Although this used to be in POSIX and is widely implemented, it does not make much sense. POSIX.1-2008 leaves ranges undefined in locales other than the POSIX locale. Therefore, it is an option to disable collation for ranges and just compare character codes. The problem started to occur more often with the new collation code, which supports UTF-8 and uses CLDR's different collation order, but strange results from [A-Z] can be encountered in much older versions. Bash behaves similarly to sh, but supports 'shopt -s globasciiranges' to disable collation. In some sense this is strange, an option that needs to be enabled to provide the behaviour most people expect. Alternatively, the pattern could be rewritten to be locale-sensitive: [[:upper:][:digit:]]*[[:upper:][:digit:]] -- Jilles Tjoelker _______________________________________________ email@example.com mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
