?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 bythemandbpro‐ gram.Dependingon your installation, this may be run by a periodic cron job, or may need to be run manually after new manual pages have beeninstalled.To produceanoldstyletextwhatis 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：
