Is it reading my zsh initialization files to get that information, or or getting that information from some other source? Environment variables are passed from parent processes to their children. That's why they are called "environment" variables. A shell also has variables that exist for its own use in command lines that are NOT part of the environment. You can see all shell variables using the 'set' command and all environment variables with the 'env' command. You can turn a normal variable into an environment variables with 'export VARIABLENAME' and POSIX-compliant shells can also be configured to export all variables automatically. TL;DR: you'll need shell init files for fish. -- Bill Cole b...@scconsult.com or billc...@apache.org (AKA @grumpybozo and many *@billmail.scconsult.com addresses) Not Currently Available For Hire
Question about fish shell initialization settings...
I installed the fish shell from mp a few days ago, and I’ve been loving it so far, but I’ve been wondering about where certain environment variables get set on startup… On starting the shell, (within zsh at the moment, because fish isn’t yet my default shell, since I am only just now learning it), it already seems to know all of the environment variables eg: $PATH, $CPATH, $CLASSPATH, etc, that I set from within the zsh initialization files. Is it reading my zsh initialization files to get that information, or or getting that information from some other source? When I finally switch to fish as a default shell do I need to write those environment variables into a fish config file for fish to find it, or will it somehow find it on its own? I’ve read the fish documentation, and it isn’t totally clear on this point.
