DESCRIPTION
The
mkfs
command creates a file system by writing on the special file
special.
operands
are listed on file-system-specific manpages (see the
SEE ALSO
section).
Options
mkfs
recognizes the following options:
- -F FStype
Specify the file system type on which to operate (see
fstyp(1M)
and
fs_wrapper(5)).
If this option is not included on the command line,
then the file system type is determined from the file
/etc/fstab
by matching
special
with an entry in that file.
If there is no entry in
/etc/fstab,
then the file system type is determined from the file
/etc/default/fs.
- -m
Display the command line that was used to create the file system.
The file system must already exist.
This option provides a means of determining the parameters
used to construct the file system.
- -o specific_options
Specify options specific to the file system type.
specific_options
is a list of suboptions and/or keyword/attribute pairs
intended for an
FStype-specific
module of the command.
See the file system specific manual entries for a description of the
specific_options
that are supported, if any.
- -V
Echo the completed command line, but perform no other action.
The command line is generated
by incorporating the specified options and arguments
with other information derived from
/etc/fstab.
This option allows the user to verify the command line.
EXAMPLES
Execute the
mkfs
command to create a 32MB HFS file system on
/dev/dsk/c1t2d0:
mkfs -F hfs /dev/dsk/c1t2d0 32768
Execute the
mkfs
command on an HFS file system,
/dev/dsk/c1t2d0,
to recreate the command that was used to create the file system on
/dev/dsk/c1t2d0:
mkfs -F hfs -m /dev/dsk/c1t2d0
