Hi,
Been trying to get BASH to sort set characters in dictionary order.
I typed "locale" and it shows LC_COLLATE and LC_ALL are set to "C"
thought that was enough to work,
however when i type metacharacters: set character; any character,
something like this:
ls [a-cx-y]*
bash does not sort in dictionary order; file "Binarc" does not
list.
*OF*COURSE* it doesn't. Unix is _case_sensitive_. You specified a lower-
case only (in the C locale) pattern. Naturally, it doesn't match a file
with an upper-case character in it.
Note: in the 'C' locale, characters are sorted on the underlying byte value.
Thus you will get all the upper-case matches before any lower-case match.
To get upper-and-lower case files in the C locale, you will have to use:
ls [A-CX-Ya-cx-y]*
IF you speciy a different charset for collating, you _may_ get upper/lower
case characters sorted adjacently. See the specifications for the charset
in question.
Thanks for reply!
I meant LC_COLLATE being set to en_US.UTF-8 not C.
AH. you lied (not necessarily maliciously, or intentionally) about the
nature of the problem. disregard my rant.
The short answer to the revised situation is 'it depends on how the charset
collating sequence is deifined'. AND _which_ release of FreeBSD you are
using, and thus which version of bash.
I have been digging around and discovered linux's bash is not
working correctly on this matter and numerous users have file bug
reports about it. FreeBSD's bash is fine:

https://bugs.launchpad.net/ubuntu/+source/bash/+bug/120687
http://teaching.idallen.com/net2003/06w/notes/character_sets.txt
i will continue using either character classes and upper/lower case
charsets when defining wildcards
thanks for the help.
