Bash

Bourne Again SHell, the standard shell for Linux and macOS.

When to Use

  • Automating system tasks
  • CI/CD pipelines
  • File manipulation
  • Glue code between CLIs

Quick Start

#!/bin/bash

NAME="World"
echo "Hello, $NAME!"

if [ -f "file.txt" ]; then
    echo "File exists"
else
    echo "File not found"
fi

Core Concepts

Variables

No data types. Everything is a string.

count=10
echo $count

Pipes and Redirection

  • |: Pipe output of one command to input of next.
  • >: Redirect output to file (overwrite).
  • >>: Redirect output to file (append).
cat file.txt | grep "error" > errors.log

Exit Codes

Commands return 0 for success and non-zero for failure. Check with $?.

Best Practices

Do:

  • Use set -e (e)xit on error
  • Use set -u (u)nset variable usage is error
  • Use set -o pipefail to catch errors in pipes
  • Quote variables "$VAR" to handle spaces

Don't:

  • Parse ls output (use globs *)
  • Use simple [ vs [[ (double brackets are safer)
