Now copy mylist.txt to server named server2:
$ scp mylist.txt user@server2:

How to restore a list on server2

On server2 restore installations from the mylist.txt, run:

if you have aptitude installed, this works as a search
aptitude search ‘

that said, i prefer the solutions already listed

Alternative:
( zcat $( ls -tr /var/log/apt/history.log*.gz ) ; cat /var/log/apt/history.log ) | grep apt-get | grep install

It is not perfect but always worked fine for me.
cheers

I’m using this for years:

I’ve come across a TON of tutorials on this subject that seem to leave out the method for cleaning up the output file for parsing.

For the section:

How to save a list to a text file

The syntax is as follows on server1:

$ dpkg —get-selections | grep -v deinstall > mylist.txt

This ends up giving you a text file formatted like this:

…
tcpdump install
tdb-tools install
telnet install
time install
zlib1g:amd64 install
…

You will get gripes about “install” not being a package in APT if you skip straight to using:

sudo apt-get install -y $(

You need to get rid of all the tabs, newline chars and properly space the text of the list first. There may also be a difference in platform such as amd64 vs i386.

To do that, I’m a fan of this Perl5 one-liner:

perl -pe ‘s/\s*install\n|\:amd64/ /g’ mylist.txt > mylist.txt

This tweaks the file to look like this instead, which will actually work with that final step using «apt-get install -y» :

. tcpdump tdb-tools telnet time zlib1g .

Thanks for adding your notes. I appreciate your post.

How do I see what packages are installed on Ubuntu Linux?

I am a new Ubuntu Linux server user. My server hosted at Google cloud VM. How do I see what packages are installed on Ubuntu Linux?

Introduction: Ubuntu Linux is an open source operating system based upon the Linux kernel and GNU command line utilities. Ubuntu Linux is extremely popular among new Linux users as well as developers all around the globe. This page shows how to list all installed packages with apt command or apt-get command on Ubuntu Linux.

Tutorial details
Difficulty level	Easy
Root privileges	Yes
Requirements	Debian or Ubuntu Linux
Est. reading time	5 minutes

You need to use the apt or apt-get or dpkg command to list all installed packages on an Ubuntu Linux server from the bash shell prompt.

How do I see what packages are installed on Ubuntu Linux?

The procedure to list what packages are installed on Ubuntu:

1. Open the terminal application or log in to the remote server using ssh (e.g. ssh user @ sever-name )
2. Run command apt list —installed to list all installed packages on Ubuntu
3. To display a list of packages satisfying certain criteria such as show matching apache2 packages, run apt list apache

Let us see some examples about how to list installed packages on Ubuntu and Debian Linux operating systems.

apt list installed packages

Let us list all software packages on Ubuntu Linux available for us:
$ apt list

You might want to use the grep command/egrep command to filter out:
$ apt list | grep nginx
OR
$ apt list | more
However, you may see message on screen that read as follows:

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

To avoid this message use the dpkg command as follows:
$ dpkg —list | grep nginx
$ dpkg —list | more

List all installed packages only

The apt command displays both installed and packages available to install. What if you want to list currently installed software only? Fear not, pass the option to the apt command:
$ apt list —installed

How to list or find out if a specific package installed or not

Run package policy as follows:
$ apt list -a pkgNameHere
Is sudo package installed?
$ apt list -a sudo
Is sudo package mariadb-server?
$ apt list -a mariadb-server

Ubuntu list installed packages

It is also possible to list installed packages matching given pattern. The syntax is:
dpkg -l pattern
dpkg —list pattern
apt list pattern
apt list —installed pattern
For example:
dpkg —list ‘x*’
Sample outputs:

• ii – Indicates that package named xauth installed.
• un – Indicates that package not installed or in Unknown status.

Listing installed packages sorted by installation date and time

There is no simple command, but we can use the combination of zgrep and other commands as follows. Let us count it:

Total installed packages on nixcraft-wks01 : 6433
List them:
zgrep » installed » /var/log/dpkg.log*

Please note that zgrep will search possibly compressed files for a regular expression as those log files are compressed by system. Hence, we need to use various z commands on Linux. See “How to find out when Debian or Ubuntu package installed or updated” for more info.

Conclusion

You learned how to list both installed and uninstalled packages on an Ubuntu Linux server or desktop using the CLI method. See the following man pages using the man command:
man apt
man apt-get
man dpkg

Check and list installed packages with yum command

From the dnf/yum man page:

The list command dumps lists of packages depending on the packages’ relation to the system. A package is installed if it is present in the RPMDB, and it is available if it is not installed but it is present in a repository that DNF knows about. The list command can also limit the displayed packages according to other criteria, e.g. to only those that update an installed package. The exclude option in configuration file (.conf) might influence the result, but if the command line option –disableexcludes is used, it ensure that all installed packages will be listed.

Hence, to lists installed packages on CentOS, type the following yum command:
sudo yum list —installed
sudo yum list —installed | more
