Rename files using regular expression in linux

Question

I have a set of files named like:

Friends - 6x03 - Tow Ross' Denial.srt
Friends - 6x20 - Tow Mac and C.H.E.E.S.E..srt
Friends - 6x05 - Tow Joey's Porshe.srt

and I want to rename them like the following

S06E03.srt
S06E20.srt
S06E05.srt

what should I do to make the job done in linux terminal? I have installed rename but U get errors using the following:

rename -n 's/(\w+) - (\d{1})x(\d{2})*$/S0$2E$3\.srt/' *.srt

Answer 1

Not every distro ships a rename utility that supports regexes as used in the examples above - RedHat, Gentoo and their derivatives amongst others.

Alternatives to try to use are perl-rename and mmv.
