e2label - Change the label on an ext2/ext3/ext4 file system
e2label device [ volume-label
]
e2label will display or change the volume label on
the ext2, ext3, or ext4 file system located on device.
If the optional argument volume-label is not present,
e2label will simply display the current volume
label.
If the optional argument volume-label is present, then
e2label will set the volume label to be
volume-label. Ext2 volume labels can be at most 16 characters
long; if volume-label is longer than 16 characters,
e2label will truncate it and print a warning message.
For other file systems that support online label manipulation and are
mounted e2label will work as well, but it will not
attempt to truncate the volume-label at all.
It is also possible to set the volume label using the -L option of tune2fs(8).
