List of installed repositories (yum)

In CentOS how can I get a list of installed repositories?

yum repolist
yum repolist enabled

shows all enabled repositories. These two commands are identical.

yum repolist disabled

shows disabled repositories.

yum repolist all

shows everything.

This is the path of yum repository

[root@localhost yum.repos.d]# pwd

/etc/yum.repos.d

This is the content of that directory

[root@localhost yum.repos.d]# ll
total 60
-rw-r--r-- 1 root root  179 Jul 17 11:56 adobe-linux-i386.repo
-rw-r--r-- 1 root root 1926 Jun 26 14:59 CentOS-Base.repo
-rw-r--r-- 1 root root  637 Jun 26 14:59 CentOS-Debuginfo.repo
-rw-r--r-- 1 root root  626 Jun 26 14:59 CentOS-Media.repo
-rw-r--r-- 1 root root 2593 Jun 26 14:59 CentOS-Vault.repo
-rw-r--r-- 1 root root  912 Jan 23  2011 elrepo.repo
-rw-r--r-- 1 root root  957 May  9 21:25 epel.repo
-rw-r--r-- 1 root root 1056 May  9 21:25 epel-testing.repo

The difference between yum.conf and yum.repos.d is in earliar system yum.conf (/etc/yum.conf) was using, within a single file we have to configure everything it was very congesting so now what they did is, they created several repo files, instead of one repo file and all the repos are kept under /etc/yum.repos.d/ directory.
