1. Check the location of the U disk

sudo fdisk -l

According to the size of the U disk, the approximate path can be roughly determined

My output here is

Partition 2 does not start on physical sector boundary.

My USB stick is 8T, so it can be roughly judged that the last / dev/sdf1 should be my USB stick

2. mount

sudo mount U disk location target location

For example:

sudo mount /dev/sdf1 /braindat/huangwei2

3. copy

At this time, the U disk has been successfully mounted on the target location, but the contents of the U disk are not copied on the target machine. At this time, we need to execute cp to copy

But generally, the data is relatively large. If we use cp directly, we will not know how long the replication will take. If there is a progress bar, it is good

Here are two things to introduce:

The first one is tmux. See how to use tmux: A tutorial of using tmux In short, tmux is a small plug-in that divides screens and opens multiple terminals. Sometimes, on the server, we need to open multiple terminals on the same path at the same time and switch them. This requires tmux. tmux new means to create a new terminal, first press Ctrl+B, then press D to temporarily exit the terminal, etc

The second is mc. The first is installation: sudo apt get install mc. Use the tutorial: mc tutorial
