Bash / Shell

What is Bash / Shell, really?

Bash is the command line language for Linux and Mac. It is what runs on servers when you SSH in, what most automation scripts are written in, and what every DevOps role requires. The basics take a weekend. Becoming truly fluent takes years and saves entire days every month.

Why learn it in 2026?

Bash skills directly translate to DevOps and SRE salaries (often ₹15+ LPA in India). Even as a regular developer, automating routine tasks with Bash will easily save you 5 hours a week. That is 250 hours a year.

What it looks like

#!/bin/bash
# Backup all .sql files older than 7 days
find /backups -name "*.sql" -mtime +7 \
    -exec gzip {} \;
