Sed regex does not work

Question

The following command does not return anything and i think my regex is good ?

echo 'The.Big.Bang.Theory.S07E01.VOSTFR.720p.WEB-DL.DD5.1.H.264-GKS.mkv' |\
sed -n '/The.Big.Bang.Theory*VOSTFR*720p*WEB-DL*.mkv/p'

Thanks!

Answer 1

• \\. matches the . char

• .* matches any char zero or more times:

  sed -n '/The\\.Big\\.Bang\\.Theory.*VOSTFR.*720p.*WEB-DL.*\\.mkv/p'

Answer 2

y* means zero or more y s. R* means zero or more R s. etc.

You probably want

/The\.Big\.Bang\.Theory.*VOSTFR*720p.*WEB-DL.*\.mkv/

Answer 3

Works like this :

echo 'The.Big.Bang.Theory.S07E01.VOSTFR.720p.WEB-DL.DD5.1.H.264-GKS.mkv' |\
sed -n '/The.Big.Bang.Theory.*VOSTFR.*720p.*WEB-DL.*.mkv/p'

I forgot the dots :/
