build and execute command lines from standard input

--max-args=max-args
-n max-args
       Use at most max-args arguments per command line.  Fewer than max-args arguments will  be  used  if
       the  size (see the -s option) is exceeded, unless the -x option is given, in which case xargs will
       exit.

-I replace-str
       Replace occurrences of replace-str in the initial-arguments with names read from  standard  input.
       Also,  unquoted  blanks  do  not  terminate  input  items;  instead  the  separator is the newline
       character.  Implies -x and -L 1.
