我在man -k .or中遇到了异常的 manpath apropos .：
重复演出：
$ man -k . | grep -w apropos man(1), apropos(1), whatis(1) - display online manual documentation pages man(1), apropos(1), whatis(1) - display online manual documentation pages $ man -k . | wc -l 15256 $ man -k . | sort -u | wc -l 11457
某些手册页可以通过 显示
man <name>但无法通过 进行过滤man -k .，例如：$ man fzf | sed -r '/^\s*$/d' | head -3 fzf(1) fzf - a command-line fuzzy finder fzf(1) NAME fzf - a command-line fuzzy finder $ man -k . | grep fzf # can be found in `/usr/local/share/man` $ fd --glob "*fzf*" /usr/local/share/man /usr/local/share/man/man1/fzf-tmux.1 /usr/local/share/man/man1/fzf.1
这里是环境：
# /etc/man.conf
$ cat /etc/man.conf | sed -r '/^(#.*)$/d;/^\s*$/d'
