labelit - list or provide labels for file systems
labelit [-F FSType] [-V] [-o FSType-specific-options] special
[operands]
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(7) for the description of the behavior of
labelit when encountering files greater than or equal to 2 Gbyte (
2^31 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.
This utility may not be supported for all FSTypes.
