Re: O_DIRECT support in dd
The man pages at: http://www.gnu.org/software/coreutils/manual/html_chapter/coreutils_11.html#SEC65 Do not document an iflag parameter. Is this simply an error in the documentation? It looks like I'm still using coreutils 5.2, so I guess I'll have to upgrade. I'm wondering now why there was over a year between the release of 5.2.1 and 5.92, with nothing in between.

Nope.

Unfortunately they are not generated automatically, as they should be. I just did my quick best to bring them up to date, and the changes should be propagated to the web server in a day or so. In the meantime you can just download the latest version of coreutils and look at the documentation bundled with it.

O_DIRECT support in dd
I searched the archives and found a thread from over a year ago talking about adding support to dd for O_DIRECT, but it is not documented in the man pages. Did the man pages not get updated, or did this patch not make it in? If O_DIRECT is supported, but not documented, then I wonder: does dd use aio so as to keep the IO pipelined, since a blocking read/write would only be able to access one file/disk at a time? ___ Bug-coreutils mailing list Bug-coreutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-coreutils
