Oh, sorry, the "run" command is my /usr/local/bin/run script that picks
a suitable VM. The effect is the same as running the VM executable directly,
so run the VM in whatever manner you like. I am in the habit of installing
my user executables (the VM run scripts in this case) in /usr/local/bin/ so
that they will be in my $PATH.

Here is what a -doit looks like on my PC. It evaluates the doIt argument,
and once the image opens you can see the #FOO has been added to the system

$ run squeak -- -doit "Smalltalk at: #FOO put: #BAR"

Note the ' -- ' before the '-doit'. However you might decide to invoke
the command line, you can put ' -- ' before the arguments and they
should get get passed along to the image.

Note that this hack is doing the evaluations as the very first thing
in the startUp sequence, so if you evaluate something that (for example)
opens an inspector, that inspector is not necessarily going to place
itself properly in the Morphic world. But it does seem to work, and
being able to do something like this before anything else gets screwed
up in the startUp processing might be a handy thing to be able to do.
