Bash Scripting Basic Hygiene Checklist


Task
Recommendation
Why?


The Shebang
#!/usr/bin/env bash
Maximum portability across different Unix-like systems.

Error Handling
set -euo pipefail
Ensures the script stops at the first sign of trouble.

Quoting
"$VARIABLE"
Prevents word splitting and globbing (essential for paths).

Variable Style
local_var="value"
Lowercase prevents overwriting system-wide environment variables.

Boilerplate
readonly CONSTANT
Prevents accidental modification of fixed values.

Extensions
.sh or none
Helps with syntax highlighting and identifying file types.
