To avoid this scenario use below  steps.

1:First create run.sh file on /home/wildfly-10.1.0.Final/bin/ folder.

nohup ./standalone&

where

• ./standalone : is name of shell script or command name. You can pass argument to command or a shell script.
• & : nohup does not automatically put the command it runs in the background; you must do that explicitly, by ending the command line with an & symbol.
