In my view, the standard is quite clear: "If any character (ordinary, shell special, or pattern special) is quoted, that pattern shall match the character itself." That sentence applies to pattern matching notation as a whole. Bracket expressions are a part of pattern matching notation. There is no language anywhere in the standard that excludes bracket expressions from the sentence quoted. http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_13 Thanks, - M.
