Summary: Use this one-line Windows PowerShell command to display a blinking message.
Is there a one-line command that I could use to blink a message in the Windows PowerShell console to get the users attention?
Pipe a range of numbers to the Foreach-Object cmdlet (% is an alias), clear the screen in the Begin block,
and then display the message, pause, clear the screen, and pause in the Process block:
1..3 | % -begin {cls} -process {"hello";sleep 1;cls;sleep 1}
