Re: [Wlug] ls character range wildcard oddity?

by Dennis Payne

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?

Re: [Wlug] ls character range wildcard oddity?

by Chris Thompson

Well, this may not get you only a subset of lower-case letters, but it does at least limit to lower case: [[:lower:]]. More details below. e.g.: ls [[:lower:]]* Regards, Chris See also: http://www.tldp.org/LDP/GNU-Linux-Tools-Summar/html/x11655.htm#STANDARD-WIL… man 7 glob ---------- Character classes and internationalization Of course ranges were originally meant to be ASCII ranges, so that "[ -%]" stands for "[ !"#$%]" and "[a-z]" stands for "any lowercase letter". Some UNIX implementations generalized this so that a range X-Y stands for the set of characters with code between the codes for X and for Y. However, this requires the user to know the character cod‐ ing in use on the local system, and moreover, is not convenient if the collating sequence for the local alphabet differs from the ordering of the character codes. Therefore, POSIX extended the bracket notation greatly, both for wildcard patterns and for regular expressions. In the above we saw three types of items that can occur in a bracket expression: namely (i) the negation, (ii) explicit single characters, and (iii) ranges. POSIX specifies ranges in an internationally more useful way and adds three more types: (iii) Ranges X-Y comprise all characters that fall between X and Y (inclusive) in the current collating sequence as defined by the LC_COLLATE category in the current locale. (iv) Named character classes, like [:alnum:] [:alpha:] [:blank:] [:cntrl:] [:digit:] [:graph:] [:lower:] [:print:] [:punct:] [:space:] [:upper:] [:xdigit:] so that one can say "[[:lower:]]" instead of "[a-z]", and have things work in Denmark, too, where there are three letters past 'z' in the alphabet. These character classes are defined by the LC_CTYPE category in the current locale. On 06/19/2015 09:58 AM, Theodore Ruegsegger wrote: > It looks like a locale issue.

Re: [Wlug] ls character range wildcard oddity?

by Theodore Ruegsegger

It looks like a locale issue. In the old "C" locale, sorting a list put all cap letters before all lowercase letters. In the "en_US.UTF-8" locale, apparently the Ubuntu default, they're sorted as in a regular dictionary, regardless of caps. For example: ls apple berry Berry charlie Hope that's more helpful than my first response!

ls character range wildcard oddity?

by Brett Russ

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 brett@spider /tmp/test $ dpkg -S `which ls` coreutils: /bin/ls brett@spider /tmp/test $ dpkg -s coreutils Package: coreutils Essential: yes Status: install ok installed Priority: required Section: utils Installed-Size: 6020 Maintainer: Ubuntu Developers <ubuntu-devel-discuss(a)lists.ubuntu.com> Architecture: amd64 Multi-Arch: foreign Version: 8.21-1ubuntu5.1 [SNIP] Thanks, Brett

I'll be doing a talk/demo of the ZFS (Zettabyte File System) naively running on Linux. This is going to be held in the campus center Rm. 129 a.k.a "Chairman's Room" at 7pm.

by Tim Keller

The next WLUG meeting is June 11th, 2015. @ 7pm. NOTE: THE MEETING WILL BE IN THE CAMPUS CENTER RM 129 aka "Chairman's Room" I will be speaking about native ZFS on linux. I'll go into the structure of ZFS and its design principles, and how it's used in production. I'll then do a demo showing off what ZFS can do and I'll create a bunch of different FS types, etc. It should be a blast. Like usual there will be refreshments available.

Hey Everybody, Our next meeting is going to be on June 11th, 2015 @ 7:00pm. The topic is going to be "ZFS on linux". What is ZFS? ZFS is a logical volume manager (LVM), raid subsystem and a file system combined. I'll be doing a deep dive on how ZFS works on linux, it's strengths and weaknesses. Snacks and refreshments will be available. I'm working with Frank to verify the location.

Next Meeting Topic: ZFS on linux?

by Tim Keller

Hey Gang, Would people find it interesting in doing either a ZFS centric meeting, or doing a compare/contrast Linux file system bonanza? Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Re: [Wlug] Great Meeting last night! Thanks Frank and Jeff!

by Jamie Guinan

Agreed, great meeting. I learned several things from Frank's talk, I had no idea about the "hot plate" and temperature issues. And it was cool to see Jeff's machine in action, despite the hiccups. I should go to more meetings. #sophisticatedcat -Jamie On Fri, 15 May 2015, Tim Keller wrote: > Hey Everybody, > > Last nights meeting was great.

A nice map of campus (with buildings unlabeled) is covered by a pop up, which tells you when Harrington was built and what ball teams like it. If you click it will change to something almost, but not entirely, unlike directions to somewhere random. >From the picture, I think it is the building just on the north side of the quad. Is that right? I expect to be there. I will sit on the brass goat and refuse to leave until someone tells me where Harrington is. Actually it may be easier than that. I think there is a map on a signpost near the fountain which is actually useful if you want to go somewhere. Or ask info in the student center. -- Keith

Re: [Wlug] Meeting Reminder Thursday May 14th 2015!

by Tim Keller

This sounds awesome. I think it would be cool to have both so we could compare/contrast the two designs. Jeff don't worry about the public speaking, as you may have noticed we're informal and pride ourselves on having more of a free form open conversion format.
