Q. How do I list all installed packages on Linux or FreeBSD system?

A. Most Linux distributions are based upon rpm or apt-get / dpkg packaging system.

RedHat, Fedora Core, Suse Linux, Cento os all are RPM based distribution

Use rpm command as follows to list all installed packages
rpm -qa
rpm -qa | grep 'package-name'
rpm -qa | grep -i '*httpd*'

Debian or Ubuntu Linux distribution

You can use dpkg command to list all installed packages:
dpkg --list
dpkg --list | grep 'package-name'
dpkg --list | grep -i '*php*'

Task: OpenBSD list installed package

Use pkg_info command for displaying information on all installed software packages
$ pkg_info
$ pkg_info | grep 'package-name'

For packages management better is dselect. It can list, display status and choose packages for install/reinstall/uninstall.
