bashrc.d.md

Example ~/.bashrc.d/ folder found at:

github.com/bcomnes/dotfiles/tree/master/home/bashrc.d

Load order can be further enforced with init.d style number prefixes:

00_rc_snippet.sh # runs before...
01_rc_snippet.sh # ...
20_rc_snippet.sh # etc

You can also call this same pattern for subfolders e.g. .bashrc.d/darwin, .bashrc.d/linux etc.

#!/bin/bash

# `.bashrc.d/platformrc.sh`
