looking for some help with this,
i have a desktop file that i need to copy a file, and then kill a process,
looks like this so far:

Exec=osso-xterm 'sudo cp -r /home/user/MyDocs/rtcom-messaging-ui.launch /usr/bin/'
Exec=osso-xterm 'sudo killall rtcom-messaging-ui'

but the second part is not doing anything

also tried it in one single command like this:

Exec=osso-xterm 'sudo cp -r /home/user/MyDocs/rtcom-messaging-ui.launch /usr/bin/ killall rtcom-messaging-ui'

but still the killall part does nothing
both commands work if i enter them seperately in xterm,
but again, i need all this in a desktop file so i can run it with the click of a button,
can any of you clever souls help!
