Ubuntu: Kill all instances of a service



Question:

I managed to create a systemd service script, which enables my application to run in the background...
This systemdscript used %i in order to start specific instances of this service.
I'm searching for a way to stop all instances of my script.
sudo service servicename@* stop isn't working...
ExecStart runs a script which runs a java application

Any help is appreciated


Solution:1

The command you are looking for is:

sudo killall nameofservice  

You can use tab to autocomplete.


Solution:2

You better use

sudo killall -9 nameofservice  

Of course you need to know the name of the service which is not necessarily equal to its init.d script name.

The parameter -9 of the killall command is explained in the manual page

man 7 signal  

Just enter it at the command line to get:

First the signals described in the original POSIX.1-1990 standard.

Solution:3

Thanks for all your suggestions, but I found an answer here: https://serverfault.com/a/797926
The problem was, that my asterisk was escaped by bash...
When using sudo service 'servicename@*' stop everything works as expected
