"Linux learning is not difficult" file system Management (3): Creating a file system in a Linux system

18.3 "Linux learning is not difficult" File System Management ( 3 ): In Linux creating a file system in the system

use the MKFS command to create various file systems on a partition. the MKFS command itself does not perform the work of establishing the file system, but rather calls the relevant program to execute it. The file system here is to be specified, such as xfs,ext4,ext3,vfat, or msdos .

Command syntax:

MKFS [ options ] [ devices ]

The meanings of the options in the command are as shown in the table.

options	option meaning
-t < file system type ;	Specify file system type
-V	Show more information

Example: Creating an XFS file system for a/DEV/SDA5 disk partition .

of course, you can format the disk partition into other file system types. For example, you can format /dev/sda5 as Ext4,ext3, or vfat file system types.

Example: Format the/DEV/SDA5 partition and create a ext4 file system.

[Email protected] ~]# mkfs-t EXT4/DEV/SDA5

Example: Format the/DEV/SDA5 partition and create a ext3 file system.

[Email protected] ~]# mkfs-t EXT3/DEV/SDA5

Example : format The/DEV/SDA5 partition to create the VFAT file system.

[Email protected] ~]# mkfs-t VFAT/DEV/SDA5

Notes:
You can also useMKFS.XFS,MKFS.EXT4,Mkfs.ext3,mkfs.ext2,Mkfs.msdos,Mkfs.vfatcommand to create different file systems on the disk partition.
