Say I run an app from a terminal, but in some cases I want to close the terminal but hope the app keeps running. Is there anyway to do so in Linux?I just found that when calling an app via exec APP, either would be closed if the other was closed. 
Is there a way to keep an app running after closing the terminal that calls it?
terminal
Start the application with:nohup your_application &It will continue running after you exit the terminal. If you use tmux or screen and start the your_application from inside that, you can reattach to the output after closing the terminal and opening another.
