E2LABEL(8)                                                    System Manager's Manual                                                   E2LABEL(8)

NAME

       e2label - Change the label on an ext2/ext3/ext4 filesystem

SYNOPSIS

       e2label device [ volume-label ]

DESCRIPTION

       e2label will display or change the volume label on the ext2, ext3, or ext4 filesystem 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.

       It is also possible to set the volume label using the -L option of tune2fs(8).

AUTHOR

       e2label was written by Theodore Ts'o (tytso@mit.edu).

AVAILABILITY

       e2label is part of the e2fsprogs package and is available from http://e2fsprogs.sourceforge.net.
