Well, i find "head" and "tail" very useful. For example, the process id
number of sendmail is stored in /var/run/sendmail.pid, as is a bunch of other
info; i can restart sendmail with "kill -HUP `head -n 1 /var/run/sendmail.pid`".
Similar tricks with /proc info are no doubt applicable. Head and tail can be
useful for stripping excess data from records;

Yes, we ARE a bunch of anal, short-tempered, quick to fly-off-the-handle,
sarcastic, know-it-alls. That's what running networks does to you.
