This procedure is tested on Linux Mint 20. It should also work on any recent Ubuntu or other Debian based distribution.

See Shared below for a version that does not modify any existing files.

$ curl github.com:rogerdahl/bashrc/install | bash

The installation uses git clone to create a copy of this repository in ~/bin/bashrc.d, creating the directories as needed.

It then moves the original ~/.bashrc to ~/bin/bashrc.d/_bashrc.original and replaces it with a call to ~/bin/bashrc.d/bashrc.

You should then move any custom goodies from your ~/.bashrc (now at ~/bin/bashrc.d/_bashrc.original) into DD-name.sh files (where DD is a two-digit number). DD range from 90 to 99 has been left open for this purpose.

• This is the same as Full, except that it does not modify ~/.bashrc (or any other login scripts), and so does not alias any existing commands or otherwise change the look, feel or behavior of the account.

• After logging in, activate bashrc.d with . ~/bin/bashrc.d/bashrc. This can be added as a quick alias by adding alias rcd='. ~/bin/bashrc.d/bashrc' to the end of ~/.bashrc.d.

• bash has a cheat sheet! Just type help at the bash prompt.

• bashrc.d is only active in interactive shell sessions. However, it adds and modifies exported environment variables, so it may influence the behavior of programs and scripts started from the interactive shell.

• When writing new scripts that are intended to work outside of a bashrc.d environment, make sure you don't introduce any dependencies on the bashrc.d environment.

• When an interactive bash shell is opened, the shell scripts on form <digit><digit>-<name>.sh are sourced in ascending numerical order. All other scripts and files are only used if they are referenced by one of the numbered scripts.

  All the numbered scripts are sourced in the same environment, so the results from scripts that have been sourced become available to the scripts yet to be sourced. So each script can depend on all scripts with lower numbers, but must not depend on any scripts with the same or higher numbers.

  When the process is completed, the interactive environment represents the final result.

• In addition to describing the order in which the scripts are sourced, the leading two digits also describe categories, as follows:

• 00 - 09 - Reserved for local use
• 10 - 19 - Basic settings and utilities useful in both interactive shell and scripts
• 30 - 39 - Set up development and build environments
• 60 - 69 - Shortcuts and convenience commands for working in the shell
• 80 - 89 - GUI related scripting / automation
• 90 - 99 - Reserved for local use

Features of the interactive environment set up by .bashrc.d.
