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.

shell, the standard command language interpreter

-c     Read commands from the command_string operand. Set the value of special parameter 0  (see  Special
       Parameters ) from the value of the command_name operand and the positional parameters ($1, $2, and
       so on) in sequence from the remaining argument operands.  No  commands  shall  be  read  from  the
       standard input.
