Since you decided not to tell us anything about your environment, I am left toguess that you went from a Mac to Linux. [grep] is a line-based regex engine,meaning that it can only affect text up to (but not including) the end of linecharacter (EOL). If it used to work on the Mac, that should probably be viewedas a bug in the implementation on the Mac more than anything else. The Perlregex engine can be instructed to include multiline strings (in which case youcan mess with the EOL), but this is not typically of most regex libraries.> Does anyone know how to strip out cr's from templates since this doesn't seem to work any more?Don't bother. It really isn't worth it in terms of server performance and itmakes your site very hard to read in view source. In fact, done incorrectly itcould lead to words being run together.If you are genuinely concerned about server performance, for example if you havea very slow connection to the Internet, and you are running Apache 2.0 orbetter, consider enabling mod_deflate, which will compress the text sent to thebrowser on the fly (all modern browsers handle this without a problem).
