\b won't work for filenames like abc.Xyz because . is considered a word boundary.
Hint: There is a regex symbol that matches "beginning of a string".

-
Filenames are listed one filename per line.
-woption does not help. -
Also, the regex should also work for filenames like
A123.jpg,B$$$.txt.
Note: The same also apply to script-04.sh

Can the regex detect filenames like A123 or B$$$?
