|Linux / Unix Command: mkfs|
NAMEmkfs - build a Linux file system
SYNOPSISmkfs [ -V ] [ -t fstype ] [ fs-options ] filesys [ blocks ]
DESCRIPTIONmkfs 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 system. 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.
- 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.
- -t fstype
- Specifies the type of file system to be built. If not specified, the default file system type (currently ext2) is used.
- 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.
- Check the device for bad blocks before building the file system.
- -l filename
- Read the bad blocks list from filename
- Produce verbose output.
