shebang-command
Advanced tools
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.
Parse shebang line
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.
"#!/usr/bin/env node\nconsole.log('Hello, world!');"The shebang-regex package provides a regular expression for matching shebang lines. It is similar to shebang-command in that it helps with shebang lines, but it does not parse the line to extract the command; it only provides the regex for matching.
The hashbang package is another tool that can be used to manage shebang lines in scripts. It is similar to shebang-command but offers a different API and might have different use cases or preferences for developers.
