nohup
Destructive
Execute commands immune to SIGHUP, enabling long-running background tasks to persist after terminal exit. Captures output to a file.
Instructions
Run a command immune to SIGHUP (hangup signals), ideal for long-running background tasks. Executes the given command and captures stdout/stderr. Requires --allow_nohup confirmation for safety. Use to run tasks that should survive terminal closure. Not for CPU priority adjustment — use 'nice'. Not for time-bounded execution — use 'timeout'. See also 'nice', 'timeout'.
