     find - find files

     find pathname expression

     Find recursively descends the directory hierarchy from path-
     name 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(I)).
                     If onum is prefixed by a minus sign, more
                     flag bits (017777, see stat(II)) become sig-
                     nificant and the flags are compared:

     -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

     -links n        True if the file has n links.

     -user uname     True if the file belongs to the user uname.

     -group gname    As it is for -user so shall it be for -group

     -size n         True if the file is n blocks long (512 bytes
                     per block).

     -atime n        True if the file has been accessed in n

     -mtime n        True if the file has been modified in n

     -exec command   True if the executed command returns exit
                     status zero (most commands do).  The end of
                     the command is punctuated by an escaped
                     semicolon.  A command argument `{}' is
                     replaced by the current pathname.


     -ok command     Like -exec except that the generated command
                     line is printed with a question mark first,
                     and is executed only if the user responds y.

     -print          Always true; causes the current pathname to
                     be printed.

     The primaries may be combined with these operators (ordered
     by precedence):

     !               prefix not

     -a              infix and, second operand evaluated only if
                     first is true

     -o              infix or, second operand evaluated only if
                     first is false

     ( expression )  parentheses for grouping.  (Must be

     To remove files named `a.out' and `*.o' not accessed for a

          find / "(" -name a.out -o -name "*.o" ")" -a -atime +7
          -a -exec rm {} ";"


     sh (I), if(I), file system (V)

     There is no way to check device type.
     Syntax should be reconciled with if.
