Clears the display in the host program.
Clear-Host [<CommonParameters>]
The Clear-Host function removes all text from the current display, including commands and output that might have accumulated. When complete, it displays the command p
rompt. You can use the function name or its alias, CLS.
Clear-Host affects only the current display. It does not delete saved results or remove any items from the session. Session-specific items, such as variables and func
tions, are not affected by this function.
Because the behavior of the Clear-Host function is determined by the host program, Clear-Host might work differently in different host programs.
