How to handle multiple parameters from a user's selection in a checklist menu?

Question

I'm creating script that runs commands based on information from a checklist dialog:

dialog --checklist "Choose what you want to install:" 0 0 0  1 mysql on 2 java on  3 git off 2> tempfile

I have the correct data in tempfile (1 2), but I don't know how to use this data in future in my script.

No, that question about **inbox** dialog, but I asked about **chesklist** dialog. **Inbox** returns one parameter, but i want to handle few parameters, which checked in **checkbox** — Valentyn Hruzytskyi, Oct 19 '18 at 11:14

You can use --output-fd 1 to send output to stdout and then capture it as normal.

answer=$(dialog --checklist "Choose what you want to install:" 0 0 0  1 mysql on 2 java on  3 git off --output-fd 1)
