8.2.2. Listing Packages

yum list and related commands provide information about packages, package groups, and repositories.
All of Yum's list commands allow you to filter the results by appending one or more glob expressions as arguments. Glob expressions are normal strings of characters which contain one or more of the wildcard characters * (which expands to match any character multiple times) and ? (which expands to match any one character).

Note

Be careful to escape the glob expressions when passing them as arguments to a yum command, otherwise the Bash shell will interpret these expressions as pathname expansions, and potentially pass all files in the current directory that match the globs to yum. To make sure the glob expressions are passed to yum as intended, either:
  • escape the wildcard characters by preceding them with a backslash character
  • double-quote or single-quote the entire glob expression.
See Example 8.3, “Listing all ABRT add-ons and plug-ins using glob expressions” and Example 8.5, “Listing available packages using a single glob expression with escaped wildcard characters” for an example usage of both these methods.
yum list glob_expression
Lists information on installed and available packages matching all glob expressions.

Example 8.3. Listing all ABRT add-ons and plug-ins using glob expressions

Packages with various ABRT add-ons and plug-ins either begin with “abrt-addon-”, or “abrt-plugin-”. To list these packages, type the following at a shell prompt: 
~]# yum list abrt-addon\* abrt-plugin\*
