Clear the screen.
Syntax CLS
If CLS is redirected to file, console or executed through FOR /F it will print a line feed character (ASCII 10).
If the screen is successfully cleared %ERRORLEVEL% will be unchanged, typically this will be 0 but if a previous command set an errorlevel, that will be preserved (this is a bug).
If a bad switch is given %ERRORLEVEL% ➞ 1
CLS is an internal command.
Display a message and then immediately clear the screen:
Echo Hello
CLS
Echo You didnt see that
“ For every complex problem there is an answer that is clear, simple, and wrong” ~ H. L. Mencken
ECHO - Display message on screen.
Equivalent PowerShell: Clear-Host - Clear the screen.
