Mount a USB flash drive in Linux and unmount the USB flash drive: 1. After inserting the USB flash drive, enter fdisk-l or fdisk-l/dev/sdb on the Linux terminal, (view the hard disk and partition information) as follows, it indicates that the device has been identified and its name is sdb1. 2. Create a mount directory # mkdir/mnt/usb 3 to mount the usb flash drive to the/mnt/usb directory. The mount command format is as follows: mount [-parameter] [device name] [mount point] [other parameters] mount-t vfat/dev/sdb1 // mnt/usb-o iocharset = gb2312-t specifies the device's file System type, here, the-t vfat is used because the file system type of the U disk is fat32, and-t ntfs is used for ntfs. You can flexibly modify it according to your file system type. -O specifies the option for mounting the file system. Here,-o iocharset = gb2312 sets the Chinese character set. Assuming that your locale is a zh_CN.UTF-8, the corresponding command should be-o iocharset = utf8. The usb flash disk is mounted successfully, so that you can view the content of the usb flash disk in the/mnt/usb directory. 4. The U disk unmount command umount/mnt/usb can detach the U disk from the specified directory. Note that when detaching a USB flash drive, the terminal must exit from the Mount directory of the current USB flash drive; otherwise, the user is busy.
