find(1) DG/UX 4.30 find(1)
NAME
find - find files
SYNOPSIS
find path-name-list expression
DESCRIPTION
Find recursively descends the directory hierarchy for each
path name in the path-name-list (i.e., one or more path
names) seeking files that match a boolean expression written
in the primaries given below. In the descriptions, the
argument n is a decimal integer where +n means more than n,
-n means less than n and n means exactly n.
Arguments that are normally numeric are terminated by the
first non-numeric character in the argument, and the
remaining characters are ignored. If the argument's first
character is not numeric, the argument is considered
equivalent to 0.
-name file True if file 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, only
the bits set in onum are compared to
permission flags. If the bits and the
permission flags match, then -perm evaluates
to true.
-type c True if the type of the file is c, where c
is
b block special file
c character special file
d directory
p fifo (named pipe)
f plain file
l symbolic link file
s socket files in the AF _UNIX domain
-links n True if the file has n links.
-user uname True if the file belongs to the user uname.

If uname is numeric and does not appear as a
login name in the /etc/passwd file, it is
taken as a user ID.
-group gname True if the file belongs to the group gname.
If gname is numeric and does not appear in
the /etc/group file, it is taken as a group
ID.
-size n[c] True if the file is n blocks long (512 bytes
per block). If n is followed by a c, the
size is in characters.
-atime n True if the file was accessed n days ago.
The access time of directories in path-
name-list is changed by find itself.
-mtime n True if the file was modified n days ago.
-ctime n True if the file changed n days ago.
-exec cmd; True if the executed cmd returns a zero
value as exit status. The end of cmd is
indicated by the semicolon. To keep the
shell from interpreting this semicolon as
the end of your command line, you should
precede it with a backslash (see example).
A command argument {} is replaced by the
current path name.
-ok cmd Like -exec , but the generated command line
is printed with a question mark first, and
is executed only if the user responds by
typing y.
-print Always true; prints the current pathname.
-cpio device Always true; write the current file on
device in cpio(4) format (5120-byte
records).
-newer file True if the current file has been modified
more recently than the argument file.
-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. This can be useful when
find is used with cpio(1) to transfer files
that are contained in directories without
write permission.

-mount Always true; restricts the search to the
file system containing the pathname in the
pathname list.
-local True if the file physically resides on the
local system.
( expression ) True if the expression is true (parentheses
are special to the shell and must be
escaped).
You can combine the primaries using the following operators
(in order of decreasing precedence):
1) The negation of a primary (! is the unary not
operator).
2) Concatenation of primaries (the and operation is implied
by the juxtaposition of two primaries).
3) Alternation of primaries (-o is the or operator).
Only those primaries necessary to establish whether the
expression is true or false are evaluated. Thus, for an
expression concatenating two primaries, the second primary
is evaluated only if the first primary is true. For an
expression alternating two primaries, the second primary is
evoked only if the first primary is true.
EXAMPLES
$ find . -perm 777 -print
./a.out
./ed_script
./shell_script
The above example searches the working directory and all
directories below the working directory for files with read,
write, and execute permission for owner, group, and others.
$ find . -print -perm 0777 -exec rm {} \;
The name of every file below `.' is printed. Those files
whose permissions are 0777 are deleted. Note the backslash
that precedes the semicolon terminating the rm command.
$ find . -perm 0777 -o -print
The name of each file whose permissions are not 0777 is
printed.
$ find . -name a.out -print

./a.out
The above example searches the working directory and all
directories below it for a specific file.
$ find / -name passwd -print
/bin/passwd
/etc/passwd
/usr/etc/yp/src/passwd
The above example searches for the passwd file starting from
the root directory. In this case, three different passwd
files were found in different directories.
FILES
/etc/passwd, /etc/group
