Default What does your .*shrc file look like?

What does your shells initialization file look like?

On my systems, the individual shells own profile/shrc's just source this through . or ENV.

site_shrc defines things specific to the current machine, I find it useful for adjusting the environment variables:

I've used FreeBSD since November 2005.
