In my line of work I need to run nmap, nikto, dig, and bunch of other tools against several targets almost on daily basis. Because I am lazy I created a tool to do that for me. It's called lazyfoot, where foot stands for footprinting. It's wirtten in Ruby, isn't fancy and only around 300 lines of code long.

So far the main functions are:
nmap
nikto
httrack
whois
dig

It also looks for some files after in the sites httrack got, and does chown & chgrp because it has to be run as root. I need to figure out how to properly do version numbering because right now it's a mess.

This little thing is is still under development but already saved me a bunch of time. Maybe you'll find it useful too.

EDIT 2:

I guess I should give some usage examples....
