mkfs

NAME

mkfs - build a Linux file system

SYNOPSIS

mkfs [ -V ] [ -t fstype ] [ fs-options ] filesys [ blocks ]

DESCRIPTION

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. R /dev/hda1 , R /dev/sdb2 ). 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 R /sbin , R /sbin/fs , R /sbin/fs.d , R /etc/fs , /etc (the precise list is defined at compile time but at least contains /sbin and R /sbin/fs ), and finally in the directories listed in the PATH environment variable. Please see the file system-specific builder manual pages for further details.

OPTIONS

-V
Produce verbose output, including all file system-specific commands that are executed. Specifying this option more than once inhibits execution of any file system-specific commands. This is really only useful for testing.
I -t  fstype
Specifies the type of file system to be built. If not specified, the default file system type (currently ext2) is used.
fs-options
File system-specific options to be passed to the real file system 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.
I -l  filename
Read the bad blocks list from filename
-v
Produce verbose output.

BUGS

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.
