| shellguard | |
| Signal forwarding intermediary command executer that translates terminal-generated SIGINT/SIGQUIT (Ctlr+C/Ctrl+/) | |
| into SIGTERM/SIGABRT so that shell-backgrounded procesess don't stay running in the background when | |

| Shell scripts don't kill their child processes and instead rely on process-group-wide signals |
