When working within the Linux terminal and issuing a command to launch an application, the terminal will continue to run that application and it may seem the need to spawn a new terminal window. However, with using the command shortcut to foreground a process (ctrl + z), this will take the current application within terminal and place it as a background process:
root@kali:~# maltego

When the background a process command shortcut is issued, the current process is backgrounded and awaits for further input from the user. You will now notice the application may seem unresponsive. To resume the process, you will need to bring the process to the foreground using the fg
root@kali:~# fg 1
maltego
To obtain the number ID for the backgrounded process to restore as a foreground process, you can issue the jobs command:
root@kali:~# jobs
[1]+ Stopped maltego
