Bash Formatter
Format and beautify Bash/Shell scripts with proper indentation and structure
Bash Formatting Tips
- Use consistent 2-space indentation for better readability of nested blocks.
- Always quote variables with double quotes to prevent word splitting and globbing.
- Add shebang lines (#!/bin/bash) at the top of your scripts for portability.

Frequently Asked Questions
Common questions about Bash Formatter formatting answered
Yes, our Bash formatter is completely free with no registration required. All processing happens in your browser.
Yes, our formatter supports Bash, SH, and ZSH syntax constructs including conditionals, loops, functions, and case statements.
No. The formatter only adjusts whitespace and indentation. It never modifies commands, variables, or logic, so your script behavior remains identical.
Yes, the formatter handles heredocs, subshells $(...), backticks, and complex nested structures properly.
By default, it uses 2-space indentation which is the most common convention for shell scripts. You can adjust the indentation size.
Google's Shell Style Guide (the most-cited bash standard): 2-space indent, function names snake_case, function keyword omitted (my_func() { form), and [[ ]] preferred over [ ] for tests. shellcheck - the static analyzer every CI runs - defaults to recommending the same conventions.
Quoting is never "fixed": "$var" vs $var differ in word-splitting and globbing semantics, so the formatter leaves each exactly as written and only reports the risky unquoted expansions (the same cases shellcheck SC2086 flags). Adding quotes automatically would change behavior in the rare cases where splitting is intended.
Heredoc bodies (cat <<EOF ... EOF) are left verbatim - they are the payload, not script. case patterns indent one level with ;; on their own line, matching Google style. Backslash continuations keep their trailing backslash exactly at end-of-line; reflowing them would risk joining lines the shell treats as separate commands.
