Recently there was a change at work -- all http access now needs to
go through a proxy.
So if I have a script using LWP::UserAgent or similar, I have to add
$UA->proxy( ['http'] , 'http://proxy.fake.com:8080' );
to all my scripts. Which is a big pain. So a *NIX guy said "you
shouldn't need to do that if you can add an environment variable to
your shell".
So, as I use tcsh, not bash, which is the default nowadays, I added
this to .tcshrc:
setenv http_proxy http://proxy.fake.com:8080
and it seemed to work, but leaving aside the specifics of the
scripts, how would Perl "know" that I use tcsh, not bash? Isn't that
a preference of the Terminal app, not of me as a user? A script run
as a cron job, does it run using all the environment variables as if
I'd typed its name into the Terminal? What about a script run from
BBEdit? What if I "su root" and run it?
I'd really appreciate someone explaining the relationship of script
to shell and user.
