I am trying to rename .srt files. The files presently have names such as this:

StargateSG1.s02e19.One.False.Step.AC3.DVDRip.DivX-AMC.srt

I would like the resulting file to be :

StargateSG1.s02e19.srt

After studying rename for awhile I came up with the command:

rename -n 's/(\d{19})/$1.srt/' *.srt

Which is supposed to save the first 19 characters and remove the rest then appending .srt to the first 19 characters. It's not working and I'm stumped. I have searched this out and can't find any help, as far as I can tell this should work. Any help would be greatly appreciated. Thanks

$ rename -n 's/^(.{18}).*$/$1.srt/' *.srt
StargateSG1.s02e19.One.False.Step.AC3.DVDRip.DivX-AMC.srt renamed as StargateSG1.s02e19.srt

You had 2 problems:

  1. \d stands for any digit, while you need . which is any character.
  2. You didn't match the rest of the filename, so the replacement operation wouldn't have removed it.
  • Can you please explain the .*$ and the ^ ? – Widgeteye Sep 1 '16 at 1:51
  • .* is any number of any characters. ^ is the start of input, $ is the end of input, their purpose is to ensure that we match the whole input from start to end, instead of just a portion of the input. – dezlov Sep 1 '16 at 13:55
