Add rcsid. RU#. Use err(3) instead of local redefinition. Convert man page to
mdoc format. Add usage(). Remove rcs $ Log $ -> use cvs log instead.

This manual page documents version 3.22 of the

command.
|

.B File

.Nm File
|
||||
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
|
||||
.Em first
|
||||
test that succeeds causes the file type to be printed.
|
||||
.PP
|
||||
.Pp
|
||||
The type printed will usually contain one of the words
|
||||
.B text
|
||||
.Em text
|
||||
(the file contains only
|
||||
.SM ASCII
|
||||
.Tn ASCII
|
||||
characters and is probably safe to read on an
|
||||
.SM ASCII
|
||||
.Tn ASCII
|
||||
terminal),
|
||||
.B executable
|
||||
.Em executable
|
||||
(the file contains the result of compiling a program
|
||||
in a form understandable to some \s-1UNIX\s0 kernel or another),
|
||||
in a form understandable to some
|
||||
.Ux
|
||||
kernel or another),
|
||||
or
|
||||
.B data
|
||||
.Em 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 /usr/share/misc/magic
|
||||
.Pa /usr/share/misc/magic
|
||||
or the program itself,
|
||||
.B "preserve these keywords" .
|
||||
.Em "preserve these keywords" .
|
||||
.Pp
|
||||
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
|
||||
.Pp
|
||||
The filesystem tests are based on examining the return from a
|
||||
.BR stat (2)
|
||||
.Xr stat 2
|
||||
system call.
|
||||
The program checks to see if the file is empty,
|
||||
or if it's some sort of special file.

|

.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)
|
||||
.I a.out
|
||||
.Pa a.out
|
||||
file, whose format is defined in
|
||||
.I a.out.h
|
||||
.Pa a.out.h
|
||||
and possibly
|
||||
.I exec.h
|
||||
.Pa 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
|
||||
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 `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 /usr/share/misc/magic.
|
||||
.PP
|
||||
.Pa /usr/share/misc/magic .
|
||||
.Pp
|
||||
If an argument appears to be an
|
||||
.SM ASCII
|
||||
.Tn ASCII
|
||||
file,
|
||||
.B file
|
||||
.Nm
|
||||
attempts to guess its language.
|
||||
The language tests look for particular strings (cf
|
||||
.IR names.h )
|
||||
.Pa names.h )
|
||||
that can appear anywhere in the first few blocks of a file.
|
||||
For example, the keyword
|
||||
.B .br
|
||||
.Em .br
|
||||
indicates that the file is most likely a
|
||||
.BR troff (1)
|
||||
.Xr troff 1
|
||||
input file, just as the keyword
|
||||
.B struct
|
||||
.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
|
||||
.BR tar (1)
|
||||
.Xr tar 1
|
||||
archives) and determine whether an unknown file should be
|
||||
labelled as `ascii text' or `data'.

.SH BUGS
|

.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,
|
||||
.BR ndbm (3)
|
||||
.Xr ndbm 3
|
||||
or, better yet, fixed-length
|
||||
.SM ASCII
|
||||
.Tn 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
|
||||
.B File
|
||||
.Pp
|
||||
.Nm File
|
||||
uses several algorithms that favor speed over accuracy,
|
||||
thus it can be misled about the contents of
|
||||
.SM ASCII
|
||||
.Tn ASCII
|
||||
files.
|
||||
.PP
|
||||
.Pp
|
||||
The support for
|
||||
.SM ASCII
|
||||
.Tn ASCII
|
||||
files (primarily for programming languages)
|
||||
is simplistic, inefficient and requires recompilation to update.
|
||||
.PP
|
||||
.Pp
|
||||
There should be an ``else'' clause to follow a series of continuation lines.
|
||||
.PP
|
||||
.Pp
|
||||
The magic file and keywords should have regular expression support.
|
||||
Their use of
|
||||
.SM "ASCII TAB"
|
||||
.Tn ASCII TAB
|
||||
as a field delimiter is ugly and makes
|
||||
it hard to edit the files, but is entrenched.
|
||||
.PP
|
||||
.Pp
|
||||
It might be advisable to allow upper-case letters in keywords
|
||||
for e.g.,
|
||||
.BR troff (1)
|
||||
.Xr troff 1
|
||||
commands vs man page macros.
|
||||
Regular expression support would make this easy.
|
||||
.PP
|
||||
.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
|
||||
.Pp
|
||||
The list of keywords in
|
||||
.I ascmagic
|
||||
.Em ascmagic
|
||||
probably belongs in the Magic file.
|
||||
This could be done by using some keyword like `*' for the offset value.
|
||||
.PP
|
||||
.Pp
|
||||
Another optimization 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
|
||||
.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.
