-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.
-L max-lines
      Use at most max-lines nonblank input lines per command
      line.  Trailing blanks cause an input line to be logically
      continued on the next input line.  Implies -x.

-x, --exit
      Exit if the size (see the -s option) is exceeded.
