[opensuse] Globbing broken in bash in 11.1 (really serious bug)
Hello, I just noticed a really serious bug in bash filename globbing: $ echo /B* $ echo /[A-C]* /bin /boot This is on an ext3 filesystem, which should clearly be case-sensitive! BTW: I found out about this bug by running $ rm -rf /some/dir/[A-Z]* :-/ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

You're making unwarranted assertions. This is an option that you can control. Here is a brief excerpt from the BASH manual page: "If the shell option nocaseglob is enabled, the match is performed without regard to the case of alphabetic characters."

Thanks to all who replied to this mail so far. But this is also with nocaseglob=off and LC_COLLATE=C: $ shopt|grep case nocaseglob off nocasematch off $ LANG=C echo /[A-C]* /bin /boot $ LANG=C locale | grep COLLATE LC_COLLATE="C" $ So I still don't see a justification for such a behavior. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

This changes the environment for running the echo command, it does not affect the globing which occurs before the command is run. You want: LANG=C; echo /[A-C]* On my system: $ mkdir test $ cd test $ touch b B $ echo [A-C]* b B $ ( LANG=C; echo [A-C]* ) B $ echo [A-C]* b B $ env | grep -e ^LANG -e ^LC LANG=en_US.utf8 LANGUAGE=en_US $ -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/

Arghs! Of course, you're right! Thanks! -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hmm, maybe you should open a bug report. Philipp -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

What's your locale settings? [A-C] means different things depending on your LC_COLLATE setting. It might mean [ABC], [AaBbC], [AbBcC], or even larger sets of characters (e.g., involving accents) If you want [A-C] to mean [ABC] you should set LC_COLLATE to "C" or "POSIX".
BTW: I found out about this bug by running
$ rm -rf /some/dir/[A-Z]*
That's unfortunate, but it's not a bug. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/

Very possibly a feature not a bug. What is the output of running locale? If LC_COLLATE is set to something else than C or POSIX bash is behaving like it's intended as (See »info '(bash.info.gz)Pattern Matching'« on '[...]'). That info page also tells you a way how to fix it. An alternative is to set LC_COLLATE=C before running these commands.
