You can run a command or script after
apt-get by using the && operator. For example, if you want to install a package and then run a script, you can run the following command:sudo apt-get install <package-name> && <path-to-script>
This will install the package, and if the installation is successful, it will run the script. If the installation fails, the script will not run.
You can also run a command in the background while apt-get continues to run by appending an ampersand & symbol to the command:
sudo apt-get install <package-name> ; <command> &
Note that the semicolon ; is used to separate the two commands, and the ampersand & is used to run the second command in the background.
