1.1 root 1: .TH FIND 1
2: .CT 1 files dirs
3: .SH NAME
4: find \- find files
5: .SH SYNOPSIS
6: .B find
7: .I pathname ... expression
8: .SH DESCRIPTION
9: .I Find
10: recursively descends
11: the directory hierarchy for each
12: .I pathname,
13: seeking files that match a boolean
14: .I expression,
15: which consists of one or more arguments.
16: It does not follow symbolic links.
17: In the following descriptions of primary expressions,
18: .I n
19: is a decimal integer;
20: .BI + n
21: may be written to specify more than
22: .I n
23: and
24: .BI - n
25: to specify less.
26: .TP 10n
27: .BI -name " filename"
28: True if the
29: .I filename
30: argument matches the current file name.
31: Normal shell filename metacharacters may be used if quoted.
32: .TP
33: .BI -perm " onum"
34: True if the file permission flags
35: exactly
36: match the
37: octal number
38: .I onum
39: (see
40: .IR chmod (1)).
41: If
42: .I onum
43: is prefixed by a minus sign,
44: more mode bits (017777, see
45: .IR stat (2))
46: become significant and
47: the modes are compared:
48: .IR (mode&onum)==onum .
49: .TP
50: .BI -type " c"
51: True if the type of the file
52: is
53: .I c,
54: where
55: .I c
56: is
57: .BI b ", " c ", " d ", "
58: .BI f ", "
59: or
60: .B L
61: for
62: block special file, character special file,
63: directory, plain file or symbolic link.
64: .TP
65: .BI -links " n"
66: True if the file has
67: .I n
68: links.
69: .TP
70: .BI -user " uname"
71: True if the file belongs to the user
72: .I uname
73: (login name or numeric userid).
74: .TP
75: .BI -group " gname"
76: True if the file belongs to group
77: .I gname
78: (group name or numeric groupid).
79: .TP
80: .BI -size " n"
81: True if the file is
82: .I n
83: blocks long (512 bytes per block).
84: .TP
85: .BI -inum " n"
86: True if the file has inode number
87: .I n.
88: .TP
89: .BI -atime " n"
90: True if the file has been accessed in
91: .I n
92: days.
93: .TP
94: .BI -mtime " n"
95: True if the file has been modified in
96: .I n
97: days.
98: .TP
99: .BI -ctime " n"
100: True if the inode has been changed in
101: .I n
102: days.
103: .TP
104: .BI -exec " command"
105: True if the executed command returns
106: a zero value as exit status.
107: The end of the command must be punctuated by an escaped
108: semicolon.
109: A command argument
110: .L {}
111: is replaced by the
112: current pathname.
113: .TP
114: .BI -ok " command"
115: Like
116: .B -exec
117: except that the generated command is written on
118: the standard output, then the standard input is read
119: and the command executed only upon response
120: .BI y .
121: .TP
122: .B -print
123: Always true;
124: causes the current pathname to be printed.
125: .TP
126: .BI -newer " file"
127: True if
128: the file has been modified more recently than the argument
129: .I file.
130: .TP
131: .BI -status " n
132: True if
133: .IR lstat
134: (see
135: .IR stat (2))
136: applied to the file yields error number
137: .IR n ;
138: see
139: .IR intro (2).
140: Testing
141: .L -status
142: turns off diagnostics that errors normally produce.
143: On ordinary systems a nonzero error number occurs when a file
144: disappears underfoot or a file system is in trouble.
145: .PP
146: The following operators, listed in order of decreasing precedence,
147: may be used to combine primary expressions.
148: .TP
149: .BI ( " expression " )
150: Group with parentheses.
151: .TP
152: .BI ! " expression
153: Negation.
154: True if and only if
155: .I expression
156: is not true.
157: .TP
158: .I expression expression
159: Conjunction.
160: True if both expressions are true.
161: .TP
162: .IB expression " -o " expression
163: Disjunction.
164: True if either expression is true.
165: .SH EXAMPLES
166: .HP
167: .L
168: find / \e( -name a.out -o -name '*.o' \e) -atime +7 -exec rm '{}' \e;
169: .br
170: Remove all files named
171: .L a.out
172: or
173: .L *.o
174: that have not been accessed for a week.
