nop - pretty-print graph file
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.
