Unix/Linux online terminals or emulators to practise various Linux commands & testing scripts on command base online Virtual Linux machines such as Ubuntu, Centos or Buildroot. Use them without installing OS physically on Windows, MacOS, Android or Linux PC; just what you need is a browser.
What are Virtual terminals in Linux?
Virtual Linux Terminal is also known as Virtual console (VC) is not a thing we are not acquainted of if you are Linux user, except using it online, that could be a new thing. Each and every Linux operating system comes with Virtual Terminal that we use to operate and manage different services and apps on them. It allows the keyboard to input commands and computer displays for showing output; most of the Unix-like operating systems use Virtual Terminals such as BSD, Linux, illumos and UnixWare. For example, if you are using Ubuntu Linux graphical version and want to access full-screen terminal then simply press Ctrl+Alt+F1 and to come back to graphical session use Ctrl+Alt+F7.
Thus, what is the difference between that and online Linux terminal; the answer is not much except, the online is one is running on some remote server and available for you using the internet connection, remotely but with some limitations.
Now, Why we use Virtual Linux terminal online? Suppose you are a student or some beginner in software developing who is eager to learn Linux commands, so, it is hard to install virtual machines on every local system to practise Linux commands; in that situation, you can use Linux online terminals for testing shell scripts, commands, or connecting some remote Linux server using SSH.
Although, with Windows 10’s WSL (Windows Subsystem for Linux) you don’t need Virtual machines to use Linux OS or terminal, yet, online Linux terminal simulators are the quickest methods where the only thing we need is the browser. It could be Google Chrome, Microsoft Edge, Mozilla Firefox, Opera or any other. It doesn’t matter you are using Windows 10/8/7, Linux, MacOS or Android, it works everywhere.
Note: All virtual terminals mentioned here do not offer full-screen mode.
In this article, we will give answers of questions that arise after understanding the above paragraphs such as how do I run a Linux command Online? Which online Linux shell available to use free of cost? and more…
Best online Linux terminals with root access
All below given online Linux terminals are free to use with root access where one can practise Linux commands without paying any dime, however, some may require a free registration process. Moreover, these are randomly listed and not on the basis of their features and capabilities.
Webminal- Online Linux/bash terminal
Webminal is really a wonderful Virtual Linux Terminal online for practising various Linux commands. It is running on the remote server of the provider as a container or virtual machine. To use the Webminal, the user first has to create a free account with them and then this free online Linux learning platform is available in your browser.
We can use it not to only practise Linux commands but also for creating bash scripts, getting familiar with MySQL tables and to learn programming languages Python, C, Ruby, Java, Rust using Webminal IDE. However, the Webminal IDE online is free for a month after that a user needs to pay $2 per month which is an exiguous amount.
The online Linux terminal it provides is with root access with 100M storage space, ability to create files up to 1000, 1MB is the maximum size of file user can create here; a user can run multiple terminals for up to 10 processes only. You can use both keyboard and mouse. The login and user ID for root on Webmail will be the same that a user has created during sign up of an account.
Link to Offical Website to use Webminal
It is one of the best online Linux Terminal becuase it provides all in one Virtual Web app to operate different Linux consols and cross-platform cloud IDEs.
Codeanywhere provides a full-fledged online Linux virtual machine running in containers such as Ubuntu and CentOS. Root access is there along with full control to destroy the virtual machine and its configuration. It gives a real feel of using Linux OS on Virtual terminal. It has the ability to connect Dropbox, Google drive, FTP server, Amazon S3, Bitbucket OneDrive, DigitalOcean to create Droplets directly from Codeanywhere terminal and more. You can create containers of Ubuntu and CentOS blank or with .NetCore/C++.
The only thing is Codeanywhere is not a completely free online Terminal, it provides 7 days free trial and after that basic plan charges $3/per month with some feature limitations, anyway the price is quite low and not a big deal if you really want to learn Linux commands and practise it from anywhere just using the internet connection and browser.
