Bash Script Help

[dclardy]

I am updating my script that automatically installs ISPConfig 3 on Debian 6. I am asking the user some questions, and I need those options to be saved so that I can use that to pick the correct installation procedure. I have it all setup, but I can't get it to find the correct options that I have given. Do you have any ideas?

My script can be found here.

To what part of the script are you referring?

[dclardy]

In the first part of the script, I ask the user for input. This inputs are saved as variables, and I need them to be used in selected the correct install function.

The last section $installchoices returns exactly what I need it do, but when it comes to the install functions it is not found.

I am trying to figure out what I need to do to get the user inputs to allow me to select the correct install function.

[falko]

Shouldn't you use

installchoices=install_$mail_server$dns_server$quota$jailkit

instead of

$installchoices=install_$mail_server$dns_server$quota$jailkit

?

[dclardy]

That was part of the problem. There were some other things that I needed to iron out as well, but I have them taken care of now. Thanks for the suggestion.

[falko]

So it's working now?

[dclardy]

Yes. It works. That is why I got you to sticky that Install Script for me!
