.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
utility tests each argument in an attempt to classify it.
|
||||
There are three sets of tests, performed in this order:
|
||||
filesystem tests, magic tests, and language tests.
|
||||
The first test that succeeds causes the file type to be printed.
|
||||
.Pp
|
||||
The type printed will usually contain one of the words
|
||||
.Em text
|
||||
(the file contains only
|
||||
printing characters and a few common control
|
||||
characters and is probably safe to read on an
|
||||
ASCII terminal),
|
||||
.Em executable
|
||||
(the file contains the result of compiling a program
|
||||
in a form understandable to some
|
||||
.Ux
|
||||
kernel or another),
|
||||
or
|
||||
.Em data
|
||||
meaning anything else (data is usually
|
||||
.Dq binary
|
||||
or non-printable).
|
||||
Exceptions are well-known file formats (core files, tar archives)
|
||||
that are known to contain binary data.
|
||||
When modifying magic files or the program itself, make sure to
|
||||
.Em preserve these keywords .
|
||||
Users depend on knowing that all the readable files in a directory
|
||||
have the word
|
||||
.Dq text
|
||||
printed.
|
||||
Don't do as Berkeley did and change
|
||||
.Dq shell commands text
|
||||
to
|
||||
.Dq shell script .
|
||||
.Pp
|
||||
The filesystem tests are based on examining the return from a
|
||||
.Xr 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,
|
||||
such as sockets, symbolic links, and named pipes (FIFOs),
|
||||
are intuited if they are defined in
|
||||
the system header file
|
||||
.Aq Pa sys/stat.h .
|
||||
.Pp
|
||||
The magic tests are used to check for files with data in
|
||||
particular fixed formats.
|
||||
The canonical example of this is a binary executable (compiled program)
|
||||
a.out file, whose format is defined in
|
||||
.Aq Pa elf.h ,
|
||||
.Aq Pa a.out.h ,
|
||||
and possibly
|
||||
.Aq Pa exec.h
|
||||
in the standard include directory.
|
||||
These files have a
|
||||
.Dq magic number
|
||||
stored in a particular place
|
||||
near the beginning of the file that tells the
|
||||
.Ux
|
||||
operating system
|
||||
that the file is a binary executable, and which of several types thereof.
|
||||
The concept of a
|
||||
.Dq magic
|
||||
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 identifying these files is read from the magic file
|
||||
.Pa /etc/magic .
|
||||
In addition, if
|
||||
.Pa $HOME/.magic.mgc
|
||||
or
|
||||
.Pa $HOME/.magic
|
||||
exists, it will be used in preference to the system magic files.
|
||||
.Pp
|
||||
If a file does not match any of the entries in the magic file,
|
||||
it is examined to see if it seems to be a text file.
|
||||
ASCII, ISO-8859-x, non-ISO 8-bit extended-ASCII character sets
|
||||
(such as those used on Macintosh and IBM PC systems),
|
||||
UTF-8-encoded Unicode, UTF-16-encoded Unicode, and EBCDIC
|
||||
character sets can be distinguished by the different
|
||||
ranges and sequences of bytes that constitute printable text
|
||||
in each set.
|
||||
If a file passes any of these tests, its character set is reported.
|
||||
ASCII, ISO-8859-x, UTF-8, and extended-ASCII files are identified
|
||||
as
|
||||
.Dq text
|
||||
because they will be mostly readable on nearly any terminal;
|
||||
UTF-16 and EBCDIC are only
|
||||
.Dq character data
|
||||
because, while
|
||||
they contain text, it is text that will require translation
|
||||
before it can be read.
|
||||
In addition,
|
||||
.Nm
|
||||
will attempt to determine other characteristics of text-type files.
|
||||
If the lines of a file are terminated by CR, CRLF, or NEL, instead
|
||||
of the Unix-standard LF, this will be reported.
|
||||
Files that contain embedded escape sequences or overstriking
|
||||
will also be identified.
|
||||
.Pp
|
||||
Once
|
||||
.Nm
|
||||
has determined the character set used in a text-type file,
|
||||
it will
|
||||
attempt to determine in what language the file is written.
|
||||
The language tests look for particular strings (cf.\&
|
||||
.Aq Pa names.h )
|
||||
that can appear anywhere in the first few blocks of a file.
|
||||
For example, the keyword
|
||||
.Em .br
|
||||
indicates that the file is most likely a
|
||||
troff input file, just as the keyword
|
||||
.Em 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
|
||||
.Xr tar 1
|
||||
archives).
|
||||
.Pp
|
||||
Any file that cannot be identified as having been written
|
||||
in any of the character sets listed above is simply said to be
|
||||
.Dq data .
|
||||
.Sh OPTIONS
|
||||
.Bl -tag -width indent
|
||||
.It Fl 0 , -print0
|
||||
Output a null character
|
||||
.Sq \e0
|
||||
after the end of the filename.
|
||||
Nice to
|
||||
.Xr cut 1
|
||||
the output.
|
||||
This does not affect the separator which is still printed.
|
||||
.It Fl b , -brief
|
||||
Do not prepend filenames to output lines (brief mode).
|
||||
.It Fl C , -compile
|
||||
Write a
|
||||
.Pa magic.mgc
|
||||
output file that contains a pre-parsed version of the magic file or directory.
|
||||
.It Fl c , -checking-printout
|
||||
Cause a checking printout of the parsed form of the magic file.
|
||||
This is usually used in conjunction with the
|
||||
.Fl m
|
||||
flag to debug a new magic file before installing it.
|
||||
.It Fl e , -exclude Ar testname
|
||||
Exclude the test named in
|
||||
.Ar testname
|
||||
from the list of tests made to determine the file type.
|
||||
Valid test names are:
|
||||
.Bl -tag -width compress
|
||||
.It apptype
|
||||
Check for
|
||||
.Dv EMX
|
||||
application type (only on EMX).
|
||||
.It ascii
|
||||
Check for various types of ASCII files.
|
||||
.It compress
|
||||
Don't look for, or inside, compressed files.
|
||||
.It elf
|
||||
Don't print elf details.
|
||||
.It fortran
|
||||
Don't look for fortran sequences inside ASCII files.
|
||||
.It soft
|
||||
Don't consult magic files.
|
||||
.It tar
|
||||
Don't examine tar files.
|
||||
.It token
|
||||
Don't look for known tokens inside ASCII files.
|
||||
.It troff
|
||||
Don't look for troff sequences inside ASCII files.
|
||||
.El
|
||||
.It Fl F , -separator Ar separator
|
||||
Use the specified string as the separator between the filename and the
|
||||
file result returned.
|
||||
Defaults to
|
||||
.Sq \&: .
|
||||
.It Fl f , -files-from Ar namefile
|
||||
Read the names of the files to be examined from
|
||||
.Ar namefile
|
||||
(one per line)
|
||||
before the argument list.
|
||||
Either
|
||||
.Ar namefile
|
||||
or at least one filename argument must be present;
|
||||
to test the standard input, use
|
||||
.Sq -
|
||||
as a filename argument.
|
||||
.It Fl h , -no-dereference
|
||||
Causes symlinks not to be followed.
|
||||
This is the default if the environment variable
|
||||
.Dv POSIXLY_CORRECT
|
||||
is not defined.
|
||||
.It Fl -help
|
||||
Print a help message and exit.
|
||||
.It Fl i , -mime
|
||||
Causes the file command to output mime type strings rather than the more
|
||||
traditional human readable ones.
|
||||
Thus it may say
|
||||
.Dq text/plain charset=us-ascii
|
||||
rather than
|
||||
.Dq ASCII text .
|
||||
In order for this option to work,
|
||||
.Nm
|
||||
changes the way it handles files recognized by the command itself
|
||||
(such as many of the text file types, directories etc.),
|
||||
and makes use of an alternative
|
||||
.Dq magic
|
||||
file.
|
||||
See also
|
||||
.Sx FILES ,
|
||||
below.
|
||||
.It Fl -mime-encoding , -mime-type
|
||||
Like
|
||||
.Fl i ,
|
||||
but print only the specified element(s).
|
||||
.It Fl k , -keep-going
|
||||
Don't stop at the first match, keep going.
|
||||
Subsequent matches will have the string
|
||||
.Dq "\[rs]012\- "
|
||||
prepended.
|
||||
(If a newline is required, see the
|
||||
.Fl r
|
||||
option.)
|
||||
.It Fl L , -dereference
|
||||
Causes symlinks to be followed;
|
||||
analogous to the option of the same name in
|
||||
.Xr ls 1 .
|
||||
This is the default if the environment variable
|
||||
.Dv POSIXLY_CORRECT
|
||||
is defined.
|
||||
.It Fl m , -magic-file Ar magicfiles
|
||||
Specify an alternate list of files and directories containing magic.
|
||||
This can be a single item, or a colon-separated list.
|
||||
If a compiled magic file is found alongside a file or directory,
|
||||
it will be used instead.
|
||||
.It Fl N , -no-pad
|
||||
Don't pad filenames so that they align in the output.
|
||||
.It Fl n , -no-buffer
|
||||
Force stdout to be flushed after checking each file.
|
||||
This is only useful if checking a list of files.
|
||||
It is intended to be used by programs that want filetype output from a pipe.
|
||||
.It Fl p , -preserve-date
|
||||
On systems that support
|
||||
.Xr utime 3
|
||||
or
|
||||
.Xr utimes 2 ,
|
||||
attempt to preserve the access time of files analyzed, to pretend that
|
||||
.Nm
|
||||
never read them.
|
||||
.It Fl r , -raw
|
||||
Don't translate unprintable characters to \eooo.
|
||||
Normally
|
||||
.Nm
|
||||
translates unprintable characters to their octal representation.
|
||||
.It Fl s , -special-files
|
||||
Normally,
|
||||
.Nm
|
||||
only attempts to read and determine the type of argument files which
|
||||
.Xr stat 2
|
||||
reports are ordinary files.
|
||||
This prevents problems, because reading special files may have peculiar
|
||||
consequences.
|
||||
Specifying the
|
||||
.Fl s
|
||||
option causes
|
||||
.Nm
|
||||
to also read argument files which are block or character special files.
|
||||
This is useful for determining the filesystem types of the data in raw
|
||||
disk partitions, which are block special files.
|
||||
This option also causes
|
||||
.Nm
|
||||
to disregard the file size as reported by
|
||||
.Xr stat 2
|
||||
since on some systems it reports a zero size for raw disk partitions.
|
||||
.It Fl v , -version
|
||||
Print the version of the program and exit.
|
||||
.It Fl z , -uncompress
|
||||
Try to look inside compressed files.
|
||||
.El
|
||||
.Sh ENVIRONMENT
|
||||
The environment variable
|
||||
.Dv MAGIC
|
||||
can be used to set the default magic file name.
|
||||
If that variable is set, then
|
||||
.Nm
|
||||
will not attempt to open
|
||||
.Pa $HOME/.magic .
|
||||
.Nm
|
||||
adds
|
||||
.Dq .mgc
|
||||
to the value of this variable as appropriate.
|
||||
The environment variable
|
||||
.Dv POSIXLY_CORRECT
|
||||
controls whether
|
||||
.Nm
|
||||
will attempt to follow symlinks or not.
|
||||
If set, then
|
||||
.Nm
|
||||
follows symlinks; otherwise it does not.
|
||||
This is also controlled by the
|
||||
.Fl L
|
||||
and
|
||||
.Fl h
|
||||
options.

.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 behavior 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.
|
||||
.\" URL: http://www.opengroup.org/onlinepubs/009695399/utilities/file.html
|
||||
.Pp
|
||||
The one significant difference
|
||||
between this version and System V
|
||||
is that this version treats any whitespace
|
||||
as a delimiter, so that spaces in pattern strings must be escaped.
|
||||
For example,
|
||||
.Bd -literal -offset indent
|
||||
\*(Gt10 string language impress\ (imPRESS data)
|
||||
.Ed
|
||||
.Pp
|
||||
in an existing magic file would have to be changed to
|
||||
.Bd -literal -offset indent
|
||||
\*(Gt10 string language\e impress (imPRESS data)
|
||||
.Ed
|
||||
.Pp
|
||||
In addition, in this version, if a pattern string contains a backslash,
|
||||
it must be escaped.
|
||||
For example
|
||||
.Bd -literal -offset indent
|
||||
0 string \ebegindata Andrew Toolkit document
|
||||
.Ed
|
||||
.Pp
|
||||
in an existing magic file would have to be changed to
|
||||
.Bd -literal -offset indent
|
||||
0 string \e\ebegindata Andrew Toolkit document
|
||||
.Ed
|
||||
.Pp
|
||||
SunOS releases 3.2 and later from Sun Microsystems include a
|
||||
.Nm
|
||||
command derived from the System V one, but with some extensions.
|
||||
This version differs from Sun's only in minor ways.
|
||||
It includes the extension of the
|
||||
.Sq &
|
||||
operator, used as,
|
||||
for example,
|
||||
.Bd -literal -offset indent
|
||||
\*(Gt16 long&0x7fffffff \*(Gt0 not stripped
|
||||
.Ed
|
||||
.Sh HISTORY
|
||||
There has been a
|
||||
.Nm
|
||||
command in every
|
||||
.Ux
|
||||
since at least Research Version 4
|
||||
(man page dated November, 1973).
|
||||
The System V version introduced one significant major change:
|
||||
the external list of magic 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.
|
||||
Contributions by the `&' operator by Rob McMahon, 1989.
|
||||
.Pp
|
||||
Guy Harris, made many changes from 1993 to the present.
|
||||
.Pp
|
||||
Primary development and maintenance from 1990 to the present by
|
||||
Christos Zoulas.
|
||||
.Pp
|
||||
Altered by Chris Lowth, 2000:
|
||||
Handle the
|
||||
.Fl i
|
||||
option to output mime type strings, using an alternative
|
||||
magic file and internal logic.
|
||||
.Pp
|
||||
Altered by Eric Fischer, July, 2000,
|
||||
to identify character codes and attempt to identify the languages
|
||||
of non-ASCII files.
|
||||
.Pp
|
||||
Altered by Reuben Thomas, 2007 to 2008, to improve MIME
|
||||
support and merge MIME and non-MIME magic, support directories as well
|
||||
as files of magic, apply many bug fixes and improve the build system.
|
||||
.Pp
|
||||
The list of contributors to the
|
||||
.Dq magic
|
||||
directory (magic files)
|
||||
is too long to include here.
|
||||
You know who you are; thank you.
|
||||
Many contributors are listed in the source files.
|
||||
.Sh BUGS
|
||||
.Pp
|
||||
There must be a better way to automate the construction of the Magic
|
||||
file from all the glop in Magdir.
|
||||
What is it?
|
||||
.Pp
|
||||
.Nm
|
||||
uses several algorithms that favor speed over accuracy,
|
||||
thus it can be misled about the contents of
|
||||
text
|
||||
files.
|
||||
.Pp
|
||||
The support for text files (primarily for programming languages)
|
||||
is simplistic, inefficient and requires recompilation to update.
|
||||
.Pp
|
||||
The list of keywords in
|
||||
.Pa ascmagic
|
||||
probably belongs in the Magic file.
|
||||
This could be done by using some keyword like
|
||||
.Sq *
|
||||
for the offset value.
|
||||
.Pp
|
||||
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
|
||||
.Dq how good
|
||||
a guess is.
|
||||
We end up removing guesses (e.g.
|
||||
.Dq From\
|
||||
as first 5 chars of file) because
|
||||
they are not as good as other guesses (e.g.\&
|
||||
.Dq Newsgroups:
|
||||
versus
|
||||
.Dq Return-Path: ) .
|
||||
Still, if the others don't pan out, it should be possible to use the
|
||||
first guess.
|
||||
.Pp
|
||||
This manual page, and particularly this section, is too long.
