UNIX for Dummies Questions & Answers

       -name pattern
	      Base  of	file  name  (the  path	with  the  leading directories
	      removed) matches	shell  pattern	pattern.   The	metacharacters
	      (`*',  `?',  and `[]') match a `.' at the start of the base name
	      (this is a change in findutils-4.2.2; see section STANDARDS CON-
	      FORMANCE	below).  To ignore a directory and the files under it,
	      use -prune; see an example in  the  description  of  -wholename.
	      Braces  are  not	recognised  as being special, despite the fact
	      that some shells including Bash  imbue  braces  with  a  special
	      meaning  in  shell patterns.  The filename matching is performed
	      with the use of the fnmatch(3) library function.	 Don't	forget
	      to  enclose  the	pattern  in quotes in order to protect it from
	      expansion by the shell.
       -size n[cwbkMG]
	      File uses n units of space.  The following suffixes can be used:

	      `b'    for 512-byte blocks (this is the default if no suffix  is
		     used)

	      `c'    for bytes

	      `w'    for two-byte words

	      `k'    for Kilobytes (units of 1024 bytes)

	      `M'    for Megabytes (units of 1048576 bytes)

	      `G'    for Gigabytes (units of 1073741824 bytes)

	      The  size  does  not  count  indirect  blocks, but it does count
	      blocks in sparse files that are not actually allocated.  Bear in
	      mind  that the `%k' and `%b' format specifiers of -printf handle
	      sparse  files  differently.   The  `b'  suffix  always   denotes
	      512-byte	blocks and never 1 Kilobyte blocks, which is different
	      to the behaviour of -ls.
       -exec command ;
	      Execute command; true if 0 status is  returned.	All  following
	      arguments to find are taken to be arguments to the command until
	      an argument consisting of `;' is encountered.  The  string  `{}'
	      is  replaced by the current file name being processed everywhere
	      it occurs in the arguments to the command, not just in arguments
	      where  it  is alone, as in some versions of find.  Both of these
	      constructions might need to be escaped (with a `\') or quoted to
	      protect them from expansion by the shell.  See the EXAMPLES sec-
	      tion for examples of the use of the `-exec' option.  The	speci-
	      fied  command is run once for each matched file.	The command is
	      executed in the  starting  directory.    There  are  unavoidable
	      security	problems  surrounding  use  of	the  -exec option; you
	      should use the -execdir option instead.

       -exec command {} +
	      This variant of the -exec option runs the specified  command  on
	      the  selected  files, but the command line is built by appending
	      each selected file name at the end; the total number of  invoca-
	      tions  of  the  command  will  be  much  less than the number of
	      matched files.  The command line is built in much the  same  way
	      that  xargs builds its command lines.  Only one instance of '{}'
	      is allowed within the command.  The command is executed  in  the
	      starting directory.

find /path/to/search -name '*.mov' -size +800M -exec rm {} \;

find dir_name -name "*.mov" -type f -xdev -size +800m -exec rm -f {} \;
