Terminal (emulator)

The terminal itself is a physical device that allows inputting and receiving information from a computer. The most important thing is that it is not necessary for the processing of instructions and data to be carried out on the terminal itself.

Certainly, in today’s world, it is common to interact with the operating system in text mode. Well, in most cases, we will not refer to this meaning of terminal. In fact, the correct term refers to the so-called terminal emulators. These allow us to use text mode within a graphical user interface. This other class of terminals are merely applications that run and give us access to a shell. In fact, they usually allow multiple shell types to be used. This is the case, for example, of Windows Terminal. By default, we will be able to manage the following: Windows PowerShell, PowerShell, Command Prompt, Azure Cloud Shell, the multiple distributions we have installed in the Linux Subsystem (WSL), etc.

On the other hand, Windows Terminal is not the only Windows terminal emulator. Indeed, there are MobaXterm, Cmder, ConEmu and others. However, in the case of Unix-based systems (Linux, *BSD, macOS), the catalog of available terminals is multiplied to infinity. In fact, each desktop environment usually offers its own (Gnome Terminal in GNOME, Konsole in KDE, iTerm in macOS…). But it is also possible to install third-party alternatives for all tastes (Terminator, Alacritty, Guake, st…).

Each terminal emulator differs by offering its own graphical interfaces, functionalities, and configuration options. For example, keyboard shortcuts, font and background customization, clipboard management, etc.

Consola [Virtual]

Console is a term that is often used inconsistently. In fact, even more so than the other terms in this list. Additionally, multiple definitions are available on the Internet. In fact, the discrepancies start even in the origin of the word. For some, the old physical console is exactly the same as a physical terminal. On the other hand, others introduce certain nuances, considering the former as a subset of the latter.

What happens when we talk about virtual console? What happens when we talk about virtual console? Many sources consider it, also, synonymous with (terminal emulator.) However, it would be more correct to refer to it as a shell session. Let’s see, let’s suppose we open a terminal emulator and start typing commands directly. In that case, we are, effectively, using a terminal and a console.

On the other hand, suppose we open two tabs in the terminal emulator, whether they are from the same shell. In that case, we are already using two consoles. It can also happen that we subdivide a tab using tools such as a multiplexer (for example, Tmux), or functions such as split table of Windows Terminal. In such a case, the number of consoles will continue to multiply, even if we are only using a single terminal.

In addition, when using a Linux system, we always have several consoles open (although not visible). We are talking about the so-called ‘TTY’, which we can access with the keyboard shortcut Ctrl + Alt + function key (one per key). Part of them will be graphic consoles. However, the others will be text consoles, each running in parallel with the others. Additionally, all of them working outside our graphical environment, so we would not be using them from terminal emulators.

Shell

We have already mentioned, when talking about terminals, several examples of different shells that can be found in Windows. As with terminals, the number of shells in Unix systems multiplies. Certainly, Bash is usually installed as the default shell. However, it is possible to change it for different ones, such as the very popular Zsh. Remember that macOS ended up adopting it as a default shell. Other options include the emerging Fish, the old Ksh and Tcsh, or minority options such as Xonsh.

The function of the shell is to interpret the commands we enter. You might think that there can’t be much difference in how some commands are interpreted. However, there are many variables to watch out for. For example, the different syntax of the scripts, or aspects such as the possibility of creating aliases and defining variables. Also, the existence of syntax highlighting or auto-completion functions. Likewise, the way in which the system output is displayed on the screen. Well, all these elements can make the user experience vary significantly depending on which shell we use.

Command interpreter (or command line)

Every shell is a command interpreter. However, not every shell is a shell. A command interpreter (also called CLI), is any software that interacts with us through the input of text commands. Some CLIs run on top of a shell and are not intended to be a way to control the operating system. Instead, they aim to be just a very specific software or online service. Examples of this can be NPM, IPython, GitHub CLI, AWS CLI or our favorite SSH client. Very well, in this way we have made clear the differences between terminal, console, shell and command line. Bye!

How to install PowerShell 7 Windows 10 with MSI file.

One of the ways to install this app is by downloading an MSI file. This type of file is similar to executables. Consequently, it is possible to install the applications through a graphical interface. With this intention, please refer to this link. Please select the version corresponding to the architecture of the pc.

Once you have downloaded the file, please install it in a regular way.

How to install PowerShell 7 Windows 10 with CMD

Now, Microsoft has developed a script that can be invoked from PowerShell to execute the installation. With this intention, press the Win+X combination to launch the PowerShell with administrator privileges.

Once there, please type the following text.

 iex "& { $(irm https://aka.ms/install-powershell.ps1) } -UseMSI" 

After pressing Enter, the download of the MSI will start. Once the download is complete, the installation wizard will start. Please press Next to continue the process.

After choosing the destination directory, it is time to customize some installation options:

• Add PowerShell to Path Environment Variable: This makes it possible to call PowerShell from any other shell or terminal.
• Register Windows Event Logging Manifest: This option allows events to be logged from one PowerShell instance
• Enable PowerShell Remoting: This option enables the ability to execute commands in PowerShell remotely.
• Add ‘Open here’ Context Menus to Explorer.

After confirming the installation, please wait a few seconds while the installer completes the task. Finally, check the option to launch the PowerShell. Press finish seeing the new terminal in action.

From this point on, just press the Windows button to find the new PowerShell.

Conclusion

In the final analysis, we looked at how to install PowerShell 7.0 in Windows 10. In addition, the previous version will remain installed. So it’s possible to use both versions without problems. All right, I hope you enjoyed this post. Before I say goodbye, I invite you to check our tutorial on how to be a Windows Insider. See you soon!

However, Windows 10 by default is not compatible with this programming language, so to run applications programmed with it, we have to install all the libraries and dependencies of Python in the system and configure them, a task that for many people can become complicated.

Installing Python 3

For this reason, today we will learn how to install Python 3 in Windows 10. In the first place, we need to download it, Once on the page, we choose Download Python 3.7.4 (or the number that is when we visit it, as long as it is 3)

Once the download is finished, we have to proceed to execute it as the Administrator user. A window will appear, select both options at the bottom of it; install launcher for all users (to grant access for all users) and Add Python 3.7 PATH (add the path of the interpreter to the PATH variable). This second option is imperative to select, inasmuch as allow run python.exe from anywhere on the command line (otherwise, we would have to always put the absolute path).

Then, press Next to start the installation.

A couple of minutes later, our installation will be finished. If a warning message appears, asking for a disabling path length limit, then we need to approve it.

Testing Python 3 operation

To start python, we have to press Windows + R keys, to invocate CMD box. Once there, type python. Thereupon we will have a console with Python interpreter and we could make operations like additions, subtraction and more.

To go out of Python, type

exit()

Postscript. Installing Python 3 from Windows Store

It is quite known that most of the users in Windows 10 would like to install programs, just by clicking on some buttons. As a matter of fact, Windows Store is full of programs (free or paid) ready to be downloaded and installed by users. With this in mind, Python Software Foundation has to dabble in Windows Store, offer Python 3 to those users who own at least Windows 10 version 17763.0 or high. However, it does not come with absolutely all the components that are included in the complete conventional installer. Inasmuch as, developers are still working to be able to bring all these components to this installer. In addition, they also warn that there may be a problem and some applications may not work properly. Although this may be true, this option is very interesting and for sure will be improved in the future.

Now, we have installed Python 3 in Windows 10, and we can start to use it. Please visit our tutorial about the backup windows registry.

Learning Linux console can be tricky and in many cases, you may need help. It’s the best to have a friend physically present beside you to help you out, but that’s not possible all the time. Don’t worry; there’s a way that you can use to share your console with others and get direct help.

Let’s meet Teleconsole!

Teleconsole is a command-line based tool that allows sharing your console with others. It also offers security with the console sharing like SSH or HTTPS connection.

Run the following command for installing the “snap” package of Teleconsole. Snap feature comes up built-in in most of the modern day Linux distros. If your system doesn’t have it, you can simply install it by following the simple guide from official snap documentation.

sudo snap install teleconsole --classic

If your system doesn’t support “snap” feature, you don’t have to panic. There’s also a way of installing the software as a script. At first, install Curl in your system.

Note that this tutorial is to install Curl from source. Then, run the following command:

curl https://www.teleconsole.com/get.sh | sh

Sharing the terminal

Now, the time has come for sharing the console with your friends! Launch the tool:

teleconsole

After executing the command, you’ll be given two things – a Teleconsole ID and a link. One can use both for connecting with a remote console over the internet.

If you’re not comfortable sharing your link, you can send the ID. For connecting to a remote ID via Teleconsole, run this command:

teleconsole join <ID>

If you’re in need of any further help on the tool, simply run this command:

teleconsole --help
