I can't see you avoiding quotes etc, but extending on John's comment,
the obvious next step would be to run everything in a loop i.e. place
all the commands into a list and create a loop that ran each command
in the list.
Almost all editors support macros - most editors support some form of
language sensitive editing (NOT the prompt call parameters style but
rather help with the syntax via a 'form' style of fill-in) that will
allow you to reduce typing effort. But macros would be the first and
easiest choice for this activity.
