find

FIND(1) 						      General Commands Manual							   FIND(1)

NAME

       find - find files meeting a given condition

SYNOPSIS

       find directory expression

EXAMPLES

       find /  -name a.out -print
			   # Print all a.out paths

       find /usr/ast ! -newer f -ok rm {} ;
			   # Ask before removing

       find /usr -size +20 -exec mv {} /big ;
			   # move files > 20 blks

       find / -name a.out -o -name '*.o'  -exec rm {};
			   # 2 conds

DESCRIPTION

       Find  descends  the  file tree starting at the given directory checking each file in that directory and its subdirectories against a predi-
       cate.  If the predicate is true, an action is taken.  The predicates may be connected by -a (Boolean and), -o (Boolean or) and !   (Boolean
       negation).  Each predicate is true under the conditions specified below.  The integer n may also be +n to mean any value greater than n, -n
       to mean any value less than n, or just n for exactly n.

	 -name s true if current filename is s (include shell wild cards)
	 -size n true if file size is n blocks
	 -inum n true if the current file's i-node number is n
	 -mtime ntrue if modification time relative to today (in days) is n
	 -links ntrue if the number of links to the file is n
	 -newer ftrue if the file is newer than f
	 -perm n true if the file's permission bits = n (n is in octal)
	 -user u true if the uid = u (a numerical value, not a login name)
	 -group gtrue if the gid = g (a numerical value, not a group name)
	 -type x where x is bcdfug (block, char, dir, regular file, setuid, setgid)
	 -xdev	 do not cross devices to search mounted file systems

       Following the expression can be one of the following, telling what to do when a file is found:

	 -print  print the file name on standard output
	 -exec	 execute a MINIX command, {} stands for the file name
	 -ok	 prompts before executing the command
