Probably should prefer a #!/usr/bin/env lua

$ sudo lsof -n -F | ./lsofgraph

$ lsof -v

Hey, nice job with script, i made python version of it, could you add link to lsofgraph-python?

~/D/lsofgraph ❯❯❯ sudo lsof | ./lsofgraph
digraph G {
        rankdir = LR;
        node [ shape=box, style="rounded,filled" width=0, height=0, fontname=Helvetica, fontsize=10];
        edge [ fontname=Helvetica, fontsize=10];
lua: ./lsofgraph:54: bad argument #2 to 'format' (number expected, got string)
stack traceback:
        [C]: in function 'format'
        ./lsofgraph:54: in function 'printf'
        ./lsofgraph:169: in main chunk
        [C]: in ?

similar output when using -n -F etc. (hacker news brought me here)

Hi,
thanks for this tool I love it on amd86 where lsof is a standalone command. It seems this will not work when lsof is part of busybox because the -F option output will look like:
