This article mainly introduces the mkfs command how to use the relevant knowledge, detailed and easy to understand, simple and fast operation, with a certain reference value, I believe that everyone will read this mkfs command how to use the article will have some gains, let's take a look at it.

The mkfs command is used to create a Linux file system on a device, usually a hard disk. Mkfs itself does not perform the work of building the file system, but rather calls the relevant programs to do so.

Create a file system on the device

mkfs [options] device parameter

device is the name of the device on which the file system is to be created.

If the device name is in/etc/fstab, you can replace the device name with the mount point of the device, e.g./home instead of/dev/sda2

option

When running mkfs, you can specify global options or specific options for the file system type mkfs is creating (e.g. ext3, ext 4, msdos)

Global options must precede specific type options

global options

-t fstype fstype is the type of file system to create, such as ext3, ext4, etc. Different versions of Linux have different default file systems

-V Displays more output, including information about file systems

Type-specific options for file systems

The following options apply to some common file system types, ls /sbin/mkfs.* Lists programs that create file systems on local systems

$ ls /sbin/mkfs.* /sbin/mkfs.bfs /sbin/mkfs.ext3 /sbin/mkfs.minix /sbin/mkfs.vfat /sbin/mkfs.cramfs /sbin/mkfs.ext4 /sbin/mkfs.msdos /sbin/mkfs.ext2 The requested URL/sbin/mkfs.ext4dev was not found on this server.

mkfs -t

$ mkfs -t vfat /dev/sdb1 mkfs.vfat 3.0.13 (30 Jun 2012) formatted as fat32

mkfs -V -t

$ mkfs -V -t vfat /dev/sdb1 mkfs (util-linux 2.20.1) mkfs.vfat /dev/sdb1 mkfs.vfat 3.0.13 (30 Jun 2012)

Create a file system and display the message, where-V must precede-t

mkfs.vfat -v

$ mkfs.vfat -v /dev/sdb1 mkfs.vfat 3.0.13 (30 Jun 2012) Auto-selecting FAT32 for large filesystem /dev/sdb1 has 255 heads and 63 sectors per track, logical sector size is 512, using 0xf8 media descriptor, with 3887667 sectors; file system has 2 32-bit FATs and 8 sectors per cluster. FAT size is 3792 sectors, and provides 485006 clusters. There are 32 reserved sectors. Volume ID is b0f15e23, no volume label.

Create a file system with specific options and display the creation information, note that-v is lowercase here

Tips

1. Root privileges are required to create a file system

The fdisk -l command can be used to view the file system.
