See what happens when you execute the following commands in order:
Code:
touch open.txt .hidden.txt
ls -l		# will not list .hidden.txt
ls -l  *.txt	# will not list .hidden.txt
ls -l  .*.txt	# will not list open.txt
ls -la *.txt	# will not list .hidden.txt
ls -la .*.txt	# will not list open.txt
ls -la		# will list both open.txt and .hidden.txt

OK. I see the difference now.
So, if I don't expect and/or want to list any files starting with a ., I can safely omit the .*.txt and .*.prg parts. Right ?

Yes.

Note that your original problem statement only talked about the trailing filename extensions and never gave any specification of the leading part of the filenames. Therefore, I needed to include those to provide an equivalent list of files since you were using ls -la in your find -exec clause. If you don't want to process hidden files, why did you use ls -la?

I use ls -la as a matter of habit. LOL. However, it had no effect on my results.

No effect other than to make your script run just a little bit slower; consume a few more system resources; and, if there are other users on your system, make the system a little bit slower for those other users.
