65 .sp
66 .LP
67 The \fBfile\fR utility performs a series of tests on each file supplied by
68 \fIfile\fR and, optionally, on each file listed in \fIffile\fR in an attempt to
69 classify it. If the file is not a regular file, its file type is identified.
70 The file types directory, \fBFIFO\fR, block special, and character special are
71 identified as such. If the file is a regular file and the file is zero-length,
72 it is identified as an empty file.
73 .sp
74 .LP
75 If \fIfile\fR appears to be a text file, \fBfile\fR examines the first 512
76 bytes and tries to determine its programming language. If \fIfile\fR is a
89 By default, \fBfile\fR will try to use the localized magic file
90 \fB/usr/lib/locale/\fIlocale\fR/LC_MESSAGES/magic\fR, if it exists, to identify
91 files that have a magic number. For example, in the Japanese locale, \fBfile\fR
92 will try to use \fB/usr/lib/locale/ja/LC_MESSAGES/magic\fR. If a localized
93 magic file does not exist, \fBfile\fR will utilize \fB/etc/magic\fR. A magic
94 number is a numeric or string constant that indicates the file type. See
95 \fBmagic\fR(4) for an explanation of the format of \fB/etc/magic\fR.
96 .sp
97 .LP
98 If \fIfile\fR does not exist, cannot be read, or its file status could not be
99 determined, it is not considered an error that affects the exit status. The
100 output will indicate that the file was processed, but that its type could not
101 be determined.
