If you _are_ going to make a script, all sorts of options are available.
As I said before, the problem is that it will have to be made easy to
install... packaged, I guess. Not insurmountable, but I still like
instructions that encourage people to examine their own diagnostics.

echo doesn't process escapes unless told to.

The idea of using tests to distinguish which set of diagnostic
utilities to use is slick.
I did notice that this fails to inform the reader which commands were in
fact executed, and sequence can't really be relied on unless everyone
agrees what it should be.

I prefer to be able to specify output destination. This may be
undesirable from the point of view of teaching the uninitiated how to use
it, but I think the trade is worth it.

Of course, you are stuck if your system doesn't have "which" :)

But functions can reduce this a bit.
Disclaimers:
My modifications have been tested on a frankenstein 2.2.19 LRP 2.9.8.
I have not really reviewed the set of diagnostics for completeness yet.
For example, lsmod probably ought to be included. Perhaps "cat
/etc/issue" ought to be included as well.
Diagnostics from multiple participating machines are often needed to
troubleshoot actual networking problems, and the choices encoded in a
script like this one may have to be manually applied by the user to other
operating systems before a meaningful solution can be found.
