The clear command is used to clear the terminal screen, similar to the "cls" command in DOS. It effectively hides all previously executed commands and their output, giving you a clean and empty terminal window. This can be especially useful when your terminal becomes cluttered with a lot of output and you want to start with a fresh, clear screen.
The clear command doesn't require any arguments or options. You simply need to type clear in the terminal and press Enter.
Here's an example:| $ echo "Hello World!" ← display〝Hello World!〞 Hello World! $ clear ←clear the terminal screen |
Sometimes, the clear command might not be able to clear the screen completely. In such cases, you can use the reset command to reset the screen.
