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

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.

139 148 .ad
140 149 .RS 12n
141 150 When a symbolic link is encountered, this option identifies the file as a
142 151 symbolic link. If \fB-h\fR is not specified and \fIfile\fR is a symbolic link
143 152 that refers to a non-existent file, the \fBfile\fR utility identifies the file
144 153 as a symbolic link, as if \fB-h\fR had been specified.

153 162 If a file is a regular file, this option does not attempt to classify the type
154 163 of file further, but identifies the file as a "regular file".

180 189 option is specified without specifying the \fB-d\fR option or the \fB-M\fR
181 190 option, position-sensitive default system tests are applied after the

195 204 position-sensitive default system tests nor context-sensitive default system
196 205 tests are applied unless the \fB-d\fR option is also specified.

202 211 option, or both, or if the \fB-m\fR option is specified with the \fB-d\fR
