Sarah Jelinek Rich Lowe, richlowe@richlowe.net What specifically is the proposal that we are reviewing? Addition of the -s and -S options to the 'zfs list' command for selecting columns to display and sort from. See svcs(1) for an example. This ARC case is generated from an opensolaris sponsor request for RFE 6276925 option to sort 'zfs list' output. Solution provided by Richard Lowe, sponsored by Sarah Jelinek. Summary: These options are being added to enable sorting of the 'zfs list' output. -s col Sorts output by column. col should be a column name. See COLUMNS below for available columns. Multiple -s options are evaluated left to right, in descreasing order of importance. So for example, the command 'zfs list -s avail -S refer' will be in ascending order of space available and for the datasets where that is equal, sort in descending order of space referenced. -S col Sorts by col in the opposite order as option -s. Numeric types sort in ascending/descending order. String types sort in alphabetical order. Types inappropriate for a row sort that row to the literal bottom, regardless of the specified ordering. For example, the property 'available' makes no sense on a snapshot. If no sorting options are specified the existing behavior of 'zfs list' is preserved. ************************************************************** COLUMNS: type creation used available referenced compressratio mounted origin quota reservation volsize volblocksize recordsize mountpoint sharenfs checksum atime devices exec setuid readonly zoned snapdir aclmode aclinherit This project is requesting approval for patch binding.

OK, I see that multiple -s and -S args *are* listed in the man page. I also note that we already do comma seperated lists in zfs list (see -o). Might it then be an idea to allow comma seperated lists in addition to multiple arguments (in order to mix and match reverse sorting of multiple columns)? I also see -r is not available so we can just ditch that idea. alan. -- Alan Hargreaves - http://blogs.sun.com/tpenta Staff Engineer (Kernel/VOSJEC/Performance) Product Technical Support (APAC) Sun Microsystems From sacadmin Wed May 10 09:26:41 2006 Received: from sunmail3.sfbay.sun.com (sunmail3.SFBay.Sun.COM [129.149.247.180]) by sac.sfbay.sun.com (8.13.6+Sun/8.13.6) with ESMTP id k4AGQeQx019129 for ; Wed, 10 May 2006 09:26:40 -0700 (PDT) Received: from nwk-avmta-1.SFBay.Sun.COM (nwk-avmta-1.SFBay.Sun.COM [129.149.246.28]) by sunmail3.sfbay.sun.com (8.11.7p1+Sun/8.11.7/ENSMAIL,v2.2) with ESMTP id k4AGQcO23482 for <@sunmail2.sfbay.sun.com:psarc@Sun.COM>; Wed, 10 May 2006 09:26:39 -0700 (PDT) Received: from pmxchannel-daemon.nwk-avmta-1.sfbay.Sun.COM by nwk-avmta-1.sfbay.Sun.COM (Sun Java System Messaging Server 6.2 (built Dec 2 2004)) id <0IZ200D015O82V00@nwk-avmta-1.sfbay.Sun.COM> for psarc@Sun.COM (ORCPT psarc@Sun.COM); Wed, 10 May 2006 09:26:32 -0700 (PDT) Received: from sfbaymail1sca.SFBay.Sun.COM ([129.145.154.35]) by nwk-avmta-1.sfbay.Sun.COM (Sun Java System Messaging Server 6.2 (built Dec 2 2004)) with ESMTP id <0IZ20060P5O8H360@nwk-avmta-1.sfbay.Sun.COM> for psarc@Sun.COM (ORCPT psarc@Sun.COM); Wed, 10 May 2006 09:26:32 -0700 (PDT) Received: from bags.sfbay.sun.com (bags.SFBay.Sun.COM [129.146.228.222]) by sfbaymail1sca.SFBay.Sun.COM (8.12.10+Sun/8.12.10/ENSMAIL,v2.2) with ESMTP id k4AGQWoe010795; Wed, 10 May 2006 09:26:32 -0700 (PDT) Received: from bags.SFBay.Sun.COM (localhost [127.0.0.1]) by bags.sfbay.sun.com (8.13.5+Sun/8.13.5) with ESMTP id k4AGQVHu481244; Wed, 10 May 2006 09:26:31 -0700 (PDT) Received: (from jwadams@localhost) by bags.SFBay.Sun.COM (8.13.5+Sun/8.13.5/Submit) id k4AGQVGL481243; Wed, 10 May 2006 09:26:31 -0700 (PDT) Date: Wed, 10 May 2006 09:26:31 -0700 From: Jonathan Adams Subject: Re: Fast track: PSARC/2006/308 zfs list option In-reply-to: <4460E184.6010503@sun.com> To: Sarah Jelinek Cc: psarc@Sun.COM, richlowe@richlowe.net Message-id: <20060510162631.GA481156@eng.sun.com> MIME-version: 1.0 Content-type: text/plain; charset=us-ascii Content-transfer-encoding: 7BIT Content-disposition: inline X-PMX-Version: 5.1.2.240295 References: <4460DA53.8030807@sun.com> <4460E184.6010503@sun.com> User-Agent: Mutt/1.4.2.1i Status: RO Content-Length: 1474 On Tue, May 09, 2006 at 12:37:56PM -0600, Sarah Jelinek wrote: > > -s col Sorts output by column. col should > be a column name.

Isn't this not getopts(1)-compliant: intro(1): 11. The order of the options relative to one another should not matter. I've always understood this to mean that while ordering of arguments with the *same* option letter: ps -o pid -o args can have an effect, different option letters should be independent. That would imply that: zfs list -s name -S compressratio be equivalent to: zfs list -S compressratio -s name which won't work. Perhaps something like: zfs list -s avail -s -refer zfs list -s avail,-refer would be better?

It will be sorted > based on -s and -S, if they are specified. I'm not sure I understand about the tree not being specific to list -r. How else do you see a tree structure? Or do you simply mean when using list without an argument? At any rate, I think my question still holds, but I'll be more specific. When I do a "zfs list" or "zfs list -r ", I see a bunch of datasets in a linearized tree structure. If I now add sorting to that, is the tree structure preserved, and the sorting applied only to the children of each node in the tree individually, or is the sorting applied across all datasets, destroying the tree? So if I have a couple of filesystems, each with a handful of snapshots: A April 1 A@1 April 3 A@2 April 4 A@3 April 7 B April 4 B@1 April 5 B@2 April 6 B@3 April 8 I want to sort by date, will they all be intermixed: A April 1 A@1 April 3 B April 4 A@2 April 4 B@1 April 5 B@2 April 6 A@3 April 7 B@3 April 8 or will I see the filesystems sorted by date, with the snapshots still "attached" to their filesystems, which would look like the original listing (since the default sorting at least appears to be date)? I don't think it makes sense to "sort by thread" (to use a mutt term) at any level except the top, but both sorting by thread and not are valid with other sort keys.

Look at the example that you wish the primary key to be reverse sorted. eg zfs list -s -avail,refer That's going to confuse things pretty well. alan. -- Alan Hargreaves - http://blogs.sun.com/tpenta Staff Engineer (Kernel/VOSJEC/Performance) Product Technical Support (APAC) Sun Microsystems I'm going in the World's Greatest shave for Leukaemia.

I thought it best to aim for consistency. That makes sense.
