No, it's the specification of how character ranges in glob(3) and fnmatch(3) work. In effect, character ranges like [a-z] must be treated as ranges of *collating elements*, not byte ranges, and in your locale, <a> and <A> are considered to be the same collating element, so [a-z] matches both upper- and lower-case Latin letters. This is documented, very obliquely, in sh(1), which also tells you the workaround: a character class. A character class matches any of the characters between the square brackets. A locale-dependent range of characters may be specified using a minus sign. A named class of characters (see wctype(3)) may be specified by surrounding the name with `[:' and `:]'. For example, `[[:alpha:]]' is a shell pattern that matches a single let- ter. So, to match only lower-case letters regardless of your current locale setting, you must use the correct character class: $ locale LANG=pt_BR.UTF-8 LC_CTYPE="pt_BR.UTF-8" LC_COLLATE="pt_BR.UTF-8" LC_TIME="pt_BR.UTF-8" LC_NUMERIC="pt_BR.UTF-8" LC_MONETARY="pt_BR.UTF-8" LC_MESSAGES="pt_BR.UTF-8" LC_ALL= $ ls D E F a b c $ ls [[:lower:]]* a b c The same applies to character class ranges in regular expressions, not just glob(3) patterns. -GAWollman _______________________________________________ email@example.com mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
