No. The file utility POSIX spec is available here: http://www.opengroup.org/onlinepubs/009695399/utilities/file.html As you see, the -d/h/m/M options are marked UP (part of User Portability extension). Our -i option does something different from POSIX. # I wonder that what jobs these options should perform? See the Open Group's POSIX spec above. # And is there any # developer currently working on it? Not that I know of. Volunteers welcome.
