Automate Updating Multiple Git Repositories

A Bash script to efficiently navigate through multiple Git repositories within a parent directory and pull the latest changes, streamlining your development workflow.

Automatically Remove Old Files and Directories

Use a Bash script to automatically find and delete files or empty directories older than a specified duration, ideal for routine cleanup of logs, cache, or temporary data.

Extract Key-Value Pairs from Configuration Files

A powerful Bash snippet to parse and extract specific configuration values (e.g., database host, API keys) from text-based configuration files using grep and awk.

Create a robust Bash script to periodically check the status of a web service (e.g., Nginx, Apache) and automatically restart it if it's not running.

Automate Project Dependency Installation

Streamline project setup by automatically detecting and installing Node.js, Python, or Ruby dependencies based on common lock files, saving development time.

Find and Kill Process Running on a Specific Port

Quickly identify and terminate any process occupying a specified TCP port, essential for resolving port conflicts during web development server startups.

Monitor File Changes and Trigger a Command

Create a simple file watcher using `inotifywait` that automatically executes a specified command, like a build script or server restart, when files in a directory change.

Batch Rename Multiple Files Using Regular Expressions

Efficiently rename a collection of files in a directory by applying a regular expression search and replace pattern, ideal for organizing assets or refactoring filenames.

Add or Remove Local Host Entries for Development

Easily manage entries in your `/etc/hosts` file, allowing you to map custom domain names (e.g., `myapp.local`) to `127.0.0.1` for local web development.
