Modular Bashrc Manager

A simple, modular, and clean way to manage your .bashrc file in Linux.

---

Modular Bashrc Manager is a shell-based system designed to keep your Bash configuration clean, structured, and easy to maintain.
Instead of placing everything directly inside .bashrc, this project lets you split your configuration into modular scripts that are loaded automatically at shell startup.

The project includes:

• an automated intelligent installer with OS detection and automatic migration
• a command-line management tool (brc-script)
• a modular directory layout (scripts-available, scripts-enabled, scripts-needed, scripts-removed)
• default ready-to-use scripts (Git highlights, multi-distro bashboard with Cockpit auto-detection, aliases)
• a reusable colored echo utility (ccecho)
• Gitea update and self-upgrade mechanism

This makes it easier to add, remove, enable, disable, preview, and maintain shell customizations without turning .bashrc into a long and messy file.

Features

• Modular setup
  Keep .bashrc organized by loading only the scripts you need.

• Intelligent Installer & Migration
  Automatically migrates your pre-existing .bashrc into 00_default.sh and enables it, cleans .bashrc to only contain the loader, and installs required tools (jq, curl) matching your Linux distribution.

• Multi-Script Management
  Enable or disable multiple scripts in a single command using numerical IDs or script names (e.g. brc-script -d 1 5 12 10 or brc-script -e 01_git-cli-highlitgh 03_bashboard).

• Quick Script Preview (cat)
  Inspect script content and line numbers directly from the terminal with brc-script -p <id|name> without opening text editors.

• Cockpit Auto-Detection
  03_bashboard.sh automatically detects if Cockpit is installed and running, discovers its listening port dynamically (from /etc/cockpit/cockpit.conf, systemd sockets, or 9090), and shows the direct URL.

• Gitea Updates & Upgrades
  Check for project updates directly from Gitea with brc-script --update and upgrade core and standard scripts safely with brc-script --upgrade without touching your personal customizations.

• Reusable utility functions
  Includes ccecho, a colored echo helper for cleaner terminal output.

How It Works

The installer backs up your existing .bashrc, migrates its content into ~/.bashrc.d/scripts-available/00_default.sh, enables it, and replaces .bashrc with a minimal loader block.

That block sources scripts from the modular directories:

• scripts-needed/
  Essential logic scripts required for the system to work (brc-script.sh, ccecho.sh).
• scripts-enabled/
  Scripts that should be loaded at shell startup (symlinks to scripts-available/).
• scripts-available/
  Scripts that are installed and ready to be enabled or customized.
• scripts-removed/
  Scripts that were removed and stored as timestamped backups.

---

Directory Structure

After installation, the system uses the following layout:

~/.bashrc.d/
├── .version
├── scripts-needed/
│   ├── brc-script.sh
│   └── ccecho.sh
├── scripts-available/
│   ├── 00_default.sh
│   ├── 01_git-cli-highlitgh.sh
│   ├── 02_git-cli-highlitgh-root.sh
│   ├── 03_bashboard.sh
│   └── 04_aliases.sh
├── scripts-enabled/
│   └── 00_default.sh -> ~/.bashrc.d/scripts-available/00_default.sh
└── scripts-removed/

Installation

Automated Installation

1. Clone the repository from the official Gitea server:

git clone https://gitea.sld-server.org/sld-admin/Modular-Bashrc-Manager
cd Modular-Bashrc-Manager/installer

2. Make the installer executable and run it:

chmod +x brc-script-install.sh
./brc-script-install.sh

What the installer does:

• Detects the Linux distribution (apt, dnf, yum, pacman, zypper, apk, brew) and automatically installs jq and curl if missing.
• Creates timestamped backup of your current .bashrc.
• Automatically copies your existing .bashrc content into ~/.bashrc.d/scripts-available/00_default.sh and enables it.
• Writes the clean modular loader block to .bashrc.
• Copies core scripts to scripts-needed/ and default scripts to scripts-available/.
• Initializes the .version file for future update tracking.

3. Reload .bashrc:

source ~/.bashrc
# or run: refresh-brc

Usage (brc-script)

The main command-line management tool is brc-script.
