64 64 .SH DESCRIPTION
65 65 .sp
66 66 .LP
67 67 The \fBfile\fR utility performs a series of tests on each file supplied by
68 68 \fIfile\fR and, optionally, on each file listed in \fIffile\fR in an attempt to
69 69 classify it. If the file is not a regular file, its file type is identified.
70 70 The file types directory, \fBFIFO\fR, block special, and character special are
71 71 identified as such. If the file is a regular file and the file is zero-length,
72 72 it is identified as an empty file.
73 73 .sp
74 74 .LP
75 75 If \fIfile\fR appears to be a text file, \fBfile\fR examines the first 512
76 76 bytes and tries to determine its programming language. If \fIfile\fR is a
77 77 symbolic link, by default the link is followed and \fBfile\fR tests the file to
78 78 which the symbolic link refers.
79 79 .sp
80 80 .LP
81 81 If \fIfile\fR is a relocatable object, executable, or shared object, \fBfile\fR
82 82 prints out information about the file's execution requirements. This
83 83 information includes the machine class, byte-ordering, static/dynamic linkage,
84 84 and any software or hardware capability requirements. If \fIfile\fR is a
85 85 runtime linking configuration file, \fBfile\fR prints information about the
86 86 target platform, including the machine class and byte-ordering.
87 87 .sp
88 88 .LP
89 89 By default, \fBfile\fR will try to use the localized magic file
90 90 \fB/usr/lib/locale/\fIlocale\fR/LC_MESSAGES/magic\fR, if it exists, to identify
91 91 files that have a magic number. For example, in the Japanese locale, \fBfile\fR
92 92 will try to use \fB/usr/lib/locale/ja/LC_MESSAGES/magic\fR. If a localized
93 93 magic file does not exist, \fBfile\fR will utilize \fB/etc/magic\fR. A magic
94 94 number is a numeric or string constant that indicates the file type. See
95 95 \fBmagic\fR(4) for an explanation of the format of \fB/etc/magic\fR.
96 96 .sp
97 97 .LP
98 98 If \fIfile\fR does not exist, cannot be read, or its file status could not be
99 99 determined, it is not considered an error that affects the exit status. The
100 100 output will indicate that the file was processed, but that its type could not
101 101 be determined.
102 102 .SH OPTIONS

110 110 .ad
111 111 .RS 12n
112 112 Checks the magic file for format errors. For reasons of efficiency, this
113 113 validation is normally not carried out.

123 123 the file.

139 139 .ad
140 140 .RS 12n
141 141 When a symbolic link is encountered, this option identifies the file as a
142 142 symbolic link. If \fB-h\fR is not specified and \fIfile\fR is a symbolic link
143 143 that refers to a non-existent file, the \fBfile\fR utility identifies the file
144 144 as a symbolic link, as if \fB-h\fR had been specified.

151 151 .ad
152 152 .RS 12n
153 153 If a file is a regular file, this option does not attempt to classify the type
154 154 of file further, but identifies the file as a "regular file".

178 178 Specifies the name of a file containing position-sensitive tests that are
179 179 applied to a file in order to classify it (see \fBmagic\fR(4)). If the \fB-m\fR
180 180 option is specified without specifying the \fB-d\fR option or the \fB-M\fR
181 181 option, position-sensitive default system tests are applied after the
182 182 position-sensitive tests specified by the \fB-m\fR option.

193 193 Specifies the name of a file containing position-sensitive tests that are
194 194 applied to a file in order to classify it (see \fBmagic\fR(4)). No
195 195 position-sensitive default system tests nor context-sensitive default system
196 196 tests are applied unless the \fB-d\fR option is also specified.

200 200 .LP
201 201 If the \fB-M\fR option is specified with the \fB-d\fR option, the \fB-m\fR
202 202 option, or both, or if the \fB-m\fR option is specified with the \fB-d\fR
203 203 option, the concatenation of the position-sensitive tests specified by these
204 204 options is applied in the order specified by the appearance of these options.
