?  workplace man -k zipzip: nothing appropriate.

出現這種情況，是索引庫沒有建立。

 

man 和 whatis 共用一個索引庫的。

我們使用  man whatis 進行查看：

       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:

所以進行執行 mandb 就行了。 老版本的 linux 需要執行： /usr/sbin/makewhatis

這些命令都是在 root 模式下執行。執行後我們重新查看：
