The state of online indices of manual pages is a sad one. Existing sites
only offer you a single version of a man page: From one origin, and often
only in a single language. Most don't even tell you where the manual
actually originated from, making it very hard to determine whether the
manual you found actually applies to your situation and even harder to find
a manual from a specific system. Additionally, some sites render the manuals
in an unreadable way, don't correctly handle special formatting - like
tables - or don't correctly display non-ASCII characters.
Manned.org was created in order to improve this situation. This site aims to index the manual pages from a variaty of systems, both old and new, and allows you to browse through the various versions of a manual page to find out how each system behaves. The manuals are stored in the database as UTF-8, and are passed through groff to render them in (mostly) the same way as they are displayed in your terminal.
You can link to specific packages and man pages with several URL formats. These URLs will keep working in the future, so you should not have to worry about eventual dead links.
The following URLs are available to refer to an individual man page:
Currently, the last three URLs will perform a redirect to the
appropriate permalink URL, but this may change in the future.
In all URLs where an optional
.<section> can be provided,
the search is performed as a prefix match. For example, /cat.3 will provide the
cat.3tcl man page if
cat.3 version is available. Linking to the full
section name is also possible: /cat.3tcl. If no
section is given and multiple sections are available, the lowest section
number is chosen.
Linking to individual packages is also possible. These pages will show a listing of all manual pages available in the given package.
Note that this site only indexes packages that actually have manual pages; Linking to a package that doesn't have any will result in a 404 page.
All man pages are fetched right from the (binary) packages available on the
public repositories of Linux distributions. In particular:
Although further development of this site is a bit stalled at the moment,
I'd love to index the manuals of most major Linux distributions in the
future. Fedora and OpenSUSE, in particular, are interesting targets to
It would also be great to index a few more non-Linux systems such as other BSDs, Solaris/Illumos and Mac OS X. Unfortunately, those don't always follow a binary package based approach, or are otherwise less easy to properly index.
In general, systems that follow an entirely source-based distribution approach can't be indexed without compiling everything. Since that is both very resource-heavy and open to security issues, there are no plans to include manuals from such systems at the moment. So unless someone comes with a solution I hadn't thought of yet, there won't be any Gentoo manuals here. :-(
This site isn't nearly as awesome yet as it could be. Here's some ideas that would be nice to have in the future:
All manual pages are copyrighted by their respective authors. The manuals have been fetched from publically available repositories of free and (primarily) open source software. The distributors of said software have put in efforts to only include software and documentation that allows free distribution. Nonetheless, if a manual that does not allow to be redistributed has been inadvertently included in our index, please let me know and I will have it removed as soon as possible.
