?

The command used to change the label on the filesystem in Linux is e2label. This command specifically is designed to work with ext2, ext3, and ext4 filesystems, allowing users to set or change labels that help identify a filesystem. Labels can be particularly useful for organizing and identifying disk partitions, especially when multiple filesystems are present.

In contrast, resize2fs is used to resize ext2, ext3, and ext4 filesystems, allowing for adjustments in the size of the filesystem but not for changing its label. The mount command is used to attach filesystems to the system’s directory structure, enabling access to the data stored on them, while umount is the command used to detach or unmount filesystems from the directory structure. Neither of these commands has functionality related to changing filesystem labels. Therefore, e2label is the appropriate tool for managing filesystem labels in a Linux environment.
