NAME
mkfs - construct a file system (generic)
SYNOPSIS
/usr/sbin/mkfs
[-F FStype ][-o specific_options ][
-V] special [operands ]
/usr/sbin/mkfs
[-F FStype ][-m][
-V] special
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 deter-
mined 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 subop-
tions 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 infor-
mation derived from /etc/fstab. This option allows the user to verify the com-
mand 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
