Output File Interpreter (grep-able)

["Livio Zanol Puppim" <livio.zanol.puppim () gmail com>]

Hi,

I want to know where can I find a guide on how to interprete the Greppable
format in shell script without defined options in nmap scan.

Like this:
I have built a simple frontend for nmap where users choose the method(s) of
scanning, and the command it self is passed to a CGI page (based on shell
script) where the scan is made. I need to be able to analyse the output from
the scanning and return it in HTML format displaying all open ports from the
scan separated by the hosts IPs. It can't be in PERL, and it can't use any
of the "non native" shell commands like "*xmllist*" or something like that.
It must use commands like: *grep*, *awk*, *cat*, *sed*, *if*, *for*, *eval*,
etc...

So let's take an example:
Host: 192.168.0.3 () Ports: 80/open/tcp//http///, 443/open/tcp//https///
Ignored State: filtered
Host: 192.168.0.66 () Ports: 139/open/tcp//netbios-ssn///,
445/open/tcp//microsoft-ds//Microsoft Windows XP microsoft-ds/ (etc..)

--------------------------

How can I make a shell script that will grep the First Host(Line) return to
me the ports (number, state, transport protocol, and service description)
and move to the second line in a way that I can do this kind of stuff?

--------------------------

Anyway, is there a guide on how to do it?

Thanks,

Lívio Zanol
