The \u201capt-get<\/strong>\u201d command manages the packages in Ubuntu by retrieving information about those packages. The \u201capt-get\u201d simplifies the installation, handling, deletion, and overall management of libraries and packages. This article discusses the apt-get command to install packages in Ubuntu.<\/p>\n

How to Use Apt-Get to Install Programs in Ubuntu From the Terminal?<\/strong><\/h2>\n

The apt-get is a simplified way to download and install packages or programs from official repositories with ease. To install programs in Ubuntu using the \u201capt-get\u201d command, follow the steps below.<\/p>\n

Step 1: Open Terminal<\/strong><\/h3>\n

Start the terminal by clicking on the \u201cShow Applications\u201d icon at the bottom left of the home screen:<\/p>\n

<\/p>\n

The Applications Menu Open and you will see the Search Bar. Click on it and type the application you want to search for. In our case, we will search for \u201cTerminal\u201d:<\/p>\n

<\/p>\n

Click on the Terminal to Open it:<\/p>\n

<\/p>\n

The shortcut key \u201cctrl+alt+t<\/strong>\u201d can also be utilized to open the Terminal:<\/p>\n

<\/p>\n

Step 2: Update Existing Packages<\/strong><\/h3>\n

Once the Terminal is opened, update the existing packages before installing a new package using the command:<\/p>\n

sudo<\/span> apt-get update<\/span><\/div><\/div>\n

This will update the existing Ubuntu packages:<\/p>\n

<\/p>\n

Upgrade the packages that are updated using the command:<\/p>\n

sudo<\/span> apt-get upgrade<\/span><\/div><\/div>\n

<\/p>\n

Step 3: Search for Packages<\/strong><\/h3>\n

The \u201capt-cache\u201d command searches for packages. To use the \u201capt-cache\u201d command, the search command is used with it as well as the package name to be searched:<\/p>\n

sudo<\/span> apt-cache search<\/span> <<\/span>package-name><\/span><\/div><\/div>\n

In our case, to search for the \u201cblender\u201d application, the \u201capt search\u201d command will be:<\/p>\n

sudo<\/span> apt-cache search<\/span> blender<\/div><\/div>\n

The packages containing the keyword \u201cblender\u201d will be listed in the Terminal:<\/p>\n

<\/p>\n

Step 4: Install the Package using Apt-Get<\/strong><\/h3>\n

The Packages in Ubuntu can be installed using the \u201capt-get\u201d command with \u201cinstall\u201d followed by the package name to be installed. Once the desired package is searched using the \u201capt-cache search\u201d command, the package can be installed using the command:<\/p>\n

sudo<\/span> apt-get install<\/span> <<\/span>package-name><\/span><\/div><\/div>\n

In our case, we previously searched for the \u201cblender\u201d package and among those packages to download and install the \u201cblender\u201d package, the command used will be:<\/p>\n

sudo<\/span> apt-get install<\/span> blender<\/div><\/div>\n

The Blender package will start downloading, wait for the completion:<\/p>\n

<\/p>\n

Step 5: Verify Package Installation<\/strong><\/h3>\n

The packages installed can be verified using the \u201cdpkg\u201d command in Ubuntu. To display all the packages installed in Ubuntu, use the command:<\/p>\n

dpkg<\/span> -l<\/span><\/div><\/div>\n

All the packages will be listed in the Terminal:<\/p>\n

<\/p>\n

The \u201cdpkg\u201d command with \u201c–get-selections\u201d is also a useful way to list all the installed packages in Ubuntu using the command:<\/p>\n

dpkg<\/span> --get-selections<\/span><\/div><\/div>\n

All the Installed packages will be listed:<\/p>\n

<\/p>\n

You can also filter for a specific package using the \u201cgrep\u201d command along with the \u201cdpkg\u201d command. To find a specific installed package, the command used is:<\/p>\n

dpkg<\/span> --get-selections<\/span> |<\/span> grep<\/span> <<\/span>package-name><\/span><\/div><\/div>\n

In our case, as we installed \u201cblender\u201d previously, we will use the \u201cgrep\u201d command to search for the blender packages:<\/p>\n

dpkg<\/span> --get-selections<\/span> |<\/span> grep<\/span> blender<\/div><\/div>\n

The blender packages installed will be returned to the terminal:<\/p>\n

<\/p>\n

Thus the packages are installed. You can also verify by launching the application either by searching for the application through the GUI or opening it directly from the terminal using the name of the application. In our case, we will type \u201cblender\u201d in the terminal and hit \u201cEnter\u201d to launch the application:<\/p>\n

<\/p>\n

If the application launches it verifies the installation of the packages:<\/p>\n

<\/p>\n

Bonus Step 1: Uninstalling Package<\/strong><\/h2>\n

The packages installed can also be uninstalled when required using the terminal. When the package is no longer required, it can be uninstalled:<\/p>\n

sudo<\/span> apt-get remove<\/span> <<\/span>package-name><\/span><\/div><\/div>\n

In our case, to remove or uninstall Blender from our system, we will use the command:<\/p>\n

sudo<\/span> apt-get remove<\/span> blender<\/div><\/div>\n

This will uninstall the blender packages and ask for confirmation. Enter \u201cY\u201d to continue uninstalling:<\/p>\n

<\/p>\n

Bonus Step 2: Cleaning System after Uninstalling<\/strong><\/h2>\n

It is good to clean up the Ubuntu system ensuring no files are left behind after uninstalling a package using the command:<\/p>\n

sudo<\/span> apt-get autoclean<\/span><\/div><\/div>\n

This will clean the system and if any packages are left after deleting or uninstalling, will be removed:<\/p>\n

<\/p>\n

Conclusion<\/strong><\/h2>\n

The apt-get command can be used to search for a specific package and then install those packages using the install command with \u201capt-get\u201d. The \u201capt-get\u201d command also removes or uninstalls the packages from the Ubuntu system as well as auto cleans after removing packages.
