ec, I realize that control, alt, and delete are NOT commands. I didn't know that crtlaltdel was not a command. My real goal was to break down each element of this command string and understand it. ca::ctrlaltdel:/sbin/shutdown -t5 -h -a now I fully understand the shutdown command but do not understand the ca::ctrlaltdel: portion and could not find documentation on it. I can only assume out of my ignorance that ca captures keyboard strokes and :: if equal to ctrlaltdel executes what follows the :. If that is so what number represents ctrlaltdel and how is it derived? Can the the raw (HEX code)number be substituted for ctrlaltdel? Inquiring minds would like to know.
