What is the clear command?
The clear command is a basic Unix computer operating system command for cleaning the terminal screen.
This command first searches the environment for a terminal type, then explores the terminfo database for information on cleaning the screen.
Besides that, any command-line options that may be present will be ignored by this command. Furthermore, this command does not accept any arguments.
This command was developed by the Computer Systems Research Group.

If a user cleaned the terminal but wants to see the previous command they can use the history command. It means this Linux command doesn’t delete the previous command.
