interactive bash shell program

I was wondering if some one could point me in the right direction as to how I would program a bash shell program that would be interactive.. like say.. scapy or metasploit (the msfconsole).

Any ideas?? Thanks for any input. :)

What do you want your script to do exactly?

Oh, and it's unibomber. Uni is a prefix meaning "one" or "single".

What I'm referring to is say when you enter ./msfconsole .. you are then brought up to the metasploit interactive console.

I was just wondering if this is possible to do with the bash shell, for like making simple text games or what have you.

Yup, it's possible. Basically, you just need to do this:

read CMD;
echo $CMD;```


Also, here's a tutorial on bash scripting: http://www.linuxconfig.org/Bash_scripting_Tutorial

Bourne-again shell shell?

Edit: btw, you don't need to use Bash in order to create fucking console applications/scripts. You can give command-line parameters to virtually every language.

Well I was thinking of making a text based game that would look something like this:

root@somebox~$ ./game.sh (to run the game)

#################WelcomeToTheGame##################

TheGame>help

createcharacter …………………… create your character etc.. help ………………………………… list help etc etc

TheGame>

Where if you're in the interactive mode you no longer see "root@somebox~$ " because the game is taking control of the full console screen.

I imagine I might need to use stty. Any other ideas?

@Spyware: I'm choosing bash because it's what I'm most familiar with.
