1.1 root 1: .TH FIND 1 "18 January 1983"
2: .SH NAME
3: find \- find files
4: .SH SYNOPSIS
5: .B find
6: pathname-list expression
7: .SH DESCRIPTION
8: .I Find
9: recursively descends
10: the directory hierarchy for
11: each pathname in the
12: .I pathname-list
13: (i.e., one or more pathnames)
14: seeking files that match a boolean
15: .I expression
16: written in the primaries given below.
17: In the descriptions, the argument
18: .I n
19: is used as a decimal integer
20: where
21: .I +n
22: means more than
23: .I n,
24: .I \-n
25: means less than
26: .I n
27: and
28: .I n
29: means exactly
30: .IR n .
31: .TP 10n
32: .BR \-name " filename"
33: True if the
34: .I filename
35: argument matches the current file name.
36: Normal
37: Shell
38: argument syntax may be used if escaped (watch out for
39: `[', `?' and `*').
40: .TP
41: .BR \-perm " onum"
42: True if the file permission flags
43: exactly
44: match the
45: octal number
46: .I onum
47: (see
48: .IR chmod (1)).
49: If
50: .I onum
51: is prefixed by a minus sign,
52: more flag bits (017777, see
53: .IR stat (2))
54: become significant and
55: the flags are compared:
56: .IR (flags&onum)==onum .
57: .TP
58: .BR \-type " c"
59: True if the type of the file
60: is
61: .I c,
62: where
63: .I c
64: is
65: .B "b, c, d, f"
66: or
67: .B l
68: for
69: block special file, character special file,
70: directory, plain file, or symbolic link.
71: .TP
72: .BR \-links " n"
73: True if the file has
74: .I n
75: links.
76: .TP
77: .BR \-user " uname"
78: True if the file belongs to the user
79: .I uname
80: (login name or numeric user ID).
81: .TP
82: .BR \-group " gname"
83: True if the file belongs to group
84: .I gname
85: (group name or numeric group ID).
86: .TP
87: .BR \-size " n"
88: True if the file is
89: .I n
90: blocks long (512 bytes per block).
91: .TP
92: .BR \-inum " n"
93: True if the file has inode number
94: .I n.
95: .TP
96: .BR \-atime " n"
97: True if the file has been accessed in
98: .I n
99: days.
100: .TP
101: .BR \-mtime " n"
102: True if the file has been modified in
103: .I n
104: days.
105: .TP
106: .BR \-exec " command"
107: True if the executed command returns
108: a zero value as exit status.
109: The end of the command must be punctuated by an escaped
110: semicolon.
111: A command argument `{}' is replaced by the
112: current pathname.
113: .TP
114: .BR \-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: .BR y .
121: .TP
122: .B \-print
123: Always true;
124: causes the current pathname to be printed.
125: .TP
126: .BR \-newer " file"
127: True if
128: the current file has been modified more recently than the argument
129: .I file.
130: .PP
131: The primaries may be combined using the following operators
132: (in order of decreasing precedence):
133: .TP 4
134: 1)
135: A parenthesized group of primaries and operators
136: (parentheses are special to the Shell and must be escaped).
137: .TP 4
138: 2)
139: The negation of a primary
140: (`!' is the unary
141: .I not
142: operator).
143: .TP 4
144: 3)
145: Concatenation of primaries
146: (the
147: .I and
148: operation
149: is implied by the juxtaposition of two primaries).
150: .TP 4
151: 4)
152: Alternation of primaries
153: .RB "(`" \-o "' is the"
154: .I or
155: operator).
156: .SH EXAMPLE
157: To remove all files named
158: `a.out' or `*.o' that have not been accessed for a week:
159: .IP "" .2i
160: find / \\( \-name a.out \-o \-name '*.o' \\)
161: \-atime +7 \-exec rm {} \\;
162: .SH FILES
163: /etc/passwd
164: .br
165: /etc/group
166: .SH "SEE ALSO"
167: sh(1), test(1), fs(5)
168: .SH BUGS
169: The syntax is painful.
