-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 CONFORMANCE below).  To ignore  a  directory  and
       the  files  under  it,  use  -prune;  see  an example in the description of -path.  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.
-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 section for examples of the use of the -exec option.   The  specified
       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 action; you  should  use  the
       -execdir option instead.

-exec command {} +
       This variant of the -exec action 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 invocations  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.
pattern scanning and processing language
-F  ERE
       Define  the  input  field separator to be the extended regular expression ERE, before any input is
       read; see Regular Expressions .
program
       If no -f option is specified, the first operand to awk shall be the text of the awk  program.  The
       application shall supply the program operand as a single argument to awk. If the text does not end
       in a <newline>, awk shall interpret the text as if it did.

argument
       Either of the following two types of argument can be intermixed:

file
       A pathname of a file that contains the input to be read, which  is  matched  against  the  set  of
       patterns  in  the  program.  If  no file operands are specified, or if a file operand is '-' , the
       standard input shall be used.

assignment
       An operand that begins with an underscore or alphabetic character from the portable character  set
       (see  the  table  in  the  Base  Definitions volume of IEEE Std 1003.1-2001, Section 6.1, Portable
       Character Set), followed by a sequence of underscores, digits, and alphabetics from  the  portable
       character  set,  followed  by the '=' character, shall specify a variable assignment rather than a
       pathname. The characters before the '=' represent the name of an awk variable; if that name is  an
       awk  reserved  word  (see  Grammar ) the behavior is undefined. The characters following the equal
       sign shall be interpreted as if they appeared in the  awk  program  preceded  and  followed  by  a
       double-quote ( ' )' character, as a STRING token (see Grammar ), except that if the last character
       is an unescaped backslash, it shall be interpreted as a literal backslash rather than as the first
       character  of  the  sequence  "\"" . The variable shall be assigned the value of that STRING token
       and, if appropriate, shall be considered a numeric string (see Expressions in awk ), the  variable
       shall  also be assigned its numeric value. Each such variable assignment shall occur just prior to
       the processing of the following file, if any. Thus, an assignment before the first  file  argument
       shall  be  executed  after  the  BEGIN  actions  (if any), while an assignment after the last file
       argument shall occur before the END actions (if any). If there are no file arguments,  assignments
       shall be executed before processing the standard input.
