ABC Bash

My personal bash and readline setup for Linux, WSL and Git Bash on Windows, plus an optional WezTerm config.

---

What's included

Repo file	Installed as	What it does
.bashrc	~/.bashrc	History, a git-aware prompt, aliases and small cd helpers
.bash_profile	~/.bash_profile	Login shells: sources ~/.profile, then ~/.bashrc
.profile	~/.profile	Adds ~/usr/bin and ~/usr/lib to PATH and the library search paths
inputrc	~/.inputrc	Readline: no bell, case-insensitive completion, arrow-key history search
.wezterm.lua	~/.wezterm.lua	Optional WezTerm config (Windows and Linux); opens Git Bash on Windows

---

Install

git clone https://github.com/aaronbcarlisle/abc-bash.git ~/abc-bash
sh ~/abc-bash/install.sh

The installer copies the files above into your home directory. It's safe to re-run:

• A file that doesn't exist yet is installed.
• A file that already matches the repo is skipped.
• A file that differs from the repo is left alone, and the installer tells you which ones it skipped.

Open a new terminal (or source ~/.bashrc) afterwards.

Options

Option	Effect
--force	Replace files that differ from the repo. Each one is first moved to <file>.bak.<yyyyMMddHHmmss>, so nothing is lost.
--wezterm	Also install .wezterm.lua.
--help	Show usage.

For example, to take over an existing setup and keep backups of the old files:

sh ~/abc-bash/install.sh --force

The installer lists every backup it made. Compare them with the new files (diff ~/.bashrc.bak.<stamp> ~/.bashrc) and delete them when you're done.

Updating

git -C ~/abc-bash pull --ff-only
sh ~/abc-bash/install.sh --force

--force is needed here because the installed files are copies: once the repo changes, they differ from it. Without it, the installer only reports which files are out of date.

Notes

• Windows: run the installer from Git Bash. The WezTerm config starts Git Bash as a login shell, so ~/.bash_profile and ~/.bashrc both load.
• Machine-specific changes: put them in ~/.bashrc.local, which .bashrc sources last and the installer never touches. The installer also won't overwrite a file that differs unless you pass --force.
