In the DOS operation interface of windows, clear the screen The command is cls, so what is the clear screen command in Linux? Here are some ways to clear the screen under Linux.

1. clear command. This command will refresh the screen. Essentially, it just turns the terminal display page back one page. If you scroll up the screen, you can also see the previous operation information. .

2. Ctrl l (lowercase L), this is a shortcut key to clear the screen. This is the screen clearing method that I use most in my work. The screen clearing effect is Same as clear command.

3. Reset command. This command will completely refresh the terminal screen. All the previous terminal input operation information will be cleared. Although it is relatively refreshing, the entire command process is a bit slow. Use less.

It is worth mentioning that the reset command is very useful when your terminal control is disordered. For example, the input characters do not appear at the cursor position. Also, when you hit the Enter key, the new prompt does not appear on a new line, but appears in front of the old prompt. At this point the reset command can be used to correct these problems.

Here are some terminal shortcut keys:

1. Tab

This is the Linux shortcut key you can’t live without. It will save you a lot of time in the Linux command line.

Just enter a command, file name, directory name or even the beginning of a command option and hit the tab key. It will automatically complete what you type or show you all possible results.

If you only remember one shortcut key, this will be the one you must choose.

2. Ctrl C

These are the keys you press to interrupt a command or process on the terminal. It will immediately terminate the running program.

If you want to stop using a running program, just press this key combination.

3. Ctrl Z

This shortcut key sends the running program to the background. Normally, you can do this before running the program with the & option, but if you forget to run the program with the & option, use this key combination.

4. Ctrl D

This pair of keyboard shortcuts will exit the current terminal. If you connect using SSH, it will be closed. If you use a terminal directly, the application will close immediately.

Think of it as the "exit" command.

5. Ctrl L

How do you clear your terminal screen? I guess it's with the clear command.

You can use Ctrl L to clear the terminal instead of typing C-L-E-A-R. Handy, isn't it?

6. Ctrl A

This shortcut key will move the cursor to the beginning of the line.

Suppose you enter a long command or path in the terminal, and you want to go back to the beginning of it, using the arrow keys to move the cursor will take a lot of time. Note that you cannot use the mouse to move the cursor to the beginning of the line.

This is where Ctrl A saves time.

7. Ctrl E

This pair of shortcut keys is the opposite of Ctrl A. Ctrl A moves the cursor to the beginning of the line, whereas Ctrl E moves the cursor to the end of the line.

8. Ctrl U

Entered the wrong command? Instead of using the backspace key to discard the current command, use the Ctrl U shortcut in the Linux terminal. This shortcut will erase everything from the current cursor position to the beginning of the line.

9. Ctrl K

This pair is somewhat similar to the Ctrl U shortcut key. The only difference is that instead of the beginning of the line, it erases everything from the current cursor position to the end of the line.

10. Ctrl W

You just learned about erasing text to the beginning and end of a line. But what if you just need to delete a word? Use the Ctrl W shortcut key.

Using the Ctrl W shortcut key, you can erase the word before the cursor position. If the cursor is on a word itself, it will erase all letters from the cursor position to the beginning of the word.

The best way is to use it to move the cursor to a space after the word you want to delete, and then use the Ctrl W keyboard shortcut.

11. Ctrl Y

This will paste the text that was erased using the Ctrl W, Ctrl U and Ctrl K shortcuts. This will come in handy if you deleted the wrong text or need to use the erased text somewhere.

12. Ctrl P

You can use this shortcut key to view the previous command. You can press this key repeatedly to return to the command history. In many terminals, the PgUp key is used to perform the same function.

13. Ctrl N

You can use this shortcut key in conjunction with Ctrl P. Ctrl N displays the next command. If you used Ctrl P to view the previous command, you can use Ctrl N to navigate back and forth. Many terminals map this shortcut to the PgDn key.

14. Ctrl R

You can use this shortcut key to search historical commands.
