Some most essential Application for Linux:

Application software is distinct from system software, which refers to the software that keeps the systems running, such as the operating system, computational science software, game engines, industrial automation, and software as a service application. In this article, we will elaborate on Most Essential Applications for Linux Operating systems.

1.Thunderbird:

Thunderbird is Mozilla’s email client. While it technically is still maintained and various bug fixes continue to be released, there hasn’t been a significant update in quite some time. But really, how “updated” does an email client need to be? Can it send and receive an email? Yes? Okay, then it’s purpose is fulfilled. ​

2.Geary:

The default email client comes with the GNOME 3 Desktop environment. Distros that use the pure GNOME 3 desktop environment (such as Fedora) will likely have this installed by default.

3.Evolution:

It also functions as a complete personal information management suite, including useful tools such as Calendar. Its functionality is very similar to Microsoft Outlook, and it can be connected to a Microsoft Exchange server if desired.

4.Firefox or Chrome:

You know what these are. But rather than choose one over the other, you could take the middle route and install both! Some Firefox add-ons are not in Chrome, and vice-versa. And maybe you want to keep individual bookmarks and add-ons separate between two browsers, i.e., one for work and one for play.

5.LibreOffice:

Linux replacement for Microsoft Office can do everything Microsoft Office can do, and you don’t have to pay hundreds of dollars for it. Most distros include LibreOffice by default.

6.gscan2pdf:

Simple app for scanning documents to the PDF format, which students may find useful, but is also helpful when you need to upload official documents you may have.

7.Kee-Pass:

If you are getting to the point where you have so many accounts with so many different passwords, and you just can’t mentally keep track of them all anymore, then Kee-Pass will be immensely useful for you. It’s a password manager that will store all of your usernames and passwords in an encrypted database. Just make sure you don’t forget the Kee-Pass password!

8.VirtualBox:

If you want to experiment with different Linux distros or different OS in general, you can install VirtualBox and run a virtual machine inside of your actual machine. Performance won’t be quite as good as a native OS (Operating System) installation, but if your system has enough horsepower, you’ll notice minimal performance degradation.

9.WizNote:

A Linux alternative to Evernote, OneNote, and other similar note-taking applications.

10.gdeb:

If you are running a Debian-based system (such as Ubuntu or Mint), occasionally, you won’t be able to find specific software in the official repositories. You’ll have to install a .deb package (or install in PPA if applicable).gdebi allows you to execute .deb packages, which will install that particular software (you can think of .deb files as the Ubuntu/Mint/Debian equivalent to .exe files in Windows).

11.XDM or uGet:

Download managers. I personally don’t like download managers (except for Down them all for Firefox, but that’s only used in some instances), but some people do. In my opinion, browsers’ built-in download managers are sufficient. It’s your system, installs whatever you like.

12.UFW/GUFW:

The Linux firewall. GUFW is the GUI version of UFW, which is typically run in a command-line terminal. Super simple to configure and enable/disable, definitely less of a headache than Windows Firewall.

13.Gimp:

Linux’s answer to Photoshop. Probably the most popular image editor on Linux.

14.Pinta:

Suppose you don’t need all the bells and whistles of GIMP. Pinta is a Linux alternative to MS Paint.

15.BleachBit:

Linux equivalent to Windows CCleaner has some extra features such as secure file shredding. Linux systems do not typically need much cleaning in the first place, but when they do, BleachBit is a handy tool to have.

16.SoundCloud:

Linux is An unofficial Linux client for the Slack messaging program (not to be confused with the Slackware Linux distro). If your organization communicates primarily on Slack, you’ll want this. Slack itself also has a Linux application in Beta that’s currently available for Ubuntu and Fedora.

17.Synaptic:

A package manager is installed by default on many distros, but not all. It provides an alternative way to install and remove packages. Many advanced users prefer it over using the included Software Center applications on many distros.

18.DropBox:

Cloud storage and they have an official native Linux client! Something that Google Drive has yet to deliver on.

19.VLC:

The video player that will play anything, no questions asked. If you’re tired of always having to find codecs on Windows, VLC solves that problem for you. It can also play audio files.

20.Unity Tweak Tool:

For Ubuntu systems, some advanced configuration options are not included in a GUI menu by default and have to be done via the command line terminal. Unity Tweak Tool provides a GUI for these advanced configurations, most commonly for GTK and Icon themes. There’s also a GNOME Tweak Tool for GNOME desktops.

21.Sublime:

A beautiful text editor is a favorite among many developers. It’s free to try indefinitely, $70 to buy the license, a rarity for Linux applications as the overwhelming majority are free.

22.Atom:

Another beautiful text editor, without the $70 price tag

23.Notepadqq:

If you’re a fan of Notepad++ on Windows, you’ll be glad to know that the developer has a Linux port called notepadqq. It may not be in your distro’s official repositories, but you can always add a PPA or install the package manually.

24.Brackets:

Another text editor. They all do the same thing; they just have different sets of bells and whistles.

25.Cheese:

Linux’s webcam application. Some video chat apps may require it as a dependency. ​

26.Gparted:

The GUI version of Linux’s command-line parted utility. We used for disk management (i.e., formatting and partitions).

27.CrashPlan:

Backup utility for Linux. Remember, if your data isn’t backed up in at least two other places, it doesn’t exist.

28.Kodi:

All in one media player, similar to VLC in terms of functionality. Also used to run Steam on Arch Linux.

29.Genymotion:

If you develop for Android, you will need something to test your code on. Genymotion is an Android emulator so that you can test your Android apps without having to actually use an Android device.

30.Tomahawk:

An all-in-one music player that allows you to connect all of your various music accounts (Spotify, YouTube, Last.fm, and more) in one seamless application.

31.GNOME System Monitor:

Part of the GNOME desktop, the system monitor, allows you to view information about your system in real-time, such as CPU usage, RAM usage, temperatures, bandwidth, storage space, and more

32.Conky:

The Linux alternative to Rainmeter on Windows. Generally used for system monitoring, conky will display lightweight “skins” on your desktop that function as persistent system monitors (whereas tools like GNOME System Monitor will open in their windows).

33.Transmission: Super primary BitTorrent client. It comes installed by default in Ubuntu.

34.BitTorrent:
One of many torrent clients is for Linux. They all do the same thing, so find one that has a UI that you like.

35.Tixati:
Another BitTorrent client. Man, there’s a ton of these. They all do the same thing, download, and upload torrents.

36.Steam:
Never fear gamers, Steam works on Linux as well as Windows; however, that doesn’t mean that every game is Linux compatible. Most (if not all) of the Valve releases are Linux compatible, so if you’re a Counter-Strike or Team Fortress player, you should be able to play on Linux (assuming your graphics drivers are set up correctly). Many games are Windows only, though, so you might have to venture outside of your comfort zone to find some new Linux compatible games. You can search the Steam Store for Linux compatible games.

37.WINE:

Stands for WINE Is Not an Emulator allows you to run Windows applications on Linux. It’s not perfect, many applications and games work flawlessly, but some just won’t no matter how hard you try. Your mileage may vary.

38.PlayOnLinux:
A helper application for WINE can make the installation of certain games much more straightforward.

39.VeraCrypt:
The continuation of the now-defunct TrueCrypt project allows you to create encrypted volumes on your system.

40.FileZilla:

A client and server version, FileZilla, is easily the best FTP client available. I’m not sure who even uses FTP anymore, but it’s there if you need it. Maybe you have 500GB of files that you need to send.

41. Pidgin: Universal chat client allows you to connect all of your various chat/IM accounts into one place (AIM, Yahoo, MSN, IRC, and more).

42.Skype:

The popular video chat application, everyone knows what Skype is. However, be cautious of installing it on your system. We suggest using whatever video chat alternatives you can find.

43.Record Desktop:
Same as above, desktop recording application.

44.Brasero:
CD/DVD burning application comes installed by default in Ubuntu. Not many people burn CDs anymore or even use ODDs at all for that matter, but if you still need to burn physical disks, Brasero will be your best bet.

45.Nmap:
Network mapping tool, allows you to view open ports and other various resources on your network, useful if you’re security-minded and you want to harden your network as much as possible.
If you have needed any kind of software you can try open-source software to download repository or RPM (Repository Package Manager) from the internet.
