'file's manpage says about it's history:
There has been a file command in every UNIX since at least Research Version 4 (man page dated November, 1973). The System V version introduced one significant major change: the external list of magic types. This slowed the program down slightly but made it a lot more flexible.
This program, based on the System V version, was written by Ian Darwin without looking at anybody else's source code.
John Gilmore revised the code extensively, making it better than the first version. Geoff Collyer found several inade-quacies and provided some magic file entries. Contributions by the `&' operator by Rob McMahon, [email protected], 1989.
Guy Harris, [email protected], made many changes from 1993 to the present.
Primary development and maintenance from 1990 to the present by Christos Zoulas ([email protected]).
Altered by Chris Lowth, [email protected], 2000: Handle the -i option to output mime type strings, using an alternative magic file and internal logic.
Altered by Eric Fischer ([email protected]), July, 2000, to identify character codes and attempt to identify the languages of non-ASCII files.
Altered by Reuben Thomas ([email protected]), 2007 to 2008, to improve MIME support and merge MIME and non-MIME magic, supportdirectories as well as files of magic, apply many bug fixes and improve the build system.
The list of contributors to the `magic' directory (magic files) is too long to include here. You know who you are; thank you. Many contributors are listed in the source files.

如果你用记事本打开脚本，它包含像“ELF”、“ibstdc++”这样的原始字符串，所以我猜它是C++。
If you open the script with notepad, it contains raw strings like "ELF", "ibstdc++", so I guess its C++.
