BASH Snippets.

Parse JSON with jq for API Response Extraction

Efficiently extract specific values from JSON data returned by API calls using the powerful 'jq' command-line JSON processor in Bash scripts.

Execute Remote Commands via SSH in Bash

Automate tasks on remote servers by securely executing commands over SSH directly from your Bash scripts, perfect for web server management and deployment.

Implement Robust Script Cleanup with Trap

Ensure Bash scripts clean up temporary files or stop background processes automatically upon exit or interruption using the 'trap' command for reliability.

Automate Website Deployment with Rsync

Streamline web deployments by synchronizing local changes to a remote server efficiently using rsync, ensuring only modified files are transferred, saving time and bandwidth.

Monitor and Restart a Web Service

Create a bash script to periodically check if a critical web service (e.g., Nginx, Apache) is running and automatically restart it if it's down, ensuring continuous uptime.

Filter and Analyze Web Server Access Logs

Quickly filter and analyze web server access logs (e.g., Apache, Nginx) for specific patterns like error codes, IPs, or URLs using `grep`, `awk`, and `sort` for rapid debugging.

Create Timestamped Directory Backups

Generate compressed, timestamped backups of important directories like website content or configurations using `tar`, ensuring easy restoration and versioning control.

Managing Concurrent Background Services for Local Development

Efficiently start and manage multiple development services (e.g., frontend, backend, database) in parallel within a single terminal session using Bash.

Automated Website Deployment with Rsync

Synchronize local website files to a remote server securely and efficiently using Rsync over SSH for streamlined automated deployments.

Automating Git Repository Setup and Updates

Streamline development workflows by automating Git cloning, pulling, and dependency installation for new or existing projects.

Monitoring and Cleaning Up Disk Space on Servers

A practical Bash script to check disk usage, identify large files or directories, and automate cleanup of old log files on a server.

Dynamically Updating Configuration File Values

Automate the modification of specific key-value pairs within configuration files (like `.env`) using Bash and `sed` for environment-specific settings.
