UNIX learning records

As we plan to implement the project, we need some UNIX knowledge to record the learning process here ..

To tell the truth, I used to envy and worship those who operate black screens and knock out blue words. I don't have a graphical interface. It's all about character commands. I think it's awesome. In my heart, n is a worship, haha.

The original worship or image of computer people is based on these people ..

Okay, let's get started:

Step 1: Oh, of course, you do not dare to mess up files on the machine. Can you check the file?

Ls:Display file name, equivalent to dir in DOS(Well, I believe this command is the first time I learned about Unix. All the help documents or books were first introduced !)
-LShow detailed information list
-Show all files, including hidden files
-RDisplay files and all their subdirectories
-DUsed with L to display the directory name instead of content
-FDisplay file (*)

Step 2: Search for help:
Man : Get help information Man ls

Step 3: Create your own folder:
Mkdir: Create a folderMkdir yanchanggang
Step 4: Go to the created Folder:
CD:Similar to Cd in DOSCD yanchanggang
Step 4: Delete the created Folder:
Rmdir: Only folders can be deleted.First, exit to the upper-level directory CD and delete rmdir yanchanggang.
