find
find(1) General Commands Manual find(1)Name
find - find files
Syntax
find pathname-list expression
Description
The command recursively descends the directory hierarchy for each pathname in the pathname-list (that is, 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 inte-
ger where +n means more than n, -n means less than n , and n means exactly n.
Options-atime n Tests true if the file has been accessed in n days.
-cpio output Writes current file on output in the format (5120-byte records) specified in the reference page. The output can be either a
file or tape device. If output is a tape device the B key must be used to read data from the tape.
-ctime n Tests true if the file has been changed in n days.
-depth Always true; causes descent of the directory hierarchy to be done so that all entries in a directory are acted on before the
directory itself (that is, postorder instead of preorder). This can be useful when is used with to transfer files that are
contained in directories without write permission.
-exec command Tests true if specified command returns a 0 on exit. The end of the command must be punctuated by an escaped semicolon. A
command argument `{}' is replaced by the current pathname.
-group gname Tests true if group ID matches specified group name.
-inum n Tests true if the file has inode number n.
-links n Tests true if the file has n links.
-mount Tests true if the current file is on the same file system as the current starting pathname.
-mtime n Tests true if the file has been modified in n days.
-name filename Tests true if the filename argument matches the current file name. Normal Shell argument syntax may be used if escaped
(watch out for `[', `?' and `*').
-newer file Tests true if the current file has been modified more recently than the argument file.
-ok command Executes specified command on standard output, then standard input is read and command executed only upon response y.
-perm onum Tests true if file has specified octal number. For further information, see If onum is prefixed by a minus sign, more flag
bits (017777) become significant and the flags are compared: (flags&onum)==onum. For further information, see
-print Prints current pathname.
-size n Tests true if the file is n blocks long (512 bytes per block).
-type c Tests true if file is c type ( c = b, block special file: c, character special file: d, directory: f, plain file: l, sym-
bolic link: p, type port: s, type socket).
-user uname Tests true if file owner is login name or numeric user ID.
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).
Examples
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 {} ;
To find all files on the root file system type:
find / -mount -print
To write all the files on the root file system to tape:
find / -mount -print -cpio /dev/rmt?h
cpio -iBvt < /dev/rmt?h
To find all the mount points on the root file system type:
find / ! -mount -print
