Actually, BRE's are widely used - a nuisance if one writes portable Bourne shell scripts. Tedickey (talk) 11:45, 4 January 2009 (UTC)Reply

Never heard of Bourne shell. I use either zsh or bash (or Windows). The languages and editors I use rely on a form of ERE but there are many languages and editors and shells out there so I don't doubt that BRE is used extensively as well. BluePlateSpecial (talk) 17:16, 4 January 2009 (UTC)Reply
