From time to time, I was wondering what packages are available by default on this and that system, so that I could write scripts which might depend on those packages with the confidence that they are always present.

Here are the lists of packages installed by default on various linux distributions (Debian, RedHat, CentOS, Cygwin).

DEB based distributions

Debian

Debian Policy documents the base system of Debian system.

The base system consists of all those packages with priority required or important.

Those are the default installed packages in every Debian system. And can be listed with the following commands:

aptitude search ~prequired -F"%p"
aptitude search ~pimportant -F"%p"

This answer on StackExchange has more details on this topic.

RPM based distributions

When installing RedHat or CentOS, you are given the option to do software selection, among Environment Groups like Minimal, Basic Server, Virtual Host, Desktop and so on.

While the package groups installed depend on your choice, packages in core group get installed in every case, and packages in base group get installed in every case except for the Minimal environment group.

You may check what packages are contained in a group with command yum groupinfo groupname.

The output looks like this:

Group: Core
 Group-Id: core
 Description: Smallest possible installation.
 Mandatory Packages:
    ...
 Default Packages:
    ...
 Optional Packages:
    ...
 Conditional Packages:
    ...

We may find that each group may contain mandatory, default, optional and conditional packages.

  • Mandatory packages are always installed if the group is installed;
  • Default packages are selected by default when installing the group;
  • Optional packages are deselected by default when installing the group;
  • Conditional packages are mandatory if the packages require them are going to be installed.

Packages in each group are defined in a comps XML file, which can be found in /var/cache/yum/*/comps*.xml. See comps for details.

RedHat

To check currently installed packages, run rpm -qa.

Here is the default installed packages on Red Hat Enterprise Linux 7.2 on AWS (ami-0dd8f963):
