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).

NAME

       getvol - verifies device accessibility

SYNOPSIS

       /usr/bin/getvol -n [-l label] device

       /usr/bin/getvol [-f | -F] [-ow] [-l label | -x label] device

DESCRIPTION

       getvol  verifies  that  the  specified  device  is accessible and that a volume of the appropriate medium has been inserted. The command is
       interactive and displays instructional prompts, describes errors, and shows required label information.

OPTIONS

       The following options are supported:

       -n	   Runs the command in non-interactive mode. The volume is assumed to be inserted upon command invocation.

       -l label    Specifies that the label  label must exist on the inserted volume (can be overridden by the -o option).

       -f	   Formats the volume after insertion, using the format command defined for this device in the device table.

       -F	   Formats the volume after insertion and places a file system on the device. Also uses the format command defined for this device
		   in the device table.

       -o	   Allows the administrator to override a label check.

       -w	   Allows  administrator to write a new label on the device. User is prompted to supply the label text. This option is ineffective
		   if the  -n option is enabled.

       -x label    Specifies that the label  label must exist on the device. This option should be used in place of the  -l option when the  label
		   can	only  be verified by visual means. Use of the option causes a message to be displayed asking the administrator to visually
		   verify that the label is indeed  label.

OPERANDS

       The following operands are supported:

       device	 Specifies the device to be verified for accessibility.

EXIT STATUS

       The following exit values are returned:

       0    Successful completion.

       1    Command syntax was incorrect, invalid option was used, or an internal error occurred.

       3    Device table could not be opened for reading.

NOTES

       This command uses the device table to determine the characteristics of the device when performing the volume label checking.
