Interesting. I see the same behavior. Near as I can tell bash decided that the alphabet is: aAbBcCdD... I wouldn't expect that to be the case but when I played around with various file name that was the behavior I saw. So [a-c] includes upercase B while [a-b] does not. 'ls [A-c]*' will show Berry but not apple. On Fri, 2015-06-19 at 09:29 -0400, Brett Russ wrote:
Can someone explain this to my evidently inadequately caffeinated brain? I was trying to use a lower case character range wildcard to list all files not starting with an uppercase letter and I noticed it wasn't working as I'd expect. So I created this simple example and still don't understand what's happening.
Dir with two files:
brett@spider /tmp/test $ \ls apple Berry
This is what I'd expect to see:
brett@spider /tmp/test $ \ls [a-b]* apple
This makes no sense. Is this a bug?:
brett@spider /tmp/test $ \ls [a-c]* apple Berry
From here on are just a few extra examples confirming the oddity of the above.
brett@spider /tmp/test $ \ls [a]* apple
brett@spider /tmp/test $ \ls [b]* ls: cannot access [b]*: No such file or directory
brett@spider /tmp/test $ \ls [c]* ls: cannot access [c]*: No such file or directory
brett@spider /tmp/test $ \ls a* apple
brett@spider /tmp/test $ \ls b* ls: cannot access b*: No such file or directory
brett@spider /tmp/test $ \ls c* ls: cannot access c*: No such file or directory
