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

You forgot a dot in front of the asterisk:

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

On OpenSUSE, RedHat, Gentoo you have to use Perl version of rename. This answer shows how to obtain it. On Arch, the package is called perl-rename.
