The same commands work but the hard part is knowing where to display before
someone logs in. Is this a text console or do you have a graphic login box showing?
And by the way, you don't need a pipeline of 4 commands to grab a bit of text.
Sed can do everything that grep does and more, awk can do anything sed can do.
If you use one of the more powerful commands you might as well let it do all the
work instead of building a pipeline.
