🐚 What is ZSH (and Why Use It?)

ZSH (Z Shell) is an advanced Unix shell designed to be a more powerful and user-friendly alternative to Bash.

It provides:

• Smarter tab completion
• Command auto-suggestions
• Better globbing and scripting capabilities
• Plugin ecosystem (via frameworks or standalone plugins)
• Improved developer ergonomics

For power users and engineers, ZSH significantly enhances productivity compared to traditional shells.

⚡ What is Starship?

Starship is a fast, minimal, and highly customizable cross-shell prompt.

Instead of heavy frameworks, Starship delivers:

• Blazing-fast prompt rendering (written in Rust)
• Git-aware status indicators
• Language/runtime detection (Node, Python, etc.)
• Clean and consistent prompt across shells

It integrates seamlessly with ZSH and replaces traditional prompt customization approaches.

🔍 Why This Project Exists

In real-world environments (especially shared systems, lab setups, or enterprise fleets), manually configuring ZSH per user introduces:

• Configuration drift
• Broken environments
• No rollback strategy
• Inconsistent developer experience

This tool solves those problems with a state-driven and reversible approach.

📦 Key Features

• ✅ Per-user installation and rollback
• ✅ Deterministic state tracking
• ✅ Safe .zshrc deployment (non-destructive)
• ✅ Starship prompt integration

• ✅ Plugin management:

  • autosuggestions
  • syntax highlighting

• ✅ Full cleanup mode

• ✅ Centralized logging

---

⚙️ Supported Systems

• Fedora
• RHEL
• AlmaLinux
• Rocky Linux

🚀 Quick Start

1. Download the Script

git clone https://github.com/DipadityaDas/InstallZsh.git
cd InstallZsh
chmod +x zsh_manager.sh

---

2. Install ZSH for a User

sudo ./zsh_manager.sh install <username>

Example:

sudo ./zsh_manager.sh install dipaditya

---

🔧 What the Script Does

Behind the scenes, the script:

• Saves the current shell state
• Installs dependencies:
  • zsh, git, fzf, curl
• Enables Starship via COPR
• Installs plugins:
  • zsh-autosuggestions
  • zsh-syntax-highlighting
• Deploys configs:
  • /etc/starship/starship.toml
  • ~/.zshrc
• Switches the user shell to ZSH

---

🔍 Check Status

sudo ./zsh_manager.sh status <username>

---

🔄 Revert Anytime (Safely)

Standard Revert

sudo ./zsh_manager.sh revert <username>

Full Cleanup Mode

sudo ./zsh_manager.sh revert <username> --full-cleanup

---

📂 File Structure

Path	Purpose
/var/lib/zsh_manager/	State tracking
/var/log/zsh_manager.log	Logs
/etc/starship/starship.toml	Global config
~/.zshrc	User config

---

🛡️ Safety First

• State-based rollback (no guesswork)
• Existing .zshrc is preserved
• System users are skipped
• Designed for idempotent execution

---

🧪 Example Workflow

sudo ./zsh_manager.sh install dipaditya
sudo ./zsh_manager.sh status dipaditya
sudo ./zsh_manager.sh revert dipaditya
sudo ./zsh_manager.sh revert dipaditya --full-cleanup

---

💡 Future Enhancements

• Dry-run mode (--dry-run)
• Bulk user operations (--all-users)
• RPM packaging
• Ansible role integration
• Version flag support
