man-pages-5.00 is released

I've released man-pages-5.00. The release tarball is available on The browsable online pages can be found on The Git repository for man-pages is available on

This release resulted from patches, bug reports, reviews, and comments from around 130 contributors. The release is rather larger than average, since it has been nearly a year since the last release. The release includes more than 600 commits that changed nearly 400 pages. In addition, 3 new manual pages were added.

Among the more significant changes in man-pages-5.,00 are the following:

  • A new page, bpf-helpers(7), documents the helper functions that the kernel provide for eBPF programs to call. This page is autogenerated from kernel files, and was brought to life in the man-pages project by Quentin Monnet.
  • Various updates to the perf_event_open(2) page by Vince Weaver.
  • A new s390_guarded_storage(2) page by Eugene Syromyatnikov documents the s390-specific system call of the same name.
  • The addition of many formerly absent architecture-specific system calls in the table of system calls shown syscalls(2).
  • A significant overhaul of the lirc4) page by Sean Young.
  • Many additions to the proc(5) page.
  • Much of the detail on socket address families in the rather overloaded socket(2) page has now been moved to a new address_families(7) page.
  • A large number of additions, mostly by me, in the capabilities(7) page.
  • Many improvements, all by me, in the discussion of ancillary data in the unix(7) page.
In addition, two pages have been removed in this release after encouragement from Ingo Schwarze: mdoc(7) and mdoc.samples(7). As the commit message notes, groff_mdoc(7) from the groff project provides a better equivalent of mdoc.samples(7) and the mandoc project provides a better mdoc(7). And nowadays, there are virtually no pages in man-pages that use mdoc markup.

Again special thanks to Eugene Syromyatnikov, who contributed nearly 30 patches to this release!

This is encouraging. Sometimes I thought man pages have become an afterthought on GNU/Linux (but never got into doing something against that myself much...)
Thank you!

Good to know about the man page of bpf-helpers. The link to bpf-helpers does not point to the right page. Please change that.
