Regarding command line arguments available to the image, see
#getSystemAttribute:
Squeak has #argumentAt: for getting command line options passed to the image.
This is no longer present in Pharo, but the implementation is just this:
argumentAt: i
"Answer the i-th argument of the command line, or nil if not so many
argument."
^self getSystemAttribute: 2 + i
