mkfs is used to build a Linux filesystem on a device, usually a hard disk partition. The device argument is either the device name (e.g. /dev/hda1, /dev/sdb2), or a regular file that shall contain the filesystem. The size argument is the number of blocks to be used for the filesystem.
The exit code returned by mkfs is 0 on success and 1 on failure.
In actuality, mkfs is simply a front-end for the various filesystem builders (mkfs.fstype) available under Linux. The filesystem-specific builder is searched for via your PATH environment setting only. Please see the filesystem-specific builder manual pages for further details.
- -t, --type type
- Specify the type of filesystem to be built. If not specified, the default filesystem type (currently ext2) is used.
- Filesystem-specific options to be passed to the real filesystem builder.
- -V, --verbose
- Produce verbose output, including all filesystem-specific commands that are executed. Specifying this option more than once inhibits execution of any filesystem-specific commands. This is really only useful for testing.
- -V, --version
- Display version information and exit. (Option -V will display version information only when it is the only parameter, otherwise it will work as --verbose.)
- -h, --help
- Display help text and exit.

The manual page was shamelessly adapted from Remy Card's version for the ext2 filesystem.
