This is incredible and makes me think a website like this could and should exist, containing an interface to as many unix tools as possible.<p>Yes, one could "RTFM" as one commenter mentioned, but if you're just a casual CLI user, this sort of interface seems incredibly handy. "I know I want to use cURL but I don't know what arguments I need to do X and Y". Use the interface to piece together a whole command, with nice instructions for every little flag and argument available so you know what you're doing.<p>It's kind of like those visual regex builders. They're amazing!
It would be more didactically useful to not use a lower-uppercase font for the resulting options, right now it causes a lot of confusion: should you use `-I eth0` or `-i eth0`?<p>(I had to look it up, the lower case variant is the correct one.)
Cool stuff,
I would personally enforce the "count" packet to 100 or 1000 by default. This way, you make sure that no one crashes this powerful device. If someone knows what is doing, then he could just disable it.<p>Sniffing at +10Gbps can be tricky sometimes.
So my first thought was this is really cool, and it is. However I realized I would never use it as if I need tcpdump, I am on a CLI and I am just going to type man for things I need to look up.
