Renaming a large amount of files while retaining the order?

[Panderz]

Hi all, I've got a possibly nooby question, I'm not sure. This is my firt forum post btw ^_^ .I've downloaded about 100 videos off of youtube, but alot of them are named something different even though they're from the same playlist. What I want to do is just rename the file to Mpt(order number here).mp4. I know what I want to do, but am not sure about the syntax.

So what I have in mind is something like this...

mv Mass(number in series here, ideally I would like it to read the number as a variable).mp4 Mpt(the var number here).mp4

Can anyone help me??

more details about naming convention would be nice, some examples?

The majority of the files I dl'd are named "Mass Effect 3 PC Sentinel INSANITY pt.(insert number here).mp4. I want to name as Mpt(insert number here).mp4

Is there no help for a computer-illiterate's son?

for f in "Mass Effect 3"*[0-9].mp4; do n=${f%.*}; n=${n##*[^0-9]}; echo mv "$f" "Mpt${n}.mp4"; done

rename -nv 's/.*[^0-9]([0-9]+[.]mp4$)/Mpt$1/' "Mass Effect 3"*[0-9].mp4

both of these won't actually rename files but print out what would happen if echo/n (bolded) were not present.

Thank you very much
