Grepping in a '^(Unix|Wonderland)$'

Let us ping, is it listening?
When you fing @snow.glistening
An ftp site, mgetting tonight,
Grepping in a '^(Unix|Wonderland)$'

Gone away: /usr/bin/sh,
Here to stay is tcsh
I'm in .deny (cron), my .newsrc's gone
Grepping in a '^(Unix|Wonderland)$'

In the rootdir we can build a shellscript
And pretend that it is parsing 'brown'
It echos 'Are you @ing?' We'll say "No man."
But use expr when you're in town

Later we'll use vi
As we find for some files
To face and forsake xmkmf when we make
Grepping in a '^(Unix|Wonderland)$'
