mkfs - build a Linux file system
mkfs [ -V ] [ -t fstype ] [ fs-options ] filesys [ blocks ]
mkfs is used to build a Linux file system on a device, usually a hard
disk partition. filesys is either the device name (e.g. /dev/hda1,
/dev/sdb2) or the mount point (e.g. /, /usr, /home) for the file sys
tem. blocks is the number of blocks to be used for the file system.
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 file system
builders (mkfs.fstype) available under Linux. The file system-specific
builder is searched for in a number of directories like perhaps /sbin,
/sbin/fs, /sbin/fs.d, /etc/fs, /etc (the precise list is defined at
compile time but at least contains /sbin and /sbin/fs), and finally in
the directories listed in the PATH enviroment variable. Please see the
file system-specific builder manual pages for further details.
-V Produce verbose output, including all file system-specific com
mands that are executed. Specifying this option more than once
inhibits execution of any file system-specific commands. This
is really only useful for testing.
Specifies the type of file system to be built. If not speci
fied, the default file system type (currently ext2) is used.
File system-specific options to be passed to the real file sys
tem builder. Although not guaranteed, the following options are
supported by most file system builders.
-c Check the device for bad blocks before building the file system.
Read the bad blocks list from filename
-v Produce verbose output.
All generic options must precede and not be combined with file system-
specific options. Some file system-specific programs do not support
the -v (verbose) option, nor return meaningful exit codes. Also, some
file system-specific programs do not automatically detect the device
size and require the blocks parameter to be specified.
