Linux Tutorial: mount command: how to mount an external storage medium in Linux

When using a CD, floppy disk, or USB flash disk in Linux, you must run the mount command first. The mount command will specify these storage media as a directory in the system, and then directly access the corresponding directory to read and write data on the storage media.

1. Attach a cd

The command for attaching a CD is as follows:

# Mount-T is09660/dev/CDROM/mnt/CDROM

This command mounts the disc to the/mnt/CDROM directory, and uses the "ls/mnt/CDROM" command to display the data and files on the disc.

The command for detaching a CD is as follows:

# Umount/mnt/CDROM

2. mount a floppy disk

Run the following command to mount a floppy disk to the/mnt/Floppy directory:

# Mount/dev/fd0/mnt/floppy

The command to detach a floppy disk is as follows:

# Umount/mnt/floppy

3. attaching a USB flash disk is relatively complicated.

First, run the "fdisk-L" command to view the device Number of the plug-in flash memory, which is generally/dev/sda1. Then run the "mkdir/mnt/USB" command to create a directory for mounting the USB disk. Run the following command to mount the fat format USB flash drive:

# Mount-T msdos/dev/sda1/mnt/USB

Run the following command to mount a USB flash drive in FAT32 format:

# Mount-T vfat/dev/sda1/mnt/USB

4. Mount external hard disk partitions

To mount the external hard disk partition (FAT32 format), you also need to use "fdisk-1" to view the device Number of the external hard disk partition, which is assumed to be/dev/hda1. Run the following command to mount the/mnt/vfat Mount directory:

# Mount-T vfat/dev/hda1/mnt/vfat

Note: by default, Linux only allows the root user to execute the mount command. To enable general users to mount the disk or floppy disk automatically when the system starts, modify the/etc/fstab configuration file and add the following content:

Label = // ext3 defaults 11/dev/CDROM/mnt/CDROM iso9660 auto, owner, kudzu, Ro, user 00/dev/fdo/mnt/Floppy auto, owner, kudzu, Ro, user 00

"User" indicates that the mount command is assigned to a general user.

The/etc/fstab file is detailed in the Linux help manual. You may wish to take a look.
