Linux – systemd – Giving the service multiple arguments

linuxsystemd

Is it possible to give my systemd service more than one argument?

I'd like to execute a program with multiple arguments which have to be decided by the final user.

E.g: ./program arg1 arg2

To start it a single argument app I'd need something like systemctl start arg1@program, where in the service definition I have ExecStart = /usr/bin/program ℅i.

Thanks!

Yes you can! Define them in a file somewhere and add them to EnvironmentFile in your systemd Service. For example, say the contents of /etc/.progconf are:

ARG1=-o
ARG2=--verbose

And your .service file:

EnvironmentFile=/etc/.progconf
ExecStart = /usr/bin/prog $ARG1 $ARG2

You can write to that file if you need to change them on the go. A service shouldn't change its options very often, maybe consider autostarting or cron if you need to achieve that.
