[opensuse] Starting apps automatically in console session - SOLVED
Hi all, A while back I asked how to start console apps automatically in a certain konsole session. I just want share the little script I wrote last night: it launches the atop utility in an existing session named "Atop". Might be the general idea behind is useful for somebody out there. That's why I've put a few more comments in it ...

That looks handy. I can see using it. You might consider generalizing it a bit. E.g., if a script matching the session name can be found in a particular directory, say $HOME/session-startup/, then that script is launched in the matching session. Then the script need not be modified to accommodate changes in the complement of pre-assigned sessions you want to handle.

Assuming an invocation of this script is to be placed in $HOME/.bash_profile, you might want to gracefully handle the case where the shell is running outside of KDE. That includes on virtual consoles, when connecting remotely via ssh and possible when using screen. I don't know if Gnome uses dcop or something else, so it might fail there and under different desktops and window managers as well. In short, be prepared for dcop to fail and do nothing (probably silently) in that case.
Rgds, Stephan.

God morning, - how would one be able to detect if the script is being started outside of KDE? Can anyone come up with a short hint ? - thank you! -- ------------------------------------------------------------------------- Med venlig hilsen/Best regards Verner Kjærsgaard Novell Certified Linux Professional 10035701 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hi Verner Maybe your script could check with env? Using konsole I get peter@talshiar:~> env | grep KDE KDE_MULTIHEAD=false KDE_NO_IPV6=1 KDE_FULL_SESSION=true KDE_SESSION_UID=1000 peter@talshiar:~> In a text console, nothing shows up.

Hi all, Thanks for the feedback, especially Randall's hints for generalization. Also, I've added already a few lines of code to check if dcop is installed and executable. Verner Kjærsgaard wrote:

God morning,
- how would one be able to detect if the script is being started outside of KDE? Can anyone come up with a short hint ? - thank you! I've made sure that the script is started via the $HOME/.kde/Autostart folder, not in $HOME/.bash_profile or another shell rc file. This makes sure that it is launched only in KDE and that it is launched only once, not with every new shell.

Absolutely! I personally have great difficulty without seeing examples. -ED- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

So now that you've made changes, Patrick's request comes up again (make the script available!). Perhaps you could place the script somewhere accessible to all in its latest form (a server of your own, an entry on the openSUSE Wiki, e.g.). In fact, I think the KDE project itself would allow you to publish it as contributed software.
