FIND(1) General Commands Manual FIND(1) NAME
find - find files SYNOPSIS
find pathname-list expression DESCRIPTION
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 semi- colon. 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. -print 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). EXAMPLE
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 {} ; FILES

The syntax is painful. FIND(1)

test(1F) FMLI Commands test(1F) NAME
test - condition evaluation command SYNOPSIS
test expression expression DESCRIPTION
test evaluates the expression expression and if its value is true, sets a 0 (TRUE) exit status; otherwise, a non-zero (FALSE) exit status is set; test also sets a non-zero exit status if there are no arguments. When permissions are tested, the effective user ID of the process is used. All operators, flags, and brackets (brackets used as shown in the second SYNOPSIS line) must be separate arguments to test. Normally these items are separated by spaces. USAGE
Primitives The following primitives are used to construct expression: -r filename True if filename exists and is readable. -w filename True if filename exists and is writable. -x filename True if filename exists and is executable. -f filename True if filename exists and is a regular file. -d filename True if filename exists and is a directory. -c filename True if filename exists and is a character special file. -b filename True if filename exists and is a block special file. -p filename True if filename exists and is a named pipe (FIFO). -u filename True if filename exists and its set-user-ID bit is set. -g filename True if filename exists and its set-group-ID bit is set. -k filename True if filename exists and its sticky bit is set. -s filename True if filename exists and has a size greater than 0. -t[fildes] True if the open file whose file descriptor number is fildes (1 by default) is associated with a terminal device. -z s1 True if the length of string s1 is 0. -n s1 True if the length of the string s1 is non-zero. s1 = s2 True if strings s1 and s2 are identical. s1 != s2 True if strings s1 and s2 are not identical. s1 True if s1 is not the null string. n1 -eq n2 True if the integers n1 and n2 are algebraically equal. Any of the comparisons -ne, -gt, -ge, -lt, and -le may be used in place of -eq. Operators These primaries may be combined with the following operators: ! Unary negation operator. -a Binary and operator. -o Binary or operator (-a has higher precedence than -o). `(expression)` Parentheses for grouping. Notice also that parentheses are meaningful to the shell and, therefore, must be quoted. ATTRIBUTES

find(1), sh(1), attributes(5) NOTES
If you test a file you own (the -r , -w , or -x tests), but the permission tested does not have the owner bit set, a non-zero (false) exit status will be returned even though the file may have the group or other bit set for that permission. The correct exit status will be set if you are super-user. The = and != operators have a higher precedence than the -r through -n operators, and = and != always expect arguments; therefore, = and != cannot be used with the -r through -n operators. If more than one argument follows the -r through -n operators, only the first argument is examined; the others are ignored, unless a -a or a -o is the second argument. SunOS 5.11 5 Jul 1990 test(1F)
