shebang-command

What is shebang-command?

The shebang-command npm package is used to parse the shebang (#!) line of a file to determine which interpreter should be used to execute the file. This is particularly useful when working with scripts in a Node.js environment where you might need to identify the interpreter specified in a script file.

What are shebang-command's main functionalities?

This feature allows you to extract the command from the shebang line of a script. The code sample represents a script file with a shebang line that specifies that the script should be run with Node.js.
