Shell parser, formatter and interpreter. More information: <https://pkg.go.dev/mvdan.cc/sh>.

• 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
