RE: Nmap & Bash Auto-Completion (was: Am I Missing Something?)

[Daniel Miller <bonsaiviking () gmail com>]

Here's a bash-completion script for nmap that covers all the options
in the 5.00 release. There are some preference things that could be
changed, such as which options to tab-complete by default. I'm sure
there's a better way to do the comma-separated list of script
categories and names, but this works. Hope this helps!
