# This shell script will stop the 'Multi Relay Chat' python script. It is intended to be called #
|
||
|
|
# via a forked systemd .service file. The script will check that mrc_client.py is running then #
|
||
|
|
# will stop it via SIGTERM. If it can't be stopped gracefully within 30 seconds, it will be #
|
||
|
|
# forcefully stopped. The script will exit with an appropriate error code to indicate whether it #
|
||
|
|
# was successful or not. This script is indended to work only with Debian, Ubuntu, Raspbian and #
|
||
|
|
# other debian based distributions. #
