More man pages now rendered at man7.org

As detailed in this blog post, I've expanded the set of man pages rendered in HTML at http://man7.org/linux/man-pages/ to include pages in addition to those provided by the man-pages project. This change has several purposes. One main purpose is to provide a up-to-date and regularly updated HTML renderings of these man pages. (Most online man page renderings are out-of-date to some extent--in some cases, extremely out of date.) The other main purpose is to provide information on where to report bugs in each man page. To this end, each HTML rendering includes a COLOPHON that describes the origin of the page, notes the date when it was extracted, and provides information on where to report bugs in the page. (The man-pages project has already done this since December 2007, with the result that many more man page bugs are nowadays reported.)

Currently, man pages from nearly 40 projects are rendered, raising the number of pages rendered at man7.org from around 950 to around 1750. The projects that I have so far included have a bias that matches my interests: man-pages, projects related to low-level C and system programming (e.g., the ACL and extended attribute libraries), toolchain projects (e.g., gcc, gdb, Git, coreutils, binutils, util-linux), and other relevant tools (kmod, strace, ltrace, procps, expect) and tools relevant to manual pages (e.g., groff, man-db). The full list of projects and the corresponding man pages that are rendered can be found in the man pages by project index. I'm open to adding further projects to the rendered set, if they seem relevant. If you think there is a project that should be added, take a look at this blog post.

man-pages-3.51 is released

I've released man-pages-3.51. The release tarball is available on kernel.org. The browsable online pages can be found on man7.org. The Git repository for man-pages is available on kernel.org.

There are no content changes in this release: it consists purely of changes to comments inside the source of every manual page, in order to arrange the copyright and license sections into a standard order. The intent is to make it easier for scripts to parse the manual page sources to obtain the copyright and license of a page. For more details, see the changelog.

I've released man-pages-3.48. The release tarball is available on kernel.org. The browsable online pages can be found on man7.org. The Git repository for man-pages is available on kernel.org.

• A new perfmonctl(2) page, written by Ivana Varekova, documents the IA-64-specific system call of the same name.
• Two new pages by Ulrich Drepper, gai.conf(5) and nss(5), document configuration files of the same name.
• The clock_getres(2) page adds descriptions of the new clocks CLOCK_REALTIME_COARSE and CLOCK_MONOTONIC_COARSE, and CLOCK_BOOT_TIME. Thanks to Cyril Hrubis.
• The ptrace(2) page adds descriptions pf the new commands PTRACE_GETREGSET, PTRACE_SETREGSET, and PTRACE_SEIZE. Thanks to Denys Vlasenko.

HTML man-pages on kernel.org now redirect to man7.org

While things were repaired following the 2011 kernel.org break in, it ceased to be possible to update the HTML man pages renderings that I have for a few years maintained there. So I started placing updated renderings on my own domain, man7.org. Even after the kernel.org infrastructure was fully restored, it was still somewhat cumbersome to update 2000+ HTML pages at that location, so I subsequently continued to update the renderings at only man7.org.

Notwithstanding the fact that they are now significantly out of date, the kernel.org renderings have continued to see a lot of traffic. For that reason, I've asked the kernel.org admins to set redirects from the URLs on kernel.org to equivalent URLs on man7.org. All old links should just work; please let me know if there are any breakages.

man-pages-3.47 is released

I've released man-pages-3.47. The release tarball is available on kernel.org. The browsable online pages can be found on man7.org. The Git repository for man-pages is available on kernel.org.
