find − find files
find pathname-list expression
Find
recursively descends the directory hierarchy for each
pathname in the pathname-list (i.e., one or more
pathnames) seeking files that match a boolean
expression written in the primaries given below. In
the descriptions, the argument n is used as a decimal
integer where +n means more than n, −n
means less than n and n means exactly
n.
−name filename
True if the filename argument matches the current file name. Normal Shell argument syntax may be used if escaped (watch out for ’[’, ’?’ and ’*’).
−perm onum
True if the file permission flags exactly match the octal number onum (see chmod(1)). If onum is prefixed by a minus sign, more flag bits (017777, see stat(2)) become significant and the flags are compared: (flags&onum)==onum.
|
−type c |
True if the type of the file is c, where c is b, c, d or f for block special file, character special file, directory or plain file. | ||
|
−links n |
True if the file has n links. |
−user uname
True if the file belongs to the user uname (login name or numeric user ID).
−group gname
True if the file belongs to group gname (group name or numeric group ID).
|
−size n |
True if the file is n blocks long (512 bytes per block). | ||
|
−inum n |
True if the file has inode number n. | ||
|
−atime n |
True if the file has been accessed in n days. | ||
|
−mtime n |
True if the file has been modified in n days. |
−exec command
True if the executed command returns a zero value as exit status. The end of the command must be punctuated by an escaped semicolon. A command argument ’{}’ is replaced by the current pathname.
−ok command
Like −exec except that the generated command is written on the standard output, then the standard input is read and the command executed only upon response y.
|
|
Always true; causes the current pathname to be printed. |
−newer file
True if the current file has been modified more recently than the argument file.
The primaries may be combined using the following operators (in order of decreasing precedence):
|
1) |
A parenthesized group of primaries and operators (parentheses are special to the Shell and must be escaped). | ||
|
2) |
The negation of a primary (’!’ is the unary not operator). | ||
|
3) |
Concatenation of primaries (the and operation is implied by the juxtaposition of two primaries). | ||
|
4) |
Alternation of primaries (’−o’ is the or operator). |
To remove all files named ’a.out’ or ’*.o’ that have not been accessed for a week:
|
find / \( −name a.out −o −name ’*.o’ \) −atime +7 −exec rm {} \; |
/etc/passwd
/etc/group
sh(1), test(1), filsys(5)
The syntax is painful.
