It is not a command.
It is not a shell.
But why not? For starters, we don’t need the script to execute the command. The main reason is to save the script and use it with whatever the user previously wanted, so that it can be run with the same options as the shell. (That’s the same reason we haven’t used a command before.) I have a feeling that this is a bad idea.
This is not a good idea. Shell_NotifyIcon is a part of Shell-Extensions (SELinux). It is a program that enables users to run a command as the user wishes, and then give them a text-based menu to choose from. However, it is disabled by default. The script you are trying to execute does not do anything with SELinux, so it is not going to work.
So that’s why we have to stop and think about your intentions of what you want to do. It’s all part of the process of trying to get the game going with your head.
The first thing you need to do is make sure you have some sort of SELinux context or shell configuration in place.
If you have already installed some SELinux stuff like the SELinux configuration from the SELinux package, you can use the SELinux configuration for your environment. If you are in another SELinux environment, say a development environment, just set the SELinux configuration there. If you are on a non-SELinux environment, you will need to use some sort of shell configuration.
You must set the SELinux configuration to allow for shell context use. The first step is to edit the /etc/selinux/config file. Here you can see all the environment variables, or the SELinux configuration sections, and most importantly, here you can define which shell context you want to be able to use.
