запускать и останавливать программы системных демонов (start and stop system daemon programs)
Описание (Description)
start-stop-daemon is used to control the creation and termination
of system-level processes. Using one of the matching options,
start-stop-daemon can be configured to find existing instances of
a running process.
Note: unless --pid or --pidfile are specified, start-stop-daemon
behaves similar to killall(1). start-stop-daemon will scan the
process table looking for any processes which match the process
name, parent pid, uid, and/or gid (if specified). Any matching
process will prevent --start from starting the daemon. All
matching processes will be sent the TERM signal (or the one
specified via --signal or --retry) if --stop is specified. For
daemons which have long-lived children which need to live through
a --stop, you must specify a pidfile.
