Well I just wrote my first shell script today and I wanted to share this experience with you all. Its an amazing feeling, jr. programming 101 or something to that effect. I figured i'd share this easy script with you guys, any comments, suggestions or improvements are appreciated and desired.

I used this as my primary guide, I am still going through it, but that and some youtube videos so far gave me what I needed to build this script.


fairly simple, but useful I hope in future studies... >  One thing I wanted to do, not sure if it's possible, but originally, I wanted "scanning..." or something to that effect to be displayed while the command was running, and then "scan complete" at the end. Can that be done without adding too much complexity?

Also, many of the examples I saw used quotation marks around statements that were to be echoed. Based on what I found, quotes are used for variables or something to that effect, can someone explain them to me, and when they should/should not be used?

localhost???  Network is 0, not gateway...  He's scanning a network range.

No worries.  Wasn't trying to embarrass anyone.  Just making sure we kept things straight.

Cheers, ZeroOne!

SephStorm - even before 'prettying it up' with your scanning message, might I suggest figuring out something you'll find more useful -

Work out how to pass in variables to your scripts, such that you can pass in a network address and subnet mask, from a command-line, so you could use it in other networks.  (This type of scripting will come in handy on pentests, when you can 'modularize' things and pass in variable data, for faster automation of scanning activity.)

Using arguments passed from command line is also relatively easy, you should play with this as well  

Example:
echo Hi $1, you like $2 and you also like $3. The script name is $0.

Usage:
./bashscript MaXe 0days knowledge

Output:
Hi MaXe, you like 0days and you also like knowledge. The script name is bashscript.

You can also use more advanced things such as "getopts". But that example I gave you, is very handy when you need a dynamic script quickly  

Nah.  I got confidence in you.  MaXe literally gave you all you need, in order to do it.  It really IS that easy!

If i'm not mistaken, you are talking about variables here right?

like this?

I think I know what MaXe is saying here, instead of the arguments being defined explicitly in the script, I can specify them in my command string and have for instance:


./pingscan.sh 192.168.1.0/24 pingscan

correct?
