              NUM bytes of each file

       -n, --lines=[-]NUM
              print the first NUM lines instead of the first 10; with the leading '-', print all but
              the last NUM lines of each file

       -q, --quiet, --silent
              never print headers giving file names

       -v, --verbose
              always print headers giving file names

       -z, --zero-terminated
