A small utility to convert Unix lsof output to a graph showing FIFO and UNIX interprocess communication.

Generate graph:

sudo lsof -n -F | ./lsofgraph | dot -Tjpg > /tmp/a.jpg

or add unflatten to the chain for a better layout:

sudo lsof -n -F | ./lsofgraph | unflatten -l 1 -c 6 | dot -T jpg > /tmp/a.jpg

It seems that Lua was an unfortunate choice, since people keep sending me links to ports in other languages. If you also hate Lua, raise your hand and check the Python port at https://github.com/akme/lsofgraph-python or the Perl port at https://github.com/tehmoth/lsofgraph.
