Copy files from an external USB drive to Linux (Mount)

The first step:

Plug the USB stick into your computer and it will react in Linux, like SDA, SDB ..., then go to the/dev directory to see if this file is available

Step Two:

Create a new directory:/mnt/mine

Step Three:

Mount the U disk under/mnt/mine: Mount/dev/sdb/mnt/mine

Fourth Step:

To see if the mount succeeds: df-h, see if there is/mnt/mine

Fifth Step:

If the mount succeeds, the data in the U-disk is all in/mnt/mine.

Sixth step:

Use the CP-RP command, you can cross-copy, you are done!
