In this article, we will look at the commands with which we will get a list of packages and find out for what purposes they are needed. How can install the packages on "server 2" after receiving a list of all the ones that are installed on "server 1"? How can use the apt command on an Ubuntu Server or Debian Server to list every package that has been installed? To view a list of every package installed on an Ubuntu or Debian Linux Server, you must use dpkg along with additional commands as follows.

Open the terminal application or log in to the remote server using ssh. You can get the following command to obtain the packages listed:

A list containing the name, the current version, and a synopsis of the goal will show up in the terminal.

The apt command displays both installed and packages available to install. Pass the option to the apt command for Ubuntu OS:

Packages with the most recent version and architecture are listed using this command.

In most cases, it is necessary to move an installed list of packages from one server to another instead of installing and configuring each one separately. Two steps must be taken in order to accomplish this:

1. The package list that the command previously generated from server #1 should be saved.

We utilize the following to generate a file containing a list of installed packages:

The "packageslist.txt" file name is an example.

2. On server #2, install the dependencies.

The file with the list of packages and versions is copied to server #2 with your ip server address. For example, for 192.168. 123.132 the command would look like this:

A command-line tool called SCP enables you to safely move files and folders between two places.

The final step is to roll the packages from the duplicated file. This is done by using the command:

Completed! The package list has now been transferred from server #1 to server #2.
