How Linux mounts a USB flash drive

Before you hang the U-disk, run the command cat/proc/partitions to see what partitions are present in the system. After inserting the U-disk, run the above command again to see what partition (usually sda1,ps because I am installed under the virtual machine, so it is SDB1).

1. Insert USB stick

2, input fdisk-l/DEV/SDA View the output results, such as mine is this:

# fdisk-l/DEV/SDA

disk/dev/sda:131 MB, 131104768 bytes

3 heads, Sectors/track, 2667 cylinders

Units = Cylinders of * 49152 bytes

Device Boot Start End Blocks Id System

/DEV/SDB1 * 1 2668 128016 6 FAT16

3, look at the above output know the device of the U disk, for example, my is/DEV/SDB1, then is mounted, assuming I will mount the USB stick to the/mnt/usb directory (no, new), is

Mount-t Msdos/dev/sdb1/mnt/usb

If it's FAT16, use the following command.

Mount-t Msdos/dev/sdb1/mnt/usb

If it's FAT32,

Mount-t Vfat/dev/sdb1/mnt/usb

In the case of the ext2 format, use the command:

Mount-t Ext2/dev/sda1/mnt/usb

4, open/mnt/usb can see your u disk in the thing!

Cd/mnt/usb

Specific commands:

1. Add-on FAT32 file system

The simplest usage

mount/dev/hda6/mnt/d

/dev/hda6 is the author of Windows D disk,/mnt/d is the directory plus hang point. Linux recognizes what the file system type of the/DEV/HDA6 partition is and then hangs it. Of course, you can also specify the file system type of the partition, with the following command:

Mount-t vfat/dev/hda6/mnt/d

In the actual operation, directly with a Windows partition, the Chinese file name and directory name will be garbled, in order to avoid this situation can specify the character set, the command is as follows:

MOUNT/DEV/HDA6/MNT/D-O codepage=936,iocharset=cp936

Mount-t vfat/dev/hda6/mnt/d-O codepage=936,iocharset=cp936

Note: cp936 refers to Simplified Chinese, cp950 refers to traditional Chinese.

2. Attach the NTFS file system

On most Linux versions today, you will need to recompile your Linux kernel to mount NTFS partitions (see other articles for compiling methods). After the core supports NTFS, you can mount it with the following command:

Mount-t ntfs/dev/hda2/mnt/c

Also for the Chinese file name and directory name will be garbled problem can specify a character set, but unlike the VFAT partition, the actual use of the command is feasible:

Mount-t Ntfs-o iocharset=cp936/dev/hda2/mnt/c-R

Mount-t Ntfs-o iocharset=cp936,rw/dev/hda2/mnt/c

3. Attach the file system on the USB drive

Now there are more and more people using USB flash drive, in fact, the use of the USB flash drive is very simple, Linux USB device has a good support, after you insert a USB stick, the U disk is recognized as a SCSI disk, usually you can use the following command to attach the file system on the USB flash drive

Mount/dev/sda1/usb

Also for Chinese filenames and directory names will be garbled problem can specify a character set, the command is similar to FAT32 described above:

Mount/dev/sda1/usb-o pagecode=936,iocharset=cp936

4. Add a directory to the Linux system shared by Samba

It's hard to say what kind of file system it is, but it doesn't matter if it's transparent to the user. When hanging, we specify the type of SMBFS, when the partition of the Samba shared, also appear in Chinese file name and directory name garbled situation, can be hung with the following command:

Mount-t Smbfs-o

username=terry,password=terry,codepage=936,iocharset=cp936

terry-linux/terry/mp3/

Mount-t Smbfs-o

username=terry,password=terry,codepage=936,iocharset=cp936

192.168.100.228/terry/mp3/

Note: You can not directly write Password=terry This parameter, the system interface will ask you to enter the password, so that you can prevent someone directly see your password. Depending on the situation, the parameters after-O can be increased or decreased.

5. Add-on Window System shared directory

In a local area network, it is often necessary to access directories shared by other Windows systems, and under Linux, after installing Samba, you can use the commands in Samba to access shared resources for Windows machines.

Use Smbclient to list shared resources for Windows machines

Smbclient-l 192.168.100.111

Depending on the shared resources of Windows listed above, you can select a shared resource that needs to be attached to Windows on your local Linux, and then use Smbmount or mount to mount it, please refer to the following several commands:

Smbmount//192.168.100.111/public/public/

Mount//192.168.100.111/d/mnt/cdrom-o Username=terry (to enter the password at the command line)

Mount//192.168.100.111/d/mnt/cdrom-o username=terry$1234 (so you don't have to enter a password at the command line)

Note: In addition to the command line method described above, the best way is to use other clients, such as Linneighborhood, networkneighbours, ksmbshare, etc., please refer to other articles.

All of the above is the command line, each use to enter once, if you often want to hang some file system, you want to automatically when the startup should be how to do? Two methods are described below:

Method 1.

Put the attached command in the/etc/rc.d/rc.local.

Method 2.

Modify the partition profile/etc/fstab, attach the file system at startup, and the following is my/etc/fstab file:

label=//ext3 Defaults

1 1

None/dev/pts devpts gid=5,mode=620

0 0

Label=/home/home ext3 Defaults

1 2

NONE/PROC proc Defaults

0 0

NONE/DEV/SHM TMPFS Defaults

0 0

/DEV/HDA4 Swap swap Defaults

0 0

/dev/cdrom/mnt/cdrom iso9660

Noauto,owner,kudzu,ro 0 0

/dev/hda2/ntfs NTFS defaults,iocharset=cp936 0 0

/dev/hda6/win vfat defaults,codepage=936,iocharset= cp936 0 0

192.168.100.228/terry/mp3 Smbfs username=terry,password=terry,codepage=cp936,iocharset=cp936 0 0

Please note the last three lines:

Bottom line Fourth, add my C drive, NTFS format

The penultimate line, plus my D-disk, FAT32 format

The second-to-last line is a directory on another Linux file server on my LAN that installs samba.

All of the above commands must be root to execute

Linux under the installation of USB drive driver

First, enter the CD/MNT directory

Fdisk-l See if a USB drive is found

Display: Extra sda1 This move is a USB drive

Two, in the MNT directory built file usb

mnt]# mkdir USB

Three, hook up

Mount/dev/sda1/mnt/usb

Four, enter the new USB

Cd/mnt/usb

ll find zone Move file

Five, enter the catalogue

CD/Driver-mounted folder

Cd/src

Make clean Empty the original file

Make install Installation
