That's a very good explanation, ET.
I might add that, Lee, you *never* want to reset the path to nothing. I
expect that would break things severely, as most programs (all except
the ones specified with an absolute path, which are few) would no longer
be able to be found.
The best/safest way to do this is as ET explained. Fiddling with $PATH
is something that rarely needs doing though. I'm wondering, what leads
to be wanting to change your $PATH?

I believe you are asking the wrong question, because you also state (one
of) the right answer(s).
You "edit $PATH" (as you say) by:
PATH=$PATH:/something/else
That only "edits PATH" on your current shell.
($PATH is just a shell variable private to a shell)
There is is not a "global" $PATH...
You "make the change stick", by editing .bashrc, which gets sourced
every time you start a login shell.
So far so good, you answered your own question, now:
and I'll wait till a reboot
There are many "creative" ways to accomplish this, all of them more
complicated than just editing your .bashrc, opening up a new login shell
that will "see" the change (your current shell is unchanged), test the
change, and possible reverse the changes.
A "reboot" is totally unnecessary, once .bashrc is changed, any
subsequent launched process will "see" the change, and conversely, those
already running will be oblivious to it.
You could possibly create a script in .bash_logout that detects a file,
automagically edits .bashrc, bla, bla, bla, sounds to me like one of
those machines like:

Get the drift? :)

Is there a way to edit $PATH ? I am using Ubuntu. I do not want anything
like:
export PATH=...additional paths..:$PATH
in .bashrc, that's just causing me problems.
I simply want to edit the path directly and I'll wait till a reboot to
have it stick. If there's no\ way to do this then how do I reset the
path to nothing and start over? The bashrc this is this additive thing
and just confuses me.
Thanks
