2016-02-15Cleanup pass on file.c, and add detection of different ELF architectures.Rob Landley
2016-02-14Implement file(1).Elliott Hughes
Unlike the POSIX file(1), there's no magic file here, just hard-coded common (non-obsolete) file formats. Personally most of my use of file(1) is as a one-line readelf(1) summarizer, so although I assume a full POSIX file(1) is out of scope (because just the database would likely be larger than all the rest of toybox), a subset that only supports in-use file types actually covers most of the use cases I encounter personally. Also fix peek_be/peek_le.
