Because this wil turn "dave.txt" into "davetxt", removing the period
before the extension (I see your process puts them back in after the
fact), I'd solve this with the Perl "rename" utility using
This requires that there be at least one period (the one before
the extension) after any period that is removed.

Similarly, you can consolidate all sequences of spaces in one pass:
's/ +/ /g'
Additionally, these can be combined with a semicolon in the same pass:
rename -n 's/(?<=\b[[:alpha:]])\.(?=.*\.[^.]*$)//g;s/ +/ /g'
I have one huge ugly command that cleans up the podcast filenames in
my queue, removing troublesome characters (a "#" character in the
filename trips up my player, and I don't like periods & spaces,
swapping them to underscores and then condensing multiple runs of
them down to a single underscore). Once you've gotten the command
figured out, I put it in a shell-script and don't have to ever think
about it again. (smile)

While not exactly what you're asking, for individual files, I often
use shell brace-expansion like
which can save a lot of typing. This also works nicely for taking
backups of a file like
Hope this gives you some more options to work with (and if you have
regex questions, I'm a sucker for playing with them, often hanging
out in /r/regex on Reddit helping folks there)
