No this won't work. Systemd is not a shell. Simply write a bash script where you do all your stuff and then put that as the ExecStart line. > 2. How can I run multiple instances of an executable with different > arguments? > > You might be able to use template units. Name your service name@.service and then you can start it as name@arg.service and reference arg via the %i and %I (large i) specifiers in the ExecStart line. http://www.freedesktop.org/software/systemd/man/systemd.unit.html has further information. > 3. How can I use user-defined signals in the service scripts? > Does http://www.freedesktop.org/software/systemd/man/systemd.kill.html help you? > Please give me a few clues. > > Best regards, > --Chinmay > > Mirco
