** README for file(1) Command ** @(#) $Id: README,v 1.24 2001/03/12 05:05:57 christos Exp $ This is Release 3.x of Ian Darwin's (copyright but distributable) file(1) command. This version is the standard "file" command for Linux, *BSD, and other systems. (See "patchlevel.h" for the exact release number). UNIX is a trademark of UNIX System Laboratories. The prime contributor to Release 3.8 was Guy Harris, who put in megachanges including byte-order independance. The prime contributor to Release 3.0 was Christos Zoulas, who put in hundreds of lines of source code changes, including his own ANSIfication of the code (I liked my own ANSIfication better, but his (__P()) is the "Berkeley standard" way of doing it, and I wanted UCB to include the code...), his HP-like "indirection" (a feature of the HP file command, I think), and his mods that finally got the uncompress (-z) mode finished and working. This release has compiled in numerous environments; see PORTING for a list and problems. This fine freeware file(1) follows the USG (System V) model of the file command, rather than the Research (V7) version or the V7-derived 4.[23] Berkeley one. That is, the file /etc/magic contains much of the ritual information that is the source of this program's power. My version knows a little more magic (including tar archives) than System V; the /etc/magic parsing seems to be compatible with the (poorly documented) System V /etc/magic format (with one exception; see the man page). In addition, the /etc/magic file is built from a subdirectory for easier(?) maintenance. I will act as a clearinghouse for magic numbers assigned to all sorts of data files that are in reasonable circulation. Send your magic numbers, in magic(4) format please, to the maintainer, Christos Zoulas. LEGAL.NOTICE - read this first. README - read this second (you are currently reading this file). PORTING - read this only if the program won't compile. Makefile - read this next, adapt it as needed (particularly the location of the old existing file command and the man page layouts), type "make" to compile, "make try" to try it out against your old version. Expect some diffs, particularly since your original file(1) may not grok the imbedded-space ("\ ") in the current magic file, or may even not use the magic file. apprentice.c - parses /etc/magic to learn magic ascmagic.c - third & last set of tests, based on hardwired assumptions. core - not included in distribution due to mailer limitations. debug.c - includes -c printout routine file.1 - man page for the command magic.4 - man page for the magic file, courtesy Guy Harris. Install as magic.4 on USG and magic.5 on V7 or Berkeley; cf Makefile. file.c - main program file.h - header file fsmagic.c - first set of tests the program runs, based on filesystem info is_tar.c, tar.h - knows about tarchives (courtesy John Gilmore). magdir - directory of /etc/magic pieces magdir/Makefile - ADJUST THIS FOR YOUR CONFIGURATION names.h - header file for ascmagic.c softmagic.c - 2nd set of tests, based on /etc/magic readelf.[ch] - Standalone elf parsing code. compress.c - on-the-fly decompression. internat.c - recognize international `text' files. print.c - print results, errors, warnings. If your gzip sometimes fails to decompress things complaining about a short file, apply this patch [which is going to be in the next version of gzip]: *** - Tue Oct 29 02:06:35 1996 --- util.c Sun Jul 21 21:51:38 1996 *** 106,111 **** --- 108,114 ---- if (insize == 0) { if (eof_ok) return EOF; + flush_window(); read_error(); } bytes_in += (ulg)insize; E-mail: christos@astron.com Phone: Do not even think of telephoning me about this program.

From Kees Zeelenberg File 3.33 is available from Simtelnet and its mirrors: ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2apps/file333b.zip Documentation and sources are available from the same folder. File determines the file type of a given file. It is an implementation of the Unix file(1) command. It knows the 'magic number' of some 4000 files.
