I personally mount the file as follows:

Run the following command twice before and after inserting a USB flash drive:

# Fdisk-l

After the USB flash drive is inserted, run the fdisk-l command again to find that the content in the red box is added, that is, the size of the device/dev/sdb4 is 30277505, which is equivalent to 28.4 GB, it can be determined that I have a 32-bit USB flash drive:

Create a directory in the/mnt directory as a mount point:

# Cd/mnt # mkdir usb-fat32

Mount a USB flash drive in fat32 format:

# Mount-t vfat/dev/sdb4/mnt/usb-fat32

In case of garbled characters in the USB flash drive file, you can mount the file as follows:

# Mount-t vfat-o iocharset = cp936/dev/sdb4/mnt/usb-fat32

Now you can view the files in the USB flash drive:

# Ls, mnt, usb-fat32

You can detach a USB flash drive:

# Umount/mnt/usb-fat32

Or

# Umount/dev/sdb4
