how to connect with ssh shell then launch command to use tail ...

Hello,

I made a SSH SHELL connexion to my server.
it works fine.

Now I try to automatically use a command after login and I don't find how to do it.

The command : tail -fn 1000 /xxx/log/yyy/catalina.out

I tried to add my command in Event > After Open



but then I have :

unable to execute the command line [#tail"] with argument [-fn 1000 /xxx/log/yyy/catalina.out

is it possible to automatically use a command after login ?
I don't find where to put it
