The labelit utility is used to write or display labels on unmounted disk file systems.

The following options are supported:

-F FSType

Specify the FSType on which to operate. The FSType should either be specified here or be determinable from /etc/vfstab by matching the special with an entry in the table. If no matching entry is found, the default file system type specified in /etc/default/fs will be used.

-V

Echo complete command line. This option may be used to verify and validate the command line. Additional information obtained using a /etc/vfstab lookup is included in the output. The command is not executed.

-o

Specify FSType-specific options. See the manual page for the labelit module specific to the file system type.

The following operands are supported. If no operands are specified, labelit will display the value of the labels.

special

The disk partition (for example, /dev/rdsk/c0t3d0s6). The device may not be on a remote machine.

operands

FSType-specific operands. Consult the manual page of the FSType-specific labelit command for detailed descriptions.

See largefile(5) for the description of the behavior of labelit when encountering files greater than or equal to 2 Gbyte ( 2³¹ bytes).

The following exit values are returned:

0

Write or display of labels was successful.

non-zero

An error occurred.

/etc/vfstab

List of default parameters for each file system.

/etc/default/fs

Default local file system type. Default values can be set for the following flags in /etc/default/fs. For example:

LOCAL=ufs

LOCAL

The default partition for a command if no FSType is specified.

See attributes(5) for descriptions of the following attributes:

labelit_hsfs(1M), labelit_udfs(1M), labelit_ufs(1M), volcopy(1M), vfstab(4), attributes(5), largefile(5)

This utility may not be supported for all FSTypes.
