🐚 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
