shfmt

Shell parser, formatter and interpreter.

Print a formatted version of a shell script

$ shfmt [path/to/file]

List unformatted files

$ shfmt --list [path/to/directory]

Write the result to the file instead of printing it to the terminal

$ shfmt --write [path/to/file]

Simplify the code, removing redundant pieces of syntax (i.e. removing "$" from vars in expressions)

$ shfmt --simplify [path/to/file]
