System administration command. Construct a filesystem on a device (such as a hard disk partition). filesys is either the name of the device or the mountpoint. mkfs is actually a frontend that invokes the appropriate version of mkfs according to a filesystem type specified by the -t option. For example, a Linux Second Extended Filesystem uses mkfs.ext2 (which is the same as mke2fs); MS-DOS filesystems use mkfs.msdos. fs-options are options specific to the filesystem type. blocks is the size of the filesystem in 1024-byte blocks.
Produce verbose output, including all commands executed to create the specific filesystem.
Tells mkfs what type of filesystem to construct.
These options must follow generic options and cannot be combined with them. Most filesystem builders support these three options:
Check for bad blocks on the device before building the filesystem.
Read the file file for the list of bad blocks on the device.
Produce verbose ouput.
