Linux check all installed packages

Linux rpm List Installed Packages Command

H ow do I list all installed packages using rpm command on CentOS/Suse/Fedora/RHEL/Scientific and Red Hat Enterprise Linux? Can you tell me the Linux command to list all rpm’s installed on the server?

The rpm command is a powerful package manager. It is used to build, install, query, verify, update, and erase individual software packages on RPM based distro such as OpenSUSE, RHEL or CentOS. The latest version of Red hat and friends recommend using the yum command or dnf command.

Linux rpm list installed packages command syntax

The rpm command has -a option to query (list) all installed packages.

List all installed packages using rpm -a option

Open the Terminal or login to the remote server using ssh client. Type the following command as root user:
# rpm -qa
Sample outputs:

One can list installation date too as follows:
rpm -qa —qf ‘(%): %-%\n
Sample outputs:

Getting info about specific packages

You can display more information about package using the following command:
# rpm -qi iptables
Sample outputs:

List all files installed by the RPM package

You can list package files using the following command:
# rpm -ql iptables
Sample outputs:

Feel free to add pager such as less or more to display output one screen at a time:
# rpm -qa | less
# rpm -qa | more
# rpm -qa | grep ‘something’
# rpm -ql iptables | more
Want to find out the installation date of a specific package, for example nginx, run:

List installed RPM packages using yum or dnf on Linux

Count all installed RPM packages using yum/dnf in Linux

Pass the yum command output to the wc command to count installed packages on CentOS or RHEL or SUSE:
# yum list installed | wc -l
# dnf list installed | wc -l

List all installed packages in RHEL, CentOS, Oracle and Fedora Linux

Another option is to type the following rpmquery command. However, first install dnf-utils/yum-utils package:
# dnf install dnf-utils ## Fedora latest or CentOS/RHEL 8x. — ##
# yum install yum-utils ## CentOS/RHEL 6.x/7.x — ##
Next, type the following command:
# repoquery -a —installed
# repoquery -a —installed | grep httpd
# repoquery -a —installed | more

It is also possible to list installed packages from a particular repo such as epel repo on CentOS/RHEL 7 or ELEP repo on RHEL 8 or EPEL repo on CentOS 8. First, get the repo id, run:
# yum repolist
Sample outputs:

Another example:
$ dpkg -s sudo
Sample outputs:

Use file /var/lib/dpkg/available to find out all package names available to you. Or you can use following command (list all packages in /var/lib/dpkg/status):
$ dpkg-query -l
You can also try to match package name using wild cards:
$ dpkg-query -l ‘libc6*’
Once you’ve found package name, use the following command to get exact status (whether it is installed or not):
$ dpkg-query -W -f=’$ $\n’ apache-perl
Sample outputs:

Red Hat Enterprise / Fedora Linux / Suse Linux / Cent OS

Under Red Hat/Fedora/CentOS/Suse Linux use the rpm command:
$ rpm -qa | grep For example find out package mutt installed or not:
$ rpm -qa | grep mutt
Output:

If you do not see or get any outputs (package name along with version), it means the package is not installed at all. You can display or list all installed packages with the following command:
$ rpm -qa
$ rpm -qa | less
You can conditionally do something if a rpm command succeeded or failed to find package using bash shell if command:

On a CentOS/RHEL version 6.x/7.x and above use the following yum command to tell whether a package named htop is installed:
$ yum list installed
$ yum list installed htop
Sample outputs:

If you are using Fedora Linux, try the following dnf command:
$ dnf list installed
$ dnf list installed htop

This is my first massage over here& i hope i will get full support.

How to open usermap.cfg file on NetApp server?- As i have to check whether unix user login is mapped correctly with Windows login.

As the main problem which few of the users are having is as below —

They are NOT able to map from Windows any network
drive (unix accounts) due to they have not access to their share drive.

It ask me for login and password, BUT earliear it never asked me for my windows login and password . It’s been working till the end of the year 2006.

Please suggest solutions—–

Many thanks in Advance

just a small addition –

on Gentoo Linux just do a:

or
cat /var/lib/portage/world

on CentOS or other “yum”-based systems:

yum list installed

how to see the programs and features in redhat linux (e.g– in windows we can check the same through control panel–progrmas)

@john: On RedHat – which is a rpm package management based distribution – you should can use i.e.:

to list all installed packages or

to get out details about the installed package.

how do i verify packages that are installed without using rpm, i mean recently i installed squid using make, make all, configure configure-install

after this, how do I check this package is installed?

…this is not possible as installing “by hand” (make install) has nothing to do with a “package” nor package management.

To find out if i.e. squid was installed just try to locate the squid binary by where, locate or find, even if you build and install software from sources by make.

If you use a port management system from i.e. pkgsrc, getoo portage or even FreeBSD the port management counts each modified and installed file of a port to make it possible to see which file belongs to which port (package) or which are installed etc.

this might be another story.

Thank you very much, I have another issue, I have Installed texlive but I still get an error message in my crm ” pdf latex not installed”, so do you know how check if any software is installed or not ? It’s different from packages, isn’t it ?

If you have a list of packages you want to query, it’s much easier to just list them instead of using grep:

rpm -q automake libtool flex bison pkgconfig gcc-c++ boost-devel libevent-devel

Why such a complicated command for rpm-based systems? On my machine (Fedora 20), I can just run rpm -q $, and it’s *much* faster since it doesn’t need to list every package on the system and then grep through it:

[blong@blong-desktop tmp]$ rpm -q vala; echo $?
vala-0.22.1-1.fc20.x86_64
0
[blong@blong-desktop tmp]$ rpm -q missing-package; echo $?
package missing-package is not installed
1

Is this a new feature?

In Debian based distros like Ubuntu, you can find out if a package is installed with:

apacheInstalled=$(dpkg -s apache2 | grep ‘Status: install ok installed’| wc -l)
#change apache2 to the package you are checking for. returns 1 if installed, 0 otherwise.
#script does not have to be running as root… but to change installed stuff… it would.

How to List Installed Packages on Ubuntu and Debian-based Linux Distributions

Last updated August 23, 2021 By Abhishek Prakash 20 Comments

So you installed Ubuntu and started using it extensively. Somewhere down the line, you are bound to lose the track of the software that you had installed over the time .

That’s perfectly normal. No one expects you to remember all the packages installed on your system. But the question arises, how to know what packages have been installed? How to see the installed packages?

To list all the installed packages using apt:

apt list –installed

Read the rest of the tutorial to know more about other ways and some more tips to fine tune your search for installed packages.

List installed packages in Ubuntu and Debian

If you use apt command extensively, you would probably expect a command like apt list installed packages. You are not entirely wrong here.

While apt-get command doesn’t have a straightforward option like apt-get list installed packages, apt has a command for this.

This will list all the packages that have been installed using apt. It will also list the packages that were installed as a dependency. Which means that not only you’ll have the applications you installed, you’ll also have a huge list of libraries and other packages that you didn’t install directly.

Check whether a specific package is installed in Ubuntu

Since the list of installed packages is a huge one, it would be a better idea to use grep and filter the output for a certain package.

A better way is to use this command:

Both q options are for quiet mode. And this way, it only looks for programs that are installed.

Note that the above method also lists the applications installed with .deb files. That’s cool, isn’t it?

Other ways to check installed packages in Ubuntu/Debian

If you have read my apt vs apt-get comparison article, you probably already know that both apt and apt-get basically use dpkg . This means you can use dpkg command to list all the installed packages in Debian.

You can filter the output with grep again to search for a specific package.

So far, you have dealt with applications installed with Debian’s package manager. What about Snap and Flatpak applications? How to list them because they are not accessible with apt and dpkg?

To show all the Snap packages installed on your system, use this command:

Snap list also indicates which applications are from a verified publisher with a green tick.

To list all the Flatpak packages installed on your system, use this:

Let me summarize it for you.

To list packages using apt command:

apt list –installed

To list packages using dpkg command:

dpkg -query -l

To list Snap packages installed on your system:

snap list

To list Flatpak packages installed on your system:

flatpak list

List the recently installed packages

So far you saw the list of installed packages in alphabetical order. What if you want to see the packages that have been installed recently?

Thankfully, a Linux system keeps a log of everything that happens in your system. You can refer to the logs to see the recently installed packages.

There are a couple of ways to do this. You can either use the dpkg command’s log or the apt command’s log.

You’ll have to use grep command to filter the result to list the installed packages only.

This will list all the packages including the dependencies that were installed recently on your system along with the time of installation.

You can also use the history of apt command. This will show only the programs that you installed using apt command. It won’t show the dependencies installed with it, though the details are present in the logs. Sometimes, you just want to see that, right?

The output should be something like this:

The history log of apt is quite useful because it shows the time when the apt command was run, the user who ran the command and the packages that were installed by a command.

Bonus Tip: Show installed applications in Software Center

If you are not comfortable with the terminal and the commands, you still has a way to see the applications installed on your system.

You can open the Software Center and click on the Installed tab. You’ll see the list of applications that have been installed on your system.

It won’t show the libraries and other command line stuff though but perhaps you don’t want to see that as you are more GUI centric. Otherwise, you can always use the Synaptic Package Manager.

That’s it

I hope this quick little tutorial helped you to see the list of installed packages on Ubuntu and Debian based distributions.
