Pls go through it, no more doughts remain regarding yum commands:

# yum update

List all installed packages, enter:
# rpm -qa

# yum list installed

Find out if httpd package installed or not, enter:
# rpm -qa | grep httpd*
# yum list installed httpd

To check for and update httpd package, enter:
# yum update httpd

Search httpd and all matching perl packages, enter:
# yum list {package-name}
# yum list {regex}
# yum list httpd
# yum list perl*
