50 .SH NAME
51 find \- find files
52 .SH SYNOPSIS
53 .LP
54 .nf
55 \fB/usr/bin/find\fR [\fB-E\fR] [\fB-H\fR | \fB-L\fR] \fIpath\fR... \fIexpression\fR

61 .fi
62
63 .SH DESCRIPTION
64 .sp
65 .LP
66 The \fBfind\fR utility recursively descends the directory hierarchy for each
67 \fIpath\fR seeking files that match a Boolean \fIexpression\fR written in the
68 primaries specified below.
69 .sp
70 .LP
71 \fBfind\fR is able to descend to arbitrary depths in a file hierarchy and does
72 not fail due to path length limitations (unless a \fIpath\fR operand specified
73 by the application exceeds \fIPATH_MAX\fR requirements).
74 .sp
75 .LP
76 \fBfind\fR detects infinite loops; that is, entering a previously visited
77 directory that is an ancestor of the last file encountered.
78 .SH OPTIONS
79 .sp
80 .LP
81 The following options are supported:
82 .sp
83 .ne 2
84 .na
85 \fB\fB-E\fR\fR
86 .ad
87 .RS 6n
88 Interpret regular expressions followed by \fB-regex\fR and \fB-iregex\fR
89 primaries as extended regular expressions.

91
92 .sp
93 .ne 2
94 .na
95 \fB\fB-H\fR\fR
96 .ad
97 .RS 6n
98 Causes the file information and file type evaluated for each symbolic link
99 encountered on the command line to be those of the file referenced by the link,
100 and not the link itself. If the referenced file does not exist, the file
101 information and type is for the link itself. File information for all symbolic
102 links not on the command line is that of the link itself.
103 .RE
104
105 .sp
106 .ne 2
107 .na
108 \fB\fB-L\fR\fR
109 .ad
110 .RS 6n
111 Causes the file information and file type evaluated for each symbolic link to
112 be those of the file referenced by the link, and not the link itself. See
113 \fBNOTES\fR.
114 .RE
115
116 .sp
117 .LP
118 Specifying more than one of the mutually-exclusive options \fB-H\fR and
119 \fB-L\fR is not considered an error. The last option specified determines the
120 behavior of the utility.

141 and all subsequent arguments are interpreted as an \fIexpression\fR made up of
142 the following primaries and operators. In the descriptions, wherever \fIn\fR is
143 used as a primary argument, it is interpreted as a decimal integer optionally
144 preceded by a plus (\fB+\fR) or minus (\fB\(mi\fR) sign, as follows:

237 \fB\fB-depth\fR\fR
238 .ad
239 .RS 17n
240 Always true. Causes descent of the directory hierarchy to be done so that all
241 entries in a directory are acted on before the directory itself. This can be
242 useful when \fBfind\fR is used with \fBcpio\fR(1) to transfer files that are
243 contained in directories without write permission.

249 \fB\fB-exec\fR \fIcommand\fR\fR
250 .ad
251 .RS 17n
252 True if the executed command returns a zero value as exit status. The end of
253 command must be punctuated by an escaped semicolon (\fB;\fR). A command
254 argument \fB{}\fR is replaced by the current pathname. If the last argument to
255 \fB-exec\fR is \fB{}\fR and you specify \fB+\fR rather than the semicolon
256 (\fB;\fR), the command is invoked fewer times, with \fB{}\fR replaced by groups
257 of pathnames. If any invocation of the command returns a non-zero value as exit
258 status, find returns a non-zero exit status.

264 \fB\fB-follow\fR\fR
265 .ad
266 .RS 17n
267 Always true and always evaluated no matter where it appears in
268 \fIexpression\fR. The behavior is unspecified if \fB-follow\fR is used when the
269 \fBfind\fR command is invoked with either the \fB-H\fR or the \fB-L\fR option.
270 Causes symbolic links to be followed. When following symbolic links, \fBfind\fR
271 keeps track of the directories visited so that it can detect infinite loops.
272 For example, such a loop would occur if a symbolic link pointed to an ancestor.

1096 When using \fBfind\fR to determine files modified within a range of time, use

1098 \fBfind\fR gives all files.
1099 .sp
1100 .LP
1101 Some files that might be under the Solaris root file system are actually mount
1102 points for virtual file systems, such as \fBmntfs\fR or \fBnamefs\fR. When
1103 comparing against a \fBufs\fR file system, such files are not selected if
1104 \fB-mount\fR or \fB-xdev\fR is specified in the \fBfind\fR expression.
1105 .sp
1106 .LP
1107 Using the \fB-L\fR or \fB-follow\fR option is not recommended when descending a
1108 file-system hierarchy that is under the control of other users. In particular,
1109 when using \fB-exec\fR, symbolic links can lead the \fBfind\fR command out of
1110 the hierarchy in which it started. Using \fB-type\fR is not sufficient to
1111 restrict the type of files on which the \fB-exec\fR command operates, because
1112 there is an inherent race condition between the type-check performed by the
1113 \fBfind\fR command and the time the executed command operates on the file
1114 argument.
