Mount command

The Linux file system combines all the media disks into a virtual directory. Before using the new media disk, you need to put it in a virtual directory. This task is called mounting!

Mount command: used to mount media

[[Email protected] ~] # Mount

/Dev/mapper/VolGroup00-LogVol00 on/type ext3 (rw)

Proc on/proc type proc (rw)

Sysfs on/sys type sysfs (rw)

Devpts on/dev/pts type devpts (rw, gid = 5, mode = 620)

/Dev/sda1 on/boot type ext3 (rw)

Tmpfs on/dev/shm type tmpfs (rw)

None on/proc/sys/fs/binfmt_misc type binfmt_misc (rw)

Sunrpc on/var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)

The mount Command provides four messages:

1. Device location of the media

2. Mount point of the media in the virtual directory

3. File system type

4. Access Status of mounted Media

Vfat: windows persistent file system (USB)

Ntfs: windows Advanced File system

ISO: Standard CD-ROM file system (CD)

For example, manually mount the USB on the device/dev/sdb1 to the/media/disk location.

Mount-t vfat/dev/sdb1/mdeia/disk

Parameters	Description
-	Mount all the file systems specified in the/etc/fstab file
-F	Use the mount command to simulate mounting a device.
-F	When connected to the-a parameter, all file systems are mounted at the same time.
-V	Detailed mode: describes the steps required to attach a device
-I	Do not use any file system help in/sbin/mount. filesystem
-L	Automatically add tags for ext2, ext3, and xfs file systems
-N	Mount the device, but not register it in the/etc/mstab mount device file
-P num	For encrypted mounting, passphrase is read from the file descriptor num.
-S	Ignore mounting options not supported by the file system
-R	Mount devices in read-only mode
-W	Mount devices in read/write mode
-L label	Mount the device with the specified label
-U uuid	Mount the device with the specified uuid
-0	When connected to the-a parameter, restrict the use of the file system set

The-o option allows you to mount a file system with a comma-separated option. Common options include:

Ro: Read-only mounting

Rw: read/write mounting

User: allows common users to Mount file systems.

Check = none: Mount the file system without performing the integrity check.

Loop: Mount a file

Mount the. iso file to the virtual directory:

[[Email protected] mnt] # mount-t iso9660-o loop file name mnt

Loop device is a virtual block device formed by shadow normal files on the operating system.

Umount command

Remove a removable media device. You should not simply remove it from the system, but uninstall it first! In linux, the mounted CD is not allowed to pop up!

Umount [directory | device]

[[Email protected] mnt] # umount/home/ley/mnt
