Cheat Sheet

shfmt is a shell parser, formatter and interpretter that supports POSIX Shell, Bash and mksh.

Frequently used flags:

-version
	Show version and exit.

-l
	List files whose formatting differs from shfmt's.

-w
	Write result to file instead of stdout.

-d
	Error with a diff when the formatting differs.

-s
	Simplify the code.

-f
	Recursively find all shell files and print the paths.

Examples
