Thanks again. However, note that with that pattern or any other pattern containing no alphabetic character, -i is useless. It may even make sense for grep to detect the contradiction and automatically ignore that option. Omitting the -i will not only avoid the bug in older grep versions [2.6..2.13], but it will make your grep command significantly more efficient, since it will not have to perform case-conversion internally.
