Show all available versions of packages from YUM


Sometimes you may wish to see not only the version of a package you currently have installed but also the versions that are available for installation.  Using following command, you can find out.

yum --showduplicates list package | expand

And here is the output you would expect using PHP as the example.

[jhudgins@www ~]$ sudo yum --showduplicates list php | expand
[sudo] password for jhudgins:
