	Because that's xargs' job.

DESCRIPTION
      The xargs utility reads space, tab, newline and end-of-file 
delimited
      arguments from the standard input and executes the specified 
utility with
      them as arguments.

      The utility and any arguments specified on the command line are 
given to
      the utility upon each invocation, followed by some number of the 
argu-
      ments read from standard input.  The utility is repeatedly 
executed until
      standard input is exhausted.
