				    find . -fsonly hfs -print
				    find . -print -fstype hfs -only
				    find . -print ! -fstype hfs -prune

			       Note, however, that -only is useless if the
			       -depth option has also been given.  Always
			       true.

      ( expression )	       True if the parenthesized expression is true.
			       The spaces are required.	 Parentheses are
			       special to the shell and must be escaped, as
			       in \( and \).

      Primaries can be combined by using the following operators (in order
      of decreasing precedence):

      ! expression		    Logical NOT operator.  True if
				    expression is not true.

      expression [-a] expression    Logical AND operator.  True if both of
				    the expressions are true.

      expression -o expression	    Logical OR operator.  True if either or
				    both of the expressions are true.

      If expression is omitted, or if none of -print, -ok, -exec, -cpio, or
      -ncpio is specified, -print is assumed.  The -user, -group, and -newer
      primaries each evaluate their respective arguments once.

    HFS Access Control Lists
      The -acl primary enables the user to search for HFS access control
      list entries. It is true if the file's access control list matches an
      access control list pattern or contains optional access control list
      entries (see acl(5)).  It has three forms:

      -acl aclpatt	       Match all files whose access control list
			       includes all (zero or more) pattern entries
			       specified by the aclpatt pattern.

      -acl =aclpatt	       Match a file only if its access control list
			       includes all (zero or more) pattern entries
			       specified by the aclpatt pattern, and every
			       entry in its access control list is matched
			       by at least one pattern entry specified in
			       the aclpatt pattern.

      -acl opt		       Match all files containing optional access
			       control list entries.

      The aclpatt string can be given as an operator or short form pattern;
      see acl(5).

      By default, -acl is true for files whose access control lists include
      all the (zero or more) access control list patterns in aclpatt.  A
      file's access control list can also contain unmatched entries.

      If aclpatt begins with =, the remainder of the string must match all
      entries in a file's access control list.

      The aclpatt string (by default, or the part following =) can be either
      an access control list or an access control list pattern.	 However, if
      it is an access control list, aclpatt must include at least the three
      base entries ((user.%, mode), (%.group, mode), and (%.%, mode)).

      As a special case, if aclpatt is the word opt, the primary is true for
      files with access control list entries.

    JFS Access Control Lists
      The -aclv primary enables the user to search for JFS access control
      list entries. It is true if the file's access control list matches an
      access control list pattern or contains optional access control list
      entries (see aclv(5)).  It has three forms:

      -aclv aclpatt	       Match all files whose access control list
			       includes all (zero or more) pattern entries
			       specified by the aclpatt pattern.

      -aclv =aclpatt	       Match a file only if its access control list
			       includes all (zero or more) pattern entries
			       specified by the aclpatt pattern, and every
			       entry in its access control list is matched
			       by at least one pattern entry specified in
			       the aclpatt pattern.

      -aclv opt		       Match all files containing optional access
			       control list entries.

      By default, -aclv is true for files whose access control lists include
      all the (zero or more) access control list patterns in aclpatt.  A
      file's access control list can also contain unmatched entries.

      If aclpatt begins with =, the remainder of the string must match all
      entries in a file's access control list.

      An aclpatt consists of a type field, an ID field, and a mode field,
      separated by colons.  Multiple comma-separated aclpatts may be
      specified.

      The type field is one of user, group, class, other or *, optionally
      preceded by default:.  user, group, class, other and default can be
      abbreviated to u, g, c, o and d, respectively.  A type field of *
      matches any of the above types.

      The ID field is either a numeric user or group ID, a user or group ID
      string from /etc/passwd or /etc/group respectively, or *, which
      matches any ID.

      The mode field consists of a string of three characters.	The first
      character is either r, indicating that read permission is granted; -,
      indicating that read permission is denied; or ?, which matches either
      state of read permission.	 The second character is either w, -, or ?,
      similarly indicating the state of write permission; and the third
      character is either x, -, or ?, indicating the state of execute
      permission.

      As a special case, if aclpatt is the word opt, the primary is true for
      files with optional access control list entries.

 EXTERNAL INFLUENCES
    Environment Variables
      If an internationalization variable is not specified or is null, it
      defaults to the value of LANG.

      If LANG is not specified or is null, it defaults to C (see lang(5)).

      If LC_ALL is set to a nonempty string value, it overrides the values
      of all the other internationalization variables.

 find(1)							     find(1)




      If any internationalization variable contains an invalid setting, all
      internationalization variables default to C (see environ(5)).

      LC_CTYPE determines the interpretation of text as single and/or
      multibyte characters, the classification of characters as printable,
      and the characters matched by character class expressions in regular
      expressions.

      LC_MESSAGES determines the locale that should be used to affect the
      format and contents of diagnostic messages written to standard error
      and informative messages written to standard output.

      NLSPATH determines the location of message catalogues for the
      processing of LC_MESSAGES.

    International Code Set Support
      Single- and multibyte character code sets are supported.

 EXAMPLES
      Search the two directories /example and /new/example for files
      containing the string Where are you and print the names of the files:

	   find /example /new/example -exec grep -l 'Where are you' {} \;

      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 {} \;

	   Note that the spaces delimiting the escaped parentheses are
	   required.

      Print the names of all files on this machine.  Avoid walking nfs
      directories while still printing the nfs mount points:

	   find / -fsonly hfs -print

      Match only local files, and do not examine the contents of any
      directory found to be remotely mounted:

	   find / ! -local -prune -o -size +50 -print

      This only works correctly if there are no local file systems mounted
      on top of remote directories. This example will print all local files
      on the system larger than 50 blocks, without wasting time accessing
      remote files.

      To get the same effect, but to check for files in local file systems
      mounted on remote directories, use:





 Hewlett-Packard Company	    - 9 -   HP-UX Release 11i: November 2000






 find(1)							     find(1)




	   find / -local -size +50 -print

      Copy the entire file system to a disk mounted on /Disk, avoiding the
      recursive copy problem.  Both commands are equivalent (note the use of
      -path instead of -name):

	   cd /; find . ! -path ./Disk -only -print | cpio -pdxm /Disk
	   cd /; find . -path ./Disk -prune -o -print | cpio -pdxm /Disk

      Copy the root disk to a disk mounted on /Disk, skipping all mounted
      file systems below /.  Note that -xdev does not cause / to be skipped,
      even though it is a mount point.	This is because / is the starting
      point and -xdev only affects entries below starting points.

	   cd /;  find . -xdev -print | cpio -pdm /Disk

      Change permissions on all regular files in a directory subtree to mode
      444, and permissions on all directories to 555:

	   find pathname -type f -print | xargs chmod 444
	   find pathname -type d -print | xargs chmod 555

	   Note that output from find was piped to xargs(1) instead of using
	   the -exec primary.  This is because when a large number of files
	   or directories is to be processed by a single command, the -exec
	   primary spawns a separate process for each file or directory,
	   whereas xargs collects file names or directory names into
	   multiple arguments to a single chmod command, resulting in fewer
	   processes and greater system efficiency. The + delimiter for the
	   -exec primary can be used to achieve the same efficiency.

    Access Control List Examples
      Find all files not owned by user karl that have access control lists
      with at least one entry associated with karl, and one entry for no
      specific user in group bin with the read bit on and the write bit off:

	   find	 /  ! -user karl -acl 'karl.*, %.bin+r-w' -print

      Find all files that have a read bit set in any access control list
      entry:

	   find	 /  -acl '*.*+r' -print

      Find all files that have the write bit unset and execute bit set in
      every access control list entry:

	   find	 /  -acl '=*.*-w+x' -print

      Find all files that have optional access control list entries:

	   find	 /  -acl opt -print

 DEPENDENCIES
    NFS
      The -acl primary is always false for NFS files.

 WARNINGS
      Because of interoperability goals, cpio does not support archiving
      files larger than 2GB or files that have user/group IDs larger than
      60,000 (60K).  Files with user/group IDs greater than 60K are archived
      and restored under the user/group ID of the current process.
