Hi all,
I'm trying to find out what is the equivalent of file <filename> from
unix in ruby. Basically this command gives the file type - ASCII, BINARY
etc.
Please help!
-Thanks

There is currently nothing written in ruby that uses a library of signatures to attempt to figure out the file type of a file. The best you can do right now is a library that looks at the file suffix and determines what file type matches it.
Download Austin Zeigler's mime-types lib (when Rubyforge is playing nicely again).
mime_type = MIME::Types.type_for(filename)

If your program will always run on a system where that command is
available, you could do:
file_type = `file #{filename}`
That's not *quite* true. I think it's safer to say that there's
nothing currently working in Ruby that does that. However, CRUserS
(the Calgary Ruby Users' Society) is working on a libmagic port to
Ruby as part of an ongoing hacking night. I'm not sure their current
status, and hope that they'll be setting things up to link into
MIME::Types when it's all done, but they are working on it and there
is code in their source repository on RubyForge.

Yes. Filemagic only binds to the existing libmagic, which still
doesn't help much for Windows users.
