PROBLEM:



I have a program written in bash that does a lot of stuff like install new software on the system.



One of the programs it installs has an extravagant message appear where you get some info about usage and the configuration file and what it does if you don't edit the config file.



And then waits for user input.



This message is a dialog kind of message in a gui:



enter image description here



The program that display's this message is portsentry and the system is Debian Stretch.



QUESTION:




How can I suppress this message so there is no communication between my program and the user?







shell-script debian scripting software-installation messaging

It is a team of 2: just I and my supervisor. Diurnally, I am posed with a "bug of the day" to get out of this C++ code. My supervisor generally gives me about 15-30 minutes to solve it and then accosts me about whether or not the task is completed and then rinses and repeats this until the end of the day.

This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of
