It seems that ranged filename substitution sometimes doesn't work as expected. A couple of illustrations.
Source dir: ale...@ubuntu64:/tmp$ ls -la ... -rw-r--r-- 1 root root 66 2010-09-21 08:54 ahello.txt drwxr-xr-x 2 root root 6 2010-09-18 13:09 bigstore -rw------- 1 alexey alexey 1611084 2010-09-29 18:19 clipboardcache -rw------- 1 alexey alexey 1611084 2010-09-29 18:19 clipboardcache-1 -rw------- 1 alexey alexey 1611084 2010-09-29 18:19 clipboardcache-2 -rw------- 1 alexey alexey 1611624 2010-09-29 18:19 clipboardcache-3 -rw------- 1 alexey alexey 1 2010-10-04 18:31 cLnlY6 -rw------- 1 alexey alexey 6 2010-10-04 18:31 Code::Blocks-alexey drwx------ 2 alexey alexey 27 2010-09-03 01:17 codeblocks_dbgrpt-30651-20100903T011749 -rw------- 1 alexey alexey 0 2010-09-13 15:29 codeblocksIJ8lud srwx------ 1 alexey alexey 0 2010-10-04 18:31 CODEBLOCKS.socket -rw------- 1 alexey alexey 0 2010-09-03 01:17 codeblocksWrgEbU drwxr-xr-x 3 alexey alexey 16 2010-08-29 18:02 context drwxr-xr-x 3 alexey alexey 4096 2010-09-27 19:55 data ... (I've included only files begin with "b" and "c/C") Well, let us run: ale...@ubuntu64:/tmp$ shopt -u nocaseglob; shopt -s nullglob; for a in [b-c]* ; do echo $a; done bigstore clipboardcache clipboardcache-1 clipboardcache-2 clipboardcache-3 cLnlY6 codeblocks_dbgrpt-30651-20100903T011749 codeblocksIJ8lud codeblocksWrgEbU context -- All as expected.

Both letters in the range are actually latin. Here is the prof: echo "BC" | hd 00000000 42 43 0a |BC.| But the range search here is thow out only non-capital "bigstore" from the listing, and still included both-cased files begin with c/C. The fact that 'c' is in the range "B-C" looks really strange. I would expect that this range contains only "B" and C" letters. However, when directly enumerating the letters, all works ok: ale...@ubuntu64:/tmp$ shopt -u nocaseglob; shopt -s nullglob; for a in [BC]* ; do echo $a; done Code::Blocks-alexey CODEBLOCKS.socket ---------------- bash --version GNU bash, version 4.1.5(1)-release (x86_64-pc-linux-gnu) Copyright (C) 2009 Free Software Foundation, Inc.
