Why, thank you !

How lovely. See, I knew there was someone here who could say it better.
I said it first, though :-) I'm just happy I came up with the right
split grammar; it took me three tries!

Well, yeah, probably, but we still haven't covered where he's getting the
PATH and what he's doing with it... If it's, say, a single pass through
to look for a particular directory (but why separate instead of just m//
I wonder in that case, so ...) instead of something where he'll need to
store the path dirs for later, then it seems quite valid to spit through
the elements and iterate them without storing them in an array in the
meantime.
Doesn't it?

No? But why?! :-)

Yes, I have; it comes from too little time to really straighten things
out.
% element - and should seriously think about resolving whether

But if you can set it once and have it work everywhere then it must be
great! :-)
%

%
% setenv ARCH `perl -MConfig -e 'print $Config{osname}'`
Hmmm... Hadn't noticed that one before. Still, firing up perl every
time I start a shell might be a little painful.

Ahhh! If/elseif trees! Ick!

Heh... I'll show you backbone, just as soon as I get around to it...
I'm going to need a ~/local tree that is populated for Linux 2.2 and 2.4,
FreeBSD 4.5, Solaris 1.x, 2,x, and 8, and perhaps cygwin, with at least
Linux and Solaris on multiple chip architectures. Thanks to my handy
dandy $MYOS $MYMAJ $MYMIN $MYCHIP, though, it will all work out nicely.
Once I get it done. Yeah, really.

Heh. On the one hand, nobody takes my env files because they're too
scary. On the other hand, they (the real ones, not this out-of-date play
copy that has been neglected) are ready to drop in place to provide a
system-wide group-aware environment for users which provides everything
the business deems necessary but still allows the user freedom to screw
it up (er, customize it). *That* part I have pretty much down; it's
almost a shrink-wrapped product.
%
% { ok, so like as if my .login and .cshrc files have not bloated
% over the mumble, mumble, mumble years..... }
Same here! That's another project; when I write a perl script (or some
other parser) to go through and take the aliases that I want and spit
them out both in tcsh and bash format, I'll probably do some pruning,
too. All in my copious free time between midnight and three AM...
