Better uses forward slashes to avoid potential issues with quoting.

You are adding two elements (dirname and basename) to a new Array.  What for?

Also, what is the test at the end of the line supposed to do?

Here you are iterating through an Array which you know to always only
contain 1 element (a nested Array with two elements, see above).  It
does not make any sense to use an Array.

You rather want

# all numbers yield one dash
new_file = file.sub /\A\d+/, '-'

or

# each number gets its own dash
new_file = file.sub(/\A\d+/) {|m| '-' * m.length}

As far as I can see myFile is undefined here.

Overall the logic is quite dark to me...
