fdncred/nu_plugin_file

A nushell plugin that will inspect a file and return information based on it's magic number.

nu_plugin_file

This nushell plugin will open files to inspect them and report back a little information. It uses magic bytes to determine many file formats. The core code was "borrowed" from a spacedrive crate that I thought looked interesting.

Usage:

❯ help file
View file format information

Usage:
  > file <filename>

Flags:
  -h, --help - Display the help message for this command

Parameters:
  filename <string>: full path to file name to inspect

Examples:
  Get format information from file
  > file some.jpg
