I have re-learned Linux-general Linux technology-Linux technology and application information. The following is a detailed description. I haven't played linux for a few years.
Start learning again and find that everything is almost forgotten.
Record it.

The first command used is:
Sudo apt-get dist-upgrade
Used to upgrade the system.
The second command:
Sudo apt-get install ssh
Install remote control
You can use putty to control the client Win.
This can be said to be the only thing I remember when I learned linux.
Updating takes a long time. You can use the shortcut key Ctrl + C to interrupt command execution.
Resumable upload is performed when a new update is made.

Putty requires some settings Because Ubuntu uses the character set of UTF-8 by default:
Choose Windows on the left> Appearance to Set Font settings, and click Change... to select or.
Click Windows on the left-> Translation set Character set translation to UTF-8
