➜  workplace man -k zip
zip: nothing appropriate.

出现这种情况，是索引库没有建立。

man 和 whatis 共用一个索引库的。

我们使用 man whatis 进行查看：

       index databases are used during the search, and are updated by  the  mandb  pro‐
       gram.   Depending  on your installation, this may be run by a periodic cron job,
       or may need to be run manually after new manual pages have been  installed.   To
       produce  an  old  style  text  whatis database from the relative index database,
       issue the command:

所以进行执行 mandb 就行了。老版本的 linux 需要执行： /usr/sbin/makewhatis

这些命令都是在 root 模式下执行。执行后我们重新查看：
