Maintenance notes:
I am continuing to maintain the file command. I welcome your help,
but to make my life easier I'd like to request the following:
- Don't change the version numbers!
If your changes are extensive, I will have to work hard to
integrate them into my version. If you check it into SCCS locally,
the version numbers will likely be kept. IF you check it into RCS
or CVS locally, please use -k to keep the version numbers, and
please use branch deltas (1.21.1, 1.21.2, ...). If you don't do
this, I will likely be unable to use your changes; life's just too
short.
- Do not distribute changed versions.
People trying to be helpful occasionally put up their hacked versions
of the file command for FTP, then the "archie" server finds and publishes
the hacked version, and people all over the world get copies of it.
Within a day or two I am getting email from around the world
asking me why "my" file command won't compile!!! Needless to say this
detracts from the limited time I have available to work on the actual
software. Therefore I ask you again to please NOT distribute
your changed version.
Thank you for your assistance and cooperation.

# XXX - somebody should figure out whether any byte order needs to be
# applied to the "TML" stuff; I'm assuming the Apollo stuff is
# big-endian as it was mostly 68K-based.
#
# HP-PA is big-endian, so it (and "800", which is *also* HP-PA-based; I
# assume "HPPA-RISC1.1" really means "HP-PA Version 1.1", which first
# showed up in the 700 series, although later 800 series machines are,
# I think, based on the PA7100 which implements HP-PA 1.1) are flagged
# as big-endian.
#
# I think the 500 series was the old stack-based machines, running a
# UNIX environment atop the "SUN kernel"; dunno whether it was
# big-endian or little-endian.
#
# I'm guessing that the 200 series was 68K-based; the 300 and 400 series
# are.
#
# The "misc" stuff needs a byte order; the archives look suspiciously
# like the old 177545 archives (0xff65 = 0177545).

Portability of the new file(1) command.
@(#) $Id: PORTING,v 1.11 1993/09/23 21:47:23 christos Exp $
Read this file only if the program doesn't compile on your system.
This release has been around UNIX; it has been compiled and tested
in the following environments:
SunOS sqarc 4.1.1 8 sun4
No problems.
ULTRIX squint 4.2 0 RISC
No problems.
A/UX sqmac 3.0a9 SVR22 mc68020
No problems.
AIX sqibm 2 3 000XXXXXX100
Had weird "make" problems making "magic" file automatically; just
built it by hand. Your mileage may vary.
SCO sqwang 3.2 2 i386
Compiles fine; their weird make can't handle "[a-z]*" as a dependancy,
so build magic by hand. Runs fine.
sqzme sqzme 3.1.1 3 3B2
The 3B2 SVR3 needed a few tweaks as well as COPTS = -Ilocalinc
in order to compile.
This version, reluctanly, includes <stdlib.h>, which won't exist
on older systems or those that aren't even close to the ANSI C
standard. There is a null "stdlib.h", and some other bogus headers,
in subdirectory "localinc"; if you get complaints about missing
stdlib.h and others, uncomment the line with COPTS=-Ilocalinc
in the Makefile, and try again.
You must have either <stdarg.h> or the older <varargs.h>, otherwise you'll
have to butcher some routines in print.c.
Beyond that, I have tried to make a program that doesn't need any
command-line defines (-D) to specify what version of UNIX is in use,
by using the definitions available in the system #include
files. For example, the lstat(2) call is normally found in
4BSD systems, but might be grafted into some other variant
of UNIX. If it's done right (ie., using the same definitions),
my program will compile and work correctly. Look at the #ifdefs
to see how it's done.
I've also tried to include source for all the non-portable library routines
I used (getopt, str*). Non-portable here means `not in every
reasonably standard UNIX out there: V7, System V, 4BSD'.
These are in subdirectory "localsrc", and not used unless you
need them; again, see the Makefile.
There is one area that just might cause problems. On System
V, they moved the definition of major() and minor() out of
<sys/types.h> into <sys/sysmacros.h>. Hence, if major isn't
defined after including types.h, I automatically include sys/sysmacros.h.
This will work for 99% of the systems out there. ONLY if you
have a system in which neither types.h nor sysmacros.h defines
`major' will this automatic include fail (I hope). On such
systems, you will get a compilation error in trying to compile
a warning message. Please do the following:
1) change the appropriate #include at the start of fsmagic.c
and 2) let me know the name of the system, the release number,
and the name of the header file that *does* include
this "standard" definition.
If you are running the old Ritchie PDP-11 C compiler or
some other compiler that doesn't know about `void', you will have
to include `-Dvoid=int' in the variable COPTS in the Makefile.
Other than this, there should be no portability problems,
but one never knows these days. Please let me know of any
other problems you find porting to a UNIX system. I don't much
care about non-UNIX systems but will collect widely-used magic
numbers for them as well as for UNIX systems.

** README for file(1) Command **
@(#) $Id: README,v 1.20 1993/09/23 21:47:01 christos Exp $
This is Release 3.x of Ian Darwin's (copyright but distributable)
file(1) command. Release 3.x is scheduled for inclusion in the
4.4 BSD (Berkeley Software Distribution) of UNIX-like
software, and is the standard "file" command for Linux, 386bsd,
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 - 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
strtok.c, getopt.c - in case you them (courtesy of Henry Spencer).
strtol.c, strchr.c - in case you need them - public domain.
tst - simple test suite, built from tst/Makefile

.Nm file
.Op Fl h
.Ar file ...
.Sh DESCRIPTION
.Nm File
tests the specified files and attempts to classify them.
If a file is a text file,
it attempts to determine the type of text (e.g.
.Xr csh 1
commands or C source code).
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl h
If a symbolic link is specified, identify the file as a symbolic
link.
By default, symbolic links are only identified if they reference
non-existent files.
.El
.Sh COMPATIBILITY
Previous implementations of the
.Nm file
utility did not follow symbolic links by default.
.Sh BUGS
As many tests are used and
.Nm file
stops testing on the first successful one, it can often make mistakes.
.Sh HISTORY

tests each argument in an attempt to classify it.
There are three sets of tests, performed in this order:
filesystem tests, magic number tests, and language tests.
The
.I first
test that succeeds causes the file type to be printed.
.PP
The type printed will usually contain one of the words
.B text
(the file contains only ASCII characters and is
probably safe to read on an ASCII terminal),
.B executable
(the file contains the result of compiling a program
in a form understandable to some \s-1UNIX\s0 kernel or another),
or
.B data
meaning anything else (data is usually `binary' or non-printable).
Exceptions are well-known file formats (core files, tar archives)
that are known to contain binary data.
When modifying the file
.I __MAGIC__
or the program itself,
.B "preserve these keywords" .
People depend on knowing that all the readable files in a directory
have the word ``text'' printed.
Don't do as Berkeley did \- change ``shell commands text''
to ``shell script''.
.PP
The filesystem tests are based on examining the return from a
.IR stat (2)
system call.
The program checks to see if the file is empty,
or if it's some sort of special file.
Any known file types appropriate to the system you are running on
(sockets, symbolic links, or named pipes (FIFOs) on those systems that
implement them)
are intuited if they are defined in
the system header file
.BR sys/stat.h .
.PP
The magic number tests are used to check for files with data in
particular fixed formats.
The canonical example of this is a binary executable (compiled program)
.B a.out
file, whose format is defined in
.B a.out.h
and possibly
.B exec.h
in the standard include directory.
These files have a `magic number' stored in a particular place
near the beginning of the file that tells the \s-1UNIX\s0 operating system
that the file is a binary executable, and which of several types thereof.
The concept of `magic number' has been applied by extension to data files.
Any file with some invariant identifier at a small fixed
offset into the file can usually be described in this way.
The information in these files is read from the magic file
.I __MAGIC__.
.PP
If an argument appears to be an
.SM ASCII
file,
.I file
attempts to guess its language.
The language tests look for particular strings (cf \fInames.h\fP)
that can appear anywhere in the first few blocks of a file.
For example, the keyword
.B .br
indicates that the file is most likely a troff input file,
just as the keyword
.B struct
indicates a C program.
These tests are less reliable than the previous
two groups, so they are performed last.
The language test routines also test for some miscellany
(such as
.I tar
archives) and determine whether an unknown file should be
labelled as `ascii text' or `data'.
.PP
Use
.B \-m
.I file
to specify an alternate file of magic numbers.
.PP
The
.B \-z
tries to look inside compressed files.
.PP
The
.B \-c
option causes a checking printout of the parsed form of the magic file.
This is usually used in conjunction with
.B \-m
to debug a new magic file before installing it.
.PP
The
.B \-f
.I namefile
option specifies that the names of the files to be examined
are to be read (one per line) from
.I namefile
before the argument list.
Either
.I namefile
or at least one filename argument must be present;
to test the standard input, use ``-'' as a filename argument.
.PP
The
.B \-L
option causes symlinks to be followed, as the like-named option in
.IR ls (1).
.SH FILES
.I __MAGIC__
\- default list of magic numbers
.SH SEE ALSO

\- tools for examining non-textfiles.
.SH STANDARDS CONFORMANCE
This program is believed to exceed the System V Interface Definition
of FILE(CMD), as near as one can determine from the vague language
contained therein.
Its behaviour is mostly compatible with the System V program of the same name.
This version knows more magic, however, so it will produce
different (albeit more accurate) output in many cases.
.PP
The one significant difference
between this version and System V
is that this version treats any white space
as a delimiter, so that spaces in pattern strings must be escaped.
For example,
.br
>10 string language impress\ (imPRESS data)
.br
in an existing magic file would have to be changed to
.br
>10 string language\e impress (imPRESS data)
.br
In addition, in this version, if a pattern string contains a backslash,
it must be escaped. For example
.br
0 string \ebegindata Andrew Toolkit document
.br
in an existing magic file would have to be changed to
.br
0 string \e\ebegindata Andrew Toolkit document
.br
.PP
SunOS releases 3.2 and later from Sun Microsystems include a
.IR file (1)
command derived from the System V one, but with some extensions.
My version differs from Sun's only in minor ways.
It includes the extension of the `&' operator, used as,
for example,
.br
>16 long&0x7fffffff >0 not stripped
.SH MAGIC DIRECTORY
The magic file entries have been collected from various sources,
mainly USENET, and contributed by various authors.
Christos Zoulas (address below) will collect additional
or corrected magic file entries.
A consolidation of magic file entries
will be distributed periodically.
.PP
The order of entries in the magic file is significant.
Depending on what system you are using, the order that
they are put together may be incorrect.
If your old
.I file
command uses a magic file,
keep the old magic file around for comparison purposes
(rename it to
.IR __MAGIC__.orig ).
.SH HISTORY
There has been a
.I file
command in every UNIX since at least Research Version 6
(man page dated January, 1975).
The System V version introduced one significant major change:
the external list of magic number types.
This slowed the program down slightly but made it a lot more flexible.
.PP
This program, based on the System V version,
was written by Ian Darwin without looking at anybody else's source code.
.PP
John Gilmore revised the code extensively, making it better than
the first version.
Geoff Collyer found several inadequacies
and provided some magic file entries.
The program has undergone continued evolution since.

.PP
Altered by Rob McMahon, cudcv@warwick.ac.uk, 1989, to extend the `&' operator
from simple `x&y != 0' to `x&y op z'.
.PP
Altered by Guy Harris, guy@auspex.com, 1993, to:
.RS
.PP
put the ``old-style'' `&'
operator back the way it was, because 1) Rob McMahon's change broke the
previous style of usage, 2) the SunOS ``new-style'' `&' operator,
which this version of
.I file
supports, also handles `x&y op z', and 3) Rob's change wasn't documented
in any case;
.PP
put in multiple levels of `>';
.PP
put in ``beshort'', ``leshort'', etc. keywords to look at numbers in the
file in a specific byte order, rather than in the native byte order of
the process running
.IR file .

.SH BUGS
There must be a better way to automate the construction of the Magic
file from all the glop in Magdir. What is it?
Better yet, the magic file should be compiled into binary (say,
.IR ndbm (3)
or, better yet, fixed-length ASCII strings
for use in heterogenous network environments) for faster startup.
Then the program would run as fast as the Version 7 program of the same name,
with the flexibility of the System V version.
.PP
.I File
uses several algorithms that favor speed over accuracy,
thus it can be misled about the contents of ASCII files.
.PP
The support for ASCII files (primarily for programming languages)
is simplistic, inefficient and requires recompilation to update.
.PP
There should be an ``else'' clause to follow a series of continuation lines.
.PP
The magic file and keywords should have regular expression support.
Their use of ASCII TAB as a field delimiter is ugly and makes
it hard to edit the files, but is entrenched.
.PP
It might be advisable to allow upper-case letters in keywords
for e.g., troff commands vs man page macros.
Regular expression support would make this easy.
.PP
The program doesn't grok \s-2FORTRAN\s0.
It should be able to figure \s-2FORTRAN\s0 by seeing some keywords which
appear indented at the start of line.
Regular expression support would make this easy.
.PP
The list of keywords in
.I ascmagic
probably belongs in the Magic file.
This could be done by using some keyword like `*' for the offset value.
.PP
Another optimisation would be to sort
the magic file so that we can just run down all the
tests for the first byte, first word, first long, etc, once we
have fetched it. Complain about conflicts in the magic file entries.
Make a rule that the magic entries sort based on file offset rather
than position within the magic file?
.PP
The program should provide a way to give an estimate
of ``how good'' a guess is.
We end up removing guesses (e.g. ``From '' as first 5 chars of file) because
they are not as good as other guesses (e.g. ``Newsgroups:'' versus
"Return-Path:"). Still, if the others don't pan out, it should be
possible to use the first guess.
.PP
This program is slower than some vendors' file commands.
.PP
This manual page, and particularly this section, is too long.

.TH MAGIC __SECTION__ "Public Domain"
.\" install as magic.4 on USG, magic.5 on V7 or Berkeley systems.
.SH NAME
magic \- file command's magic number file
.SH DESCRIPTION
The
.IR file (1)
command identifies the type of a file using,
among other tests,
a test for whether the file begins with a certain
.IR "magic number" .
The file
.B __MAGIC__
specifies what magic numbers are to be tested for,
what message to print if a particular magic number is found,
and additional information to extract from the file.
.PP
Each line of the file specifies a test to be performed.
A test compares the data starting at a particular offset
in the file with a 1-byte, 2-byte, or 4-byte numeric value or
a string. If the test succeeds, a message is printed.
The line consists of the following fields:
.IP offset \w'message'u+2n
A number specifying the offset, in bytes, into the file of the data
which is to be tested.
.IP type
The type of the data to be tested. The possible values are:
.RS
.IP byte \w'message'u+2n
A one-byte value.
.IP short
A two-byte value (on most systems) in this machine's native byte order.
.IP long
A four-byte value (on most systems) in this machine's native byte order.
.IP string
A string of bytes.
.IP date
A four-byte value interpreted as a unix date.
.IP beshort
A two-byte value (on most systems) in big-endian byte order.
.IP belong
A four-byte value (on most systems) in big-endian byte order.
.IP bedate
A four-byte value (on most systems) in big-endian byte order,
interpreted as a unix date.
.IP leshort
A two-byte value (on most systems) in little-endian byte order.
.IP lelong
A four-byte value (on most systems) in little-endian byte order.
.IP ledate
A four-byte value (on most systems) in little-endian byte order,
interpreted as a unix date.
.RE
.PP
The numeric types may optionally be followed by
.B &
and a numeric value,
to specify that the value is to be AND'ed with the
numeric value before any comparisons are done. Prepending a
.B u
to the type indicates that ordered comparisons should be unsigned.
.IP test
The value to be compared with the value from the file. If the type is
numeric, this value
is specified in C form; if it is a string, it is specified as a C string
with the usual escapes permitted (e.g. \en for new-line).
.IP
Numeric values
may be preceded by a character indicating the operation to be performed.
It may be
.BR = ,
to specify that the value from the file must equal the specified value,
.BR < ,
to specify that the value from the file must be less than the specified
value,
.BR > ,
to specify that the value from the file must be greater than the specified
value,
.BR & ,
to specify that the value from the file must have set all of the bits
that are set in the specified value,
or
.BR ^ ,
to specify that the value from the file must have clear any of the bits
that are set in the specified value.
.IP
Numeric values are specified in C form; e.g.
.B 13
is decimal,
.B 013
is octal, and
.B 0x13
is hexadecimal.
to specify that any value will match. If the character
is omitted, it is assumed to be
.BR = .
.IP
For string values, the byte string from the
file must match the specified byte string.
The operators
.BR = ,
.B <
and
.B >
(but not
.BR & )
can be applied to strings.
The length used for matching is that of the string argument
in the magic file. This means that a line can match any string, and
then presumably print that string, by doing
.B >\e0
(because all strings are greater than the null string).
.IP message
The message to be printed if the comparison succeeds. If the string
contains a
.IR printf (3S)
format specification, the value from the file (with any specified masking
performed) is printed using the message as the format string.
.PP
Some file formats contain additional information which is to be printed
along with the file type. A line which begins with the character
.B >
indicates additional tests and messages to be printed. The number of
.B >
on the line indicates the level of the test; a line with no
.B >
at the beginning is considered to be at level 0.
Each line at level
.IB n \(pl1
is under the control of the line at level
.IB n
most closely preceding it in the magic file.
If the test on a line at level
.I n
succeeds, the tests specified in all the subsequent lines at level
.IB n \(pl1
are performed, and the messages printed if the tests succeed. The next
line at level
.I n
terminates this.
If the first character following the last
.B >
is a
.B (
then the string after the parenthesis is interpreted as an indirect offset.
That means that the number after the parenthesis is used as a offset in
the file. The value at that offset is read, and is used again as an offset
in the file. Indirect offsets are of the form:
.BI (( x [.[bsl]][+-][ y ]).
The value of
.I x
is used as an offset in the file. A byte, short or long is read at that offset
depending on the
.B [bsl]
type specifier. To that number the value of
.I y
is added and the result is used as an offset in the file. The default type
if one is not specified is long.
.SH BUGS
The formats
.IR long ,
.IR belong ,
.IR lelong ,
.IR short ,
.IR beshort ,
.IR leshort ,
.IR date ,
.IR bedate ,
and
.I ledate
are system-dependant; perhaps they should be specified as a number
of bytes (2B, 4B, etc),
since the files being recognized typically come from
a system on which the lengths are invariant.
.PP
There is (currently) no support for specified-endian data to be used in
indirect offsets.
