Yum whatprovidesの紹介

yumで特定のパッケージを検索するとき、yum searchやyum listは有名ですが、yum whatprovidesというコマンドもあります。

例えばlibyamlを検索するとき、それぞれこんな感じで実行できます。

yum search libyaml

yum list libyaml

yum whatprovides libyaml

yum search libyaml

yum list libyaml
2017-02-05_yum2.png

yum whatprovides libyaml
2017-02-05_yum3.png

更にyum whatprovidesはファイルがどのパッケージからインストールされるのかを検索することも可能です。

yum whatprovides '*lib64/libyaml-0.so.2'

CentOS・RHELでyumでの構築時に依存パッケージをみつからなくて困ったとき、yum whatprovidesはとても重宝します。
