Oh, my.  chown was definitely an oversight.  That
should have been in there.

My opinions:
  * head, tail, and tee are no-brainers; just do it.
  * sed would be a nice addition.  (I atttempted to
fit 'vi' in there, but curses is rather finicky;
'sed' would be more useful.)
  * I personally would not add pgrep/pkill because I
never use them.

Of course, it's hard to get worked up about 45k,
so feel free to ignore the above.
