How to Access Installed Apps in Ubuntu

0

From where a Ubuntu user can access installed software. After installing app manually or by using terminal in Ubuntu, it gets disappeared. What is the location of all the installed programs in Ubuntu? Is there a utility from which we can browse, access and run installed applications in Ubuntu? Microsoft Windows has got the ‘Start’ menu to use installed programs. MAC has got ‘Applications’ folder for installed apps. What have we got in Ubuntu for this?

Ubuntu also has got Applications folder to browse installed apps. Location for that folder is:

/usr/share/applications/

You can access that location by clicking at ‘Files‘ icon. Once you are at that location hit / key from keyboard, type usr, the rest of address as mentioned above and hit enter. This is the location to access any installed application in Ubuntu. You can save that location to access it later quickly.

Ubuntu Applications

Save this location in side dock panel of Ubuntu in Bookmarks. Press Ctrl+D to bookmark location of Applications and ‘Applications’ will be available under Bookmarks when you click Files icon.

To find any installed application, you can also search it by name. Click at the first icon ‘Dash Home’ at the left panel from desktop. It will bring up the search panel. Type name of application you are looking for and the results will show you applications relevant to that.

You can also open ‘Ubuntu Software Center’ or ‘Software and Updates’ by going to ‘Dash Home’ and searching the term ‘software’. Click at the first icon in left side panel. That will bring up search. Type ‘software’ and you will see ‘Software Center’ and ‘Software and Updates’. Click any of that to bring up software resources in Ubuntu. From there you can filter installed software.

Following command will give you a list of packages installed locally.

dpkg --get-selections | grep -v deinstall

If you also want to save that list of installed packages on your desktop, use following command in terminal.

dpkg --get-selections | grep -v deinstall > ~/Desktop/packages

you don’t need to run above commands as the superuser, so no sudo necessary.

Following command from terminal, will generate a list of installed applications in txt file in home folder.

sudo dpkg --get-selections > installed-applications.txt

Following command will install a backup tool that can generate and save installed apps list.

sudo add-apt-repository ppa:webupd8team/mintbackup && sudo apt-get update
sudo apt-get install mintbackup

Backup Tool

Following command will give you a list of manually installed packages in Ubuntu.

apt-mark showmanual

Create a backup of packages currently installed by using following command.

dpkg --get-selections > list.txt

You can also restore installations by using following command (on another system).

dpkg --clear-selections
sudo dpkg --set-selections < list.txt

To list all packages intentionally installed by apt commands, use following command.

( zcat $( ls -tr /var/log/apt/history.log*.gz ) ; cat /var/log/apt/history.log ) | egrep '^(Start-Date:|Commandline:)' | grep -v aptdaemon | egrep '^Commandline:'

To list all installed packages, and get result in 1.txt file in home folder, use any one of following command.

dpkg -l |awk '/^[hi]i/{print $2}' > 1.txt

or

aptitude search -F '%p' '~i' > 1.txt

or

dpkg --get-selections > 1.txt

You can also use Aptik that is a tool to backup and restore software, sources and related stuff.

Also if you really want that menu thing that shows all the installed apps to access from, ‘Classic Menu Indicator‘ is the way to go. It will bring back the start like button on the notification area of the top panel and brings back GNOME Classic Menu experience in Ubuntu, from where you can select programs to run.

Classic Start Menu in Ubuntu

My screenshot above is not clear because menu disappeared while taking screenshot. So below is the official screenshot of menu.

Classic Menu Indicator

To install the menu, open Terminal and use these commands.

sudo apt-add-repository ppa:diesch/testing
sudo apt-get update
sudo apt-get install classicmenu-indicator

You may have to restart the system for changes to take effect.

There are other indicators available. Some are really really useful. Check these out here.
