What's CreateObject?
All I know is that I've never seen any VBA code with 20-digit GUIDs in
it. And I've never seen it in documentation either. It just pretends
that you're manipulating objects.

It's too dark for mirrors. ;-)

Obviously I'd prefer to spend my time doing something that "almost never
actually works", right? (IOW, the fact that I do in fact do this should
demonstrate to you that it *does* actually work more often than not,
because I'm not likely to waste my time doing something that is unlikely
to work).

That's actually something I do use it for as well - I've been known to
scrape newsgroups with a perl script, dump the contents, and then use
grep to parse the output file to find a message I was looking for based
on something in the message text.

Well, perhaps you would benefit from using it (perhaps not), but just
because you weren't aware of its capabilities, you never considered it as
an option to accomplish a task. It's only natural that one wouldn't use
a tool that might be well suited for a task if one doesn't know about the
tool or fully understand its capabilities.

It looks up names in the registry and translates them to 20-digit GUIDs.
It's like complaining you don't see IP addresses in hyperlinks, so the web
must not use IP.

Yesterday, the 'parted' tool was giving me a totally cryptic error message.
$ apt-get source parted
$ cd parted-2.2
$ grep -rn "error message here" .
-r makes search recursive, -n makes grep output line numbers next to the
filenames. Then I opened a text editor on the file and line number that grep
mentioned, and tried to figure out the code :)

There could be more spaces.
grep '#include[[:space:]]\+"header.hh"' *.cc
How long would it take to write a program that can match that, taking into
account that there could be multiple spaces?

Default UI? There is no option to make it work in a different way. It's not
the default UI, it's the *only* UI.

Something "as simple" is not as simple as it seems. Like, something as
simple as displaying lines of text on the screen could take a few
seconds on early mainframes and PCs...

Which of the lines in this chat log contains a normal message, as opposed to
information like "Jim has joined #povray" or "Logfile started"?
I piped the result of that grep into 'sed' to extract only the username,
then sort | uniq -c | sort -n, and I got an ordered list of who talks the
most in the chatroom :)
