ABSTRACT:
An information handling system (IHS) employs operating system software to manage IHS resources. The operating system software manages software application programs as processes executing within the IHS. The processes run in foreground and background mode within the IHS. Processes running in foreground mode are subject to hang-up events with negative process output results, such as output data loss. In one embodiment, the operating system software supports a “no hang-up now” command for use with processes running in foreground mode. The “no hang-up now” command provides system users the ability to hang-up or log-out of an IHS terminal without negative effects on the current foreground process. A user may invoke the “no hang-up now” command after execution of the foreground process is already underway. The no hang-up command moves the foreground application to the background for continued execution. A signal handler program prevents termination of the background process until the process completes.
