My `.bashrc`

My .bashrc is quite an elaborate setup. I factor most things into files with a .stuff extension. I then put everything in a hierarchy somewhere, such as /usr/jda on my own machines, or $HOME/jda in other places (often I want all users to share the same config on personal machines, since all users are effectively me). The price is that shell startup takes half a second or so, and slightly longer with WSL.

I split the .bashrc into two parts: one sets the paths, even if non-interactive. The other then does everything else once the interactive check has passed.

JDA=/usr/jda
. "$JDA"/etc/bash_paths.bashrc

# If not running interactively, don't do anything
case $- in
    *i*) ;;
      *) return;;
esac

. "$JDA"/etc/bash_common.bashrc

bash_paths.bashrc

The tidypath script removes non-existent directories and duplicate directories from the PATH.

# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples
