In addition to man and pinfo, developers may also choose to include documentation in their application's RPM distribution package. When the package is installed, files recognized as documentation are moved to /usr/share/doc/packagename. Software package builders may include anything deemed helpful as a complement to, but not duplicating, man pages. GNU packages also use /usr/share/doc to supplement info nodes.

Most packages include files describing package distribution licensing. Some packages include extensive PDF- or HTML-based documentation. Accordingly, a useful package browsing method is pointing a browser of choice to file:///usr/share/doc and utilizing a mouse.

[student@desktopX ~]$ firefox file:///usr/share/doc

Some packages come with extensive examples, configuration file templates, scripts, tutorials, or user guides. Browse /usr/share/doc/vsftpd-* as an example. Some documentation is sparse; the zip utility includes the compression algorithm used and little else. Other packages includes large user manuals or developer guides, or electronic copies of related, published books.

Note

Developers may choose to bundle extensive documentation in a separate RPM. The gnuplot program has the extra gnuplot-doc package, which must be installed separately. Other similar packages to browse include bash-doc and samba-doc. Often, extra packages are found in Red Hat Enterprise Linux's Optional software channel.

Many packages also include developer documentation, such as an Application Programming Interface (API) specification, provided in a package with a name ending in -devel or similar. Packages may include additional files, such as headers; useful documentation usually only needed for software development or compiling.

Note

The kernel itself has a significant documentation package. The kernel-doc package is a treasure of kernel, driver, tuning, and advanced configuration information. Experienced system administrators regularly research kernel-doc files.

Hello,I am trying to finish up Lab 3 of the Chapter 15 Comprehensive Review Labs in RH124, and when I type in sudo dnf install zsh for the 6th specification of the lab, I get an error message basically saying that it failed to download metadata for the repo 'ansible-2.9-for-rhel-9-x86_64-rpms', and that they could not download repomd.xml. It provided a 404 status code.Can someone please let me know what the problem is, and if there is a current workaround? Thanks.
