Manual page and help for the mkfs.btrfs linux command. You can use mkfs.btrfs to create a btrfs file system on one or more devices (usually a disk partition). The "device" parameter is a special file that specifies access to the device under operation (eg / dev / sdXX). Several devices are grouped based on the UUID of the file system. Before mounting such a filesystem, the kernel module must already know all the devices before performing a device scan of the btrfs filesystem.

Manual page and help for the mkfs.minix linux command. You can use mkfs.minix to create a Linux MINIX file system on a device (usually a disk partition). The "device" parameter is a special file that specifies access to the device under operation (eg / dev / sdXX). Must be entered. Use the "size-in-blocks" parameter to specify the desired file system size. This parameter is only present for backward compatibility. If this parameter is not specified, the file system size is determined automatically. If specified, the value must be between 10 and 65536.

Manual page and help for the mkfs.cramfs linux command. The files in the cramfs file system are compressed with zlib, one at a time, for random access. Metadata is not compressed, but is created with a short representation, making it more space-saving than traditional file systems. The file system is intentionally read-only to keep it simpler to design; random write access to compressed files is difficult to implement. Cramfs has a utility (mkcramfs) that compresses the files into new cramfs image files. File sizes are limited to 16 MB. The maximum file system size must be less than 272 MB. (The last file in the file system must start before the 256 MB block, but you can extend it.)

Manual page and help for the mkfs.bfs linux command. You can use mkfs.bfs to create an SCO bfs file system on a block device (usually a disk partition). The "device" parameter is a special file that specifies access to the device under operation (eg / dev / sdXX). Must be entered. The "block-count" option allows you to specify the number of blocks on the device. If you leave, mkfs.bfs will use the entire partition.

Manual page and help for the mkfs.exfat and mkexfatfs linux commands. The mkfs.exfat / mkexfatfs command creates an exFAT file system on a block device. The "device" parameter is a special file that specifies the access to the device under operation (eg / dev / sdXX). Must be entered. Note that if this is an MBR partition, the file system type must be set to 0x07 (NTFS / exFAT), otherwise other operating systems may refuse to mount the file system.

Manual page and help for the mkfs.ntfs and mkntfs linux commands. You can use mkfs.ntfs or mkntfs to create an NTFS file system under Linux on a device (usually a disk partition). The "DEVICE" parameter is a special file that specifies access to the device under operation (eg / dev / sdXX). Must be entered. The "number-of-sectors" option allows you to specify the number of sectors on the device. When you leave, mkfs.ntfs / mkntfs automatically determines the size of the file system.

Manual page and help for the mkfs.fat linux command. You can use mkfs.fat to create an MS-DOS file system under Linux on a device (usually a disk partition). The "DEVICE" parameter is a special file that specifies access to the device under operation (eg / dev / sdXX). Must be entered. The "BLOCK-COUNT" option allows you to specify the number of blocks on the device. When you leave, mkfs.fat automatically determines the size of the file system.

The manual page and help for the mkfs linux command. Mkfs builds a Linux file system on a device, usually on a hard disk partition.
