In fact, Eric Pement has a whole bunch of useful sed information
and links to other references that you can access by using that
URL up to the final "/", not to mention other useful stuff on
awk and (to a lesser extent) perl if you stop at the 2nd last
"/".  You'll also trip over his christian ideology there[1], but
it does not get in the way of the technical information.

However, the URL above does demonstrate yet another annoying bug
in Opera-6.1 which renders the information useless to people who
might need to read it -- Opera displays the "backtick" (`) [0]
character the same as the "single quote" (') character; since
plenty of the examples use both of these characters (and they
are not interchangeable), the examples are tricky to read.

Mozilla-0.9.3 has the same fault as Opera.  Netscape-4.76 and
Konqueror from KDE-3.1 do not have the bug.  Not surprisingly,
w3m does the right thing too.  And, in late-breaking news, I see
that Mozilla-1.3.1 on my Debian box also displays it correctly.

At any rate, it's clear that you need to use the right browser
if you want to get value from this material -- and from lots of
other technical material that is available out there.

Cheers, Greg

[0] If the "`" and "'" look the same to you in your mail reader,
    you also need a new mail reader.

[1] I would not normally make a note of somebody's religious
    beliefs and have no quarrel with any religion; but I find
    that people who make a point of their religion often manage
    to spoil their technical efforts and I wanted to reassure
    potential visitors to Eric's stuff that they could go there
    without having to deal with religion.
