[Solved] Remove LaTex Tag with perl

Hi,
i am trying to remove all LaTex tags (\index{text} from a big input file, using perl. My current approach which does not work is the following.
Code:
perl -ne '$/=undef; s/\\index\{*?\}//g; print' < $CWD/$OUTPUT.txt > tmp.txt

But the tags still remain in the text. Can somebody tell my what I am doing wrong.

Regards,
Jan

Hi mortl,

At least I saw one thing wrong. Inside brackets, you need a '.' just before '*' to search any number of characters, similar to:
Code:
s/\\index\{.*?\}//g
