The clear of the Linux command I used-clear the terminal screen, not the CLS

Description of Use

The clear command is used to clear the terminal screen (clear the terminal screens), people who have used DOS or Windows cmd know that there is a CLS command that can be used to clear the screen, but there is no command under Linux, We can make the Linux system also have this CLS command by using aliases. In addition, press CTRL+L can also achieve the same effect, when we use Vi/vim to edit the file, if the screen display is a bit confusing, you can also press Ctrl+l to make the screen display back to normal.

Common parameters

No.

If you want the input CLS to clear the screen, add a line at the end of the/etc/profile:

Alias Cls=clear

You can enter the CLS to achieve the clear command when you log in again after saving.

Of course, the quicker way is to hold down the CTRL key and then press L again.
