How to list installed packages from a given repo using yum [closed]

Question

I want to list all packages I have installed on a system from a given repo using yum. Usually to do this I use yum list installed | grep "something". But now I am faced with a problem. The repo I am interested in does not have that "something" for me to grep. The packages from that repo do not have any distinctive characteristics. How do I list them?

I looked through yum man pages but did not find anything. I wonder if there are other commands I could use.

Answer 1

Try

yum list installed | grep reponame

On one of my servers:

yum list installed | grep remi ImageMagick2.x86_64                       6.6.5.10-1.el5.remi          installed memcache.x86_64                          1.4.5-2.el5.remi             installed mysql.x86_64                              5.1.54-1.el5.remi            installed mysql-devel.x86_64                        5.1.54-1.el5.remi            installed mysql-libs.x86_64                         5.1.54-1.el5.remi            installed mysql-server.x86_64                       5.1.54-1.el5.remi            installed mysqlclient15.x86_64                      5.0.67-1.el5.remi            installed php.x86_64                                5.3.5-1.el5.remi             installed php-cli.x86_64                            5.3.5-1.el5.remi             installed php-common.x86_64                         5.3.5-1.el5.remi             installed php-domxml-php4-php5.noarch               1.21.2-1.el5.remi            installed php-fpm.x86_64                            5.3.5-1.el5.remi             installed php-gd.x86_64                             5.3.5-1.el5.remi             installed php-mbstring.x86_64                       5.3.5-1.el5.remi             installed php-mcrypt.x86_64                         5.3.5-1.el5.remi             installed php-mysql.x86_64                          5.3.5-1.el5.remi             installed php-pdo.x86_64                            5.3.5-1.el5.remi             installed php-pear.noarch                           1:1.9.1-6.el5.remi           installed php-pecl-apc.x86_64                       3.1.6-1.el5.remi             installed php-pecl-imagick.x86_64                   3.0.1-1.el5.remi.1           installed php-pecl-memcache.x86_64                  3.0.5-1.el5.remi             installed php-pecl-xdebug.x86_64                    2.1.0-1.el5.remi             installed php-soap.x86_64                           5.3.5-1.el5.remi             installed php-xml.x86_64                            5.3.5-1.el5.remi             installed remi-release.noarch                       5-8.el5.remi                 installed 

It works.
