How to search package name with some files

[Moto <nico_chen@coventive.com>]

Dear all,

If I just know one file like "abc.so.1" and I am sure that I didn't install
any package with this file. So, how do I check this file included by which
package ??

Thank you.

如果我只知道一個檔案，像是"abc.so.1" 但我確定我電腦裡面沒有
安裝任何包含這個檔案的 package，那我也如何知道該檔案屬於那一個
package ??

謝謝您
