nop - pretty-print graph file

nop  reads a stream of graphs and prints each in pretty-printed (canonical) format on stdout. If no files
       are given, it reads from stdin.

       If any errors occurred while processing any input, such as a file not found or a file containing  illegal
       DOT, a non-zero exit value is returned. Otherwise, zero is returned.
