You have to prepend whatever input you produce to the second one, of course, like the ls | used above. I added it to the code.
The first code breaks the input line at _ and . as told by the field separator, set with -F. $NF is the last field ("txt"), $(NF-1) the before last field containing the date string. The use of the substr function is self explanatory, I think.
The second works similarly, but leaves the .txt extension intact.
