The accepted answer is correct but does not specify how to perform a "safe" shutdown of the rtorrent
service with a systemctl
service script.
Most existing answers or scripts "kill" either the screen session or the rtorrent
process itself. In doing so, they send a SIGINT (2)
or SIGQUIT (3)
signal which stops/kills the rtorrent
process. The drawback is that typically the lock-file of rtorrent
is not deleted because rtorrent
was not shut down properly. Consequently, the next start of rtorrent
would fail because of the persistent lock file.
Taking a look at the source code of rtorrent
shows that it expects a SIGTERM (15)
. Hence, considering a systemctl
service script the stop command could look like:
ExecStop=/usr/bin/kill -s 15 \`pidof rtorrent`
If pidof
is not available you can also use something like:
ps -A | grep "rtorrent" | awk '{print $1}'
ps
list the current processesgrep
extracts the rtorrent process particularsawk
selects the pid and displays it to stdout
In case you need to wait until shutdown is complete, you can use killall -w
. Note that:
killall
may wait forever if the signal was ignored, had no effect, or if the process stays in zombie state (source:man killall
).
