Currently the mksh man page will not display on a base FreeBSD install, stating that groff is required to format the page: $ man mksh This manpage needs groff(1) to be rendered First install groff(1): pkg install groff Renames the src mksh.1 and passes it through mandoc to generate a man-compatible page to then be installed with the package.
