Such termination also terminates the GUI apps running in background as their parent Bash shell (= internally launched by the kali.exe) has exited. If you append an '&' ( i.e., xfce4-session&), it'll be pushed to background and the kali.exe will be terminated immediately. Please also note that the 'xfce4-session' doesn't have an '&'. Hence the if then ensures executing the following commands ( i.e., export DISPLAY=.) only when the Xfce desktop isn't already running. ' pidof xfce4-session' Linux command returns the process ID of running xfce4-session (Xfce4 Session Manager). If you don't specify either argument, X410 will be in the same mode as the last time it was used. If you want to launch X410 in ' Windowed Apps' mode, you should use the '/wm' command line argument. If X410 is already running in 'Windowed Apps' mode, it'll be shutdown and started again in 'Desktop' mode.

When '/dektop' is passed as a command line argument, X410 is launched in ' Desktop' mode. Kali.exe run 'if then export DISPLAY=127.0.0.1:0.0 xfce4-session pkill '(gpg|ssh)-agent' fi '
