man命令使用查询出现的小错误

使用man查询命令时出现类似的一行：

man abc

Cannot open the message catalog "man" for locale "zh_CN.UTF-8"

(NLSPATH="/usr/share/locale/%l/LC_MESSAGES/%N")

No manual entry for abc

在网上找了解决方法——————将en下的man复制过来就可以了：

cp /usr/share/locale/en/LC_MESSAGES/man /usr/share/locale/zh/LC_MESSAGES/

另一个办法不起作用，就是修改/etc/profile后面加一行 unset MANPATH,然后我source一下，问题依旧。

具体的原因，用strace命令查看下就知道了，这是我在网上找的：

用strace看了一下，发现在最后：
