#+title: General Shell Configuration #+setupfile: headers #+PROPERTY: header-args:sh :mkdirp yes :tangle ~/.profile :exports code :noweb yes :shebang #!/bin/sh #+PROPERTY: header-args :exports code :tangle no * General Shell Configuration As you may have noticed with my [[file:./fish.md][Fish configuration]], my main shell is Fish, not Bash or Zsh. But sometimes, I do need to use these instead of Fish. In order to share some common configuration, I have a rather rich =$HOME/.profile= file which mainly exports environment variables. Despite the fact Fish is not a POSIX shell and should not be able to read it, the plugin =foreign-env= comes in handy to load this =.profile= from fish, as you can see [[file:./fish.md#global-variables][in my fish config]]. The correctness and POSIX compatibility of this file is verified using [[https://www.shellcheck.net/][shellcheck]]. Before we go into the meaty stuff, let me first load some private configuration I cannot share online. #+begin_src sh # shellcheck source=/dev/null .
