Shell Script Formatter

Shell Script Formatter processes input entirely in the browser and returns a copy-ready result with diagnostic counts. It is intended for focused checks and small formatting tasks where installing a full toolchain would be unnecessary. The output panel separates the transformed text from review notes so you can spot assumptions before using the result in a repository.

How to use this developer tool

  1. Paste input or load the included sample.
  2. Keep the documented input layout.
  3. Run the tool or press Ctrl/Cmd + Enter.
  4. Review the output and diagnostics.
  5. Copy or download the result.

What this developer tool does

The Shell Script Formatter applies deterministic browser-side rules and reports the amount of input processed.

Leading indentation is rebuilt from recognized block openers and closers while preserving source line order.

Use the result as a review aid and run the project’s canonical formatter, runtime, or test suite before committing.

Example

Input

if [ -f "$FILE" ]; then
echo "found"
else
echo "missing"
fi

Run the sample to see the exact output produced by the current implementation.

Use cases

  • Pre-commit review of a small source fragment
  • Debugging a pattern against representative cases
  • Creating a copy-ready result without a build step
  • Explaining a rule during code review

Tips for reliable output

  • Test edge cases, not only successful examples.
  • Keep a copy of the original input.
  • Use representative production strings.
  • Review escaping after copying output.
  • Run your repository checks afterward.

Processing details

All processing occurs in JavaScript in the current browser tab. The page records counts and elapsed time but does not execute downloaded code.

This is a lightweight structural formatter, not a full language parser. Heredocs, embedded languages, multiline strings, and dialect-specific constructs can require manual adjustment.

Frequently asked questions

Can Shell Script Formatter process large files?

Processing happens in the browser. Very large input may still be limited by available memory and browser execution time.

Does Shell Script Formatter send source code to a server?

No. The page operates locally in the browser and does not require an API request.

What syntax does Shell Script Formatter support?

It implements the documented browser-side rules shown on this page. Dialect-specific extensions may need manual review.

Why should I review the generated output?

Static analysis and lightweight formatting cannot reproduce every parser, runtime, or engine behavior.

Can I use the downloaded result in a project?

Yes. Download the plain-text output, then run the project’s normal linter, test suite, or validator before committing it.
