In compliance with the FHS, where are man pages found?

The correct location for man pages, according to the Filesystem Hierarchy Standard (FHS), is /usr/share/man/. This directory is specifically designated for shared, architecture-independent data files, which include the manual pages for commands and libraries. Man pages provide users with documentation and information on how to use commands in the Linux environment, making this directory critical for user assistance.

The organization of the filesystem under FHS aims to create consistency across Linux distributions, thus ensuring that users can find essential documentation in the same location regardless of the specific distribution they are using. Placing man pages in /usr/share/man/ aligns with the objective of maintaining a clear and systematic directory structure.

Other choices, while they may imply locations where documentation could potentially reside, do not adhere to the FHS guidelines for man pages. For example, /opt/man/ and /var/man/ are not standard locations for manual pages, and /usr/doc/ is intended for documentation files rather than specifically for man pages. Therefore, /usr/share/man/ is the recognized and standardized directory for accessing man pages in compliance with the FHS.
