nop

nop [ -p? ] [ files ]

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.

The following options are supported:

-p

Produce no output - just check the input for valid DOT.

-?

Print usage information.

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.
