Yum can do more things than just a yum search $package. It also allows you to search for a package that contains a certain file. For that, you can use the yum whatprovides command.
For instance, if you want to search for what package contains the /usr/bin/node binary (for NodeJS), you can search like this.
$ yum whatprovides */usr/bin/node ... nodejs-0.10.32-1.el6.i686 : JavaScript runtime Repo : epel Matched from: Filename : /usr/bin/node nodejs-0.10.32-1.el6.x86_64 : JavaScript runtime Repo : epel Matched from: Filename : /usr/bin/node
The syntax is yum whatprovides */path/to/your/file or a wildcard, like yum whatprovides */file. To search the node binary, you can also make it shorter:
$ yum whatprovides */node ...
And there’s a few more little tricks that yum provides as well.
