| Readme: | Short: Determine file MIME type from its contents
Author: Ian Darwin, Christos Zoulas et al

Type: util/misc
Version: 5.48
Architecture: m68k-amigaos >= 2.0; ppc-amigaos; ppc-morphos
Amiga port of the "file" UNIX app. It identifies the type of a file by
inspecting its contents rather than trusting its name or filenote. It
recognises several thousand formats, from Amiga hunk executables and IFF
containers through to modern archive, image, audio and document types.
This is a port of the standard Unix file(1), version 5.48. Native binaries
are included for AmigaOS 3 (68k), AmigaOS 4 (PPC) and MorphOS (PPC).
Installation
Copy the contents of the C/ directory for your system to C:, e.g. on
AmigaOS 3:
copy file/AmigaOS3/C/#? C:
Both the "file" command and its magic database "magic.mgc" belong in C:.
The command looks for the database next to itself, so keeping them
together is all that is required.
Usage
file <name> identify one or more files
file -i <name> print a MIME type instead of a description
file -b <name> omit the filename from the output
file --help full option list
Examples:
1> file C:file
C:file: AmigaOS loadseg()ble executable/binary
1> file -i Work:Pictures/photo.jpg
Work:Pictures/photo.jpg: image/jpeg
Notes
Compressed-file inspection using external decompressors is not available:
AmigaOS provides no sigaction(), and clib2 no pipe(), so that code path is
compiled out. Reading compressed files directly is unaffected.
The developer SDK (static libmagic.a libraries and magic.h) is distributed
separately as magic.lha.
Licence
BSD-style; see COPYING in the source distribution.
