Текстовый редактор windows powershell

Did you run a script that read a text file and discover that the file had several wrong entries? A PowerShell text editor may come in handy in such situations. You wouldn’t need to fire up an external editor. Instead, you can edit the file without leaving PowerShell. How cool is that?

Keep reading, and you will learn how to install and use three text editors (Nano, Vim, and Emacs) to edit your text files within PowerShell. This tutorial will also cover the benefits of each to help you choose which one is ideal for you.

Let’s get started!

Prerequisites

This tutorial will be a hands-on demonstration. If you’d like to follow along, be sure you have the following:

  • A computer running on Windows 7 or higher. The examples in this tutorial will use Windows 10 version 21H1.
  • Windows PowerShell v3+ or PowerShell Core v6+. This tutorial will use Windows PowerShell version 5.1.
  • The latest version of Chocolatey (v0.11.2 as of the writing of this tutorial).

Using Nano as a PowerShell Text Editor

If you are new to terminal-based text editors or only need to make a quick edit to a file, Nano is ideal for you. Nano is lightweight, intuitive, and more suited for light text editing tasks compared to the other more advanced editors in this tutorial.

Installing Nano

To install Nano, follow the steps below.

1. Open PowerShell as an Administrator.

2. In PowerShell, execute the following choco install command to install the Nano text editor. The (-y) switch will bypass the confirmation prompt and proceed with installing the package.

The installation process would look similar to the screenshot below. As you can see, in this example, the Nano installation was successful.

3. After installing Nano, run the following command to verify the installation was successful and display the current version.

As you can see below, the command was successful and displayed the Nano version on your computer.

Editing and Saving a File

Now that you have Nano installed, it’s time to take it for a spin!

1. To create a new file or open an existing one, run the nano command and follow it with the filename to create or open. For the examples in this tutorial, you will be creating and editing a Windows PowerShell script, which uses the .ps1 file extension. The command below will create a new file called myPowerShellScript.ps1 on the current directory.

nano myPowerShellScript.ps1

The Nano text editor will open within PowerShell. As you can see on the image below, near the bottom says [New File], indicating the Nano has opened a new empty file.

To view all available shortcut commands, press CTRL+G on your keyboard to display the help documentation. Commands that start with ^ means that you have to press the CTRL key. On the other hand, if the command starts with M, you need to press the ALT key.

2. Next, start writing your script using the arrow keys on your keyboard to move the cursor. For example, type in the Windows PowerShell command Write-Host "Hello World!" as shown in the following image. When executed, this command will print out the text “Hello World!” to the console.

Notice that once you modify the file’s content, the word Modified appears on the top-right corner of the editor. After editing, press CTRL+O to tell Nano that you want to save the file.

4. Finally, to exit Nano, press CTRL+X.

If you try to exit the editor while there are pending changes, Nano will ask you to save or ignore the changes. If you choose to save, press Y and specify the filename to write as you did in step 3. Otherwise, press N to discard the changes.

5. Now run your script by executing the following command. The following command assumes your file is in the C:\ folder.

& C:\myPowerShellScript.ps1

The script will print the message ‘Hello World!’ to the terminal, as shown in the following image.

Searching and Replacing Text

Now that you know how to edit and save a file, it’s time to learn to do something slightly more advanced: searching for and replacing strings!

To search for a string, follow these steps.

1. First, open the text file in the Nano editor, if not open yet.

2. Once you’ve opened the text file, press CTRL+W on your keyboard to invoke the Where Is command.

3. Next, type the string to search for next to the Search prompt and press Enter. The example below will search for the word Hello.

3. Lastly, choose to replace only the current instance or all instances of the matching word in the file. The choices are:

  • To replace the single instance, press Y.
  • To replace all instances, press A.
  • To skip this instance, press N.
  • To cancel the replace operation, press CTRL+C.

In this example, press Y to replace the current instance.

Using Vim as a PowerShell Text Editor

Vim offers more features than Nano, such as session recovery, syntax coloring, window splitting, and auto-completion. Nano is meant for quick file edits, while Vim is also a lightweight alternative to an IDE.

But, the extra features Vim offers come at the cost of a steeper learning curve. Don’t get discouraged, though. Vim is an excellent editor to learn.

Installing Vim

Now it’s time to get started by installing Vim.

1. Open PowerShell as an Administrator.

2. In the PowerShell terminal, execute the following command to install the Vim editor.

3, To verify the Vim version, run the following command. vim --v

 Verifying the Vim version

Verifying the Vim version

Editing and Saving a File

Now that you have Vim installed, it’s time to get your hands dirty and learn to edit a file. Before you go any further, you should know that there are different modes in Vim. Each mode behaves differently and affects which actions you can do inside the editor.

The three commonly-used modes are:

  • Normal – The default mode as soon as you open Vim. This mode allows you to navigate the text file but not add new texts.
  • Insert – This mode is where Vim allows you to edit the file. To enter this mode, press i (case insensitive) on the keyboard. To exit and go back to the normal mode, press ESC.
  • Command – In this mode, Vim lets you invoke commands such as save the file, quit Vim, or view the help document, among others.

Moving on to editing a file in Vim, follow the steps below.

1. To open a file in Vim, run the vim command followed by the filename to open. The command below opens the myPowerShellScript.ps1 file.

vim myPowerShellScript.ps1

The vim text editor will open, as displayed in the following image. Note that the PowerShell command ‘Write-Host’ and the message ‘Hello World!’ display in different colors, as Vim supports syntax coloring.

The Vim opening view in normal mode

If you need to view the Vim help document, type :h and press Enter. Pressing the : character while in normal mode switches Vim to command mode, while h means to open the help file. To exit the help document, type :q and press Enter to return to normal mode.

Next, enter the insert mode by pressing i. As you enter the insert mode, the text -- INSERT -- appears at the bottom of the editor, as shown in the following image.

Vim in insert mode

3. Now that you are in insert mode edit the file as you wish. The arrow keys will let you move the cursor inside the editor.

4. After editing, press Esc to return to normal mode.

5. Type the command :wq and press Enter to save and close the file. The command w saves the files while q exits Vim.

Saving the file and existing Vim

Searching and Replacing Text

Follow the steps below to search for strings in Vim.

1. Open the file you want to edit in Vim.

2. On the Vim editor, to search for a string, run the command below, where <string> is the string you want to search.

For example, to search for the word Hello, type:

Vim will highlight the matching words, as shown in the following image.

To iterate through multiple instances of the matching texts, press n to move to the next occurrence or the N key for the previous occurrence.

Vim highlighting the matching words

3. Lastly, to replace every instance of a string in the entire file, run the command below, where <old> is the text to replace and <new> is the replacement text.

For example, the command below will replace the word Hello with the word Goodbye.

Using Emacs as a PowerShell Text Editor

Like Vim, Emacs offers more features than Nano. Moreover, Emacs is also an Integrated Development Environment (IDE). Some of Emacs’ features include syntax coloring, editing multiple files simultaneously, and auto-indentation.

Another benefit of Emacs over the other editors in this tutorial is Emacs is modeless. Emacs is also fully customizable. If there is something that Emacs does not offer, you can add support for it yourself using Emacs Lisp.

Installing Emacs

Follow the steps below to install Emacs.

1. Open PowerShell as an Administrator, if you haven’t yet.

2. In the PowerShell terminal, run the following command to install Emacs using Chocolatey. choco install emacs -y

3. Run the following command to verify the Emacs version that you installed. emacs --version

You should see an output similar to the image below showing the Emacs version on your computer.

Editing and Saving a File

So you’ve installed Emacs. What next? Dive in and start editing a text file to see Emacs in action. Follow the steps below to edit and save a text file.

1. To open a file in Emacs, run the emacs command followed by the filename in PowerShell. The command below opens the file myPowerShellScript.ps1 for editing. The -nw switch tells emacs to open the editor within the current terminal window (PowerShell) and not in a separate GUI. emacs -nw myPowerShellScript.ps1

emacs -nw myPowerShellScript.ps1

Several dropdown menus will be available at the top of the editor. To view the Emacs help documentation, click the Help dropdown menu.

3. To exit the editor, press CTRL+X on your keyboard, followed by CTRL+C.

Searching and Replacing Text

Now that you know the basics of Emacs, how running a search and replace operation? Follow the steps below to do so.

1. Press CTRL+S and type in the text to search next to the I-search prompt to search for a text. The example below searches for the word Hello.

Conclusion

Throughout this tutorial, you have learned the basics of using three PowerShell text editors and the benefits of each. Next time you have to edit a file from the terminal, do not waste time setting up an external text editor. Simply open Nano, Vim, or Emacs and make your changes in a few keystrokes!

Which PowerShell text editor did you like best? Do you know of other text editors that weren’t in this tutorial?

I like using Visual Studio Code as my PowerShell script editor, but alternative editors exist. The built-in PowerShell ISE is usually there for you on Windows, but there’s a nice PowerShell module that you can use called PSEdit. In this blog post, I will show you how to use that as an alternative to VSCode.

  • What is PSEdit?
  • Installation
  • Using PSEdit
    • Opening files
    • Editing files
    • Running PowerShell code
  • Is it better than VSCode or ISE?

What is PSEdit?

It’s a PowerShell module that you can install to edit scripts in your PowerShell terminal with the following features:

  • IntelliSense
  • Syntax Highlighting
  • Format on Save
  • Script Execution
  • Error View
  • Syntax Error View

PSEdit is created and maintained by Ironman Software open-source projects. Visit them on their GitHub page here.

Installation

You can install the module by running the following:

Install-Module psedit

Opening files

After installing the module, you can use PSEdit to edit a file by running the following:

Show-PSEditor -Path .\file.path

Or you can start PSEdit by running Show-PSEditor and using File, Open to browse your script.

In the example below, I used PSEdit to edit my Export-Registry function:

As you can see, it has color coding and looks pretty nice 🙂

Editing files

When editing a file, PSEdit will use IntelliSense to autocomplete things, for example:

It will also highlight any incomplete parts or errors. In the example below, the bracket { is missing, and it highlights that in red:

It can also format your script if you have the PSScriptAnalyzer module installed (Install using Install-Module PSScriptAnalyzer followed by import-module PSScriptAnalyzer if not)

In the unformatted example below, for example:

PSEdit will change to this when using Edit, Format (CTRL-SHIFT-R):

It also has mouse support, which you can use to control the Menu. Right-Click will give you these options:

Running PowerShell code

You can execute the whole PowerShell script using Debug, Run (F5), or a selection (You can hold Shift and select multiple lines) by Debug, execution selection (F8). You can also run and exit PSEdit by using Debug, Exit and Run in Console (CTRL-SHIFT-F5)

Note: Write-Host output won’t show on the output screen. Write-Output does work

Any errors can be viewed by using View, Errors. Syntax errors can be displayed using View, Syntax Errors.

Is it better than VSCode or ISE?

It’s a lightweight alternative that is easy to use and doesn’t require any installation in Windows or MacOS other than installing the module itself. The benefit of PSEdit is that it can also run on Windows Server Core, in which you can’t use GUI apps, but you can also use it in a Linux shell if you have powershell installed on it (Which I do have installed on my Raspberry Pi 🙂 )

Problem Formulation

Given is a text file, say my_text_file.txt. How to modify its content in your Windows PowerShell working directory?

I’ll start with the most direct method to solve this problem in 90% of cases and give a pure PowerShell method afterward.

By the way, you can learn all about becoming a PowerShell developer in this blog post.

Method 1: Using Notepad

The easiest way to edit a text file in PowerShell on your Windows machine is to run the command notepad.exe my_text_file.txt, or simply notepad my_text_file.txt, in your PowerShell terminal to open the text file with the visual editor Notepad.

notepad.exe my_text_file.txt

You can also skip the .exe prefix in most cases:

notepad my_text_file.txt

Now, you may ask:

💡 Is Notepad preinstalled in any Windows installation? The answer is: yes! Notepad is a generic text editor to create, open, and read plaintext files and it’s included with all Windows versions.

Here’s how that looks on my Win 10 machine:

When I type in the command notepad.exe my_text_file.txt, PowerShell starts the Notepad visual editor in a new window.

I can then edit the file and hit CTRL + S to save the new contents.

But what if you cannot open a text editor—e.g. if you’re logged into a remote server via SSH?

Method 2: Pure PowerShell Approach

If you cannot open Notepad or other visual editors for some reason, a simple way to overwrite a text file with built-in PowerShell tools is the following:

  • Run the command echo 'your new content' > my_text_file.txt to print the new content using echo and pipe the output into the text file my_text_file.txt using >.
  • Check the new content using the command cat my_text_file.txt.
PS C:\Users\xcent\Test> echo 'hello universe!' > .\my_text_file.txt
PS C:\Users\xcent\Test> cat .\my_text_file.txt
hello universe!

Here’s what this looks like on my computer where I changed my_text_file.txt to contain the text 'hello universe!':

This is a simple and straightforward approach for small changes. However, if you have a large file and you just want to edit some minor details, this is not the best way.

Method 3: Install and Use Nano Text Editor

If you need a full-fledged solution to edit, potentially large, files in your Windows PowerShell, you need to do a quick installation.

I recommend the widely use Nano text editor for Windows machines. Here’s how it looks generally:

You can install the Nano text editor using the following approach outlined here.

First, install Chocolatey, a Windows package management solution, on your computer. This makes sure that you install trustworthy software packages from trustworthy sources. Download the latest version here.

Second, run the following choco install command in your PowerShell to install the nano editor:

choco install nano -y

Now, you can open and edit your file in your PowerShell using this command:

nano my_text_file.txt

Method 4: If you SSH’d to a Unix Machine

Of course, if you have logged in a Unix-based machine, you don’t need to install any editor because it comes with powerful integrated editors such as vim or emacs.

One of the following three commands should open your file in a terminal-based editing mode:

vim my_text_file.txt
vi my_text_file.txt
emacs my_text_file.txt

You can learn more about Vim here.

Method 5: New-Item and Add-Content CMDlets

To add a text file in PowerShell, you can use the New-Item cmdlet with the -ItemType parameter set to File.

Here are the steps:

  1. Open PowerShell by typing “powershell” in the search bar or press the Windows key + X and choose “Windows PowerShell” from the menu.
  2. Navigate to the directory where you want to create the file using the cd command. For example, if you want to create the file in the Documents folder, type cd Documents.
  3. Type the following command to create a new text file:
New-Item -ItemType File -Path "filename.txt"

Replace “filename” with the desired name of your text file.

  1. Press Enter to execute the command. This will create a new text file in the directory you navigated to.
  2. To add content to the text file, you can use the Add-Content cmdlet. For example, to add the text "Hello, World!" to the file, type the following command:
Add-Content -Path "filename.txt" -Value "Hello, World!"
  1. Press Enter to execute the command. This will add the text "Hello, World!" to the text file.

You can now view the text file by opening it in a text editor or by using the Get-Content cmdlet in PowerShell.

Summary

To edit a file.txt in PowerShell, use the command notepad file.txt to open a graphical editor on Windows.

If you need a simple file edit in your terminal without a graphical editor and without installation, you can use the command echo 'new content' > file.txt that overwrites the old content in file.txt with new content.

If you need a more advanced terminal-based editing approach, install the Nano text editor and run nano file.txt to open the file in editing mode.

If you’re SSH’d into a Unix machine, running the Vim console-based editor may be the best idea. Use vim file.txt or vi file.txt to open it.

Vim Windows Install Guide – How to Run the Vim Text Editor in PowerShell on your PC

Vim is a powerful code editor. So powerful that both Linux and Mac have it installed by default.

But if you are using Windows as your operating system, you will need to install Vim separately.

Fortunately, Microsoft makes it very easy to install Vim and get it running on your PC.

How to Download Vim

You can download the latest version of the Vim Text Editor straight from Vim themselves.

They have built a special self-executing installer that walks you through the process of installing Vim in the right location on your hard drive.

Note that for Windows you will technically download something called gVim, which is a version of Vim that includes a basic graphic user interface (GUI). You can install it by downloading this executable installer.

Image

A screenshot of what you’ll se when you attempt to open the file. Because this is an .exe file, Windows will ask your permission first.

Once you’ve downloaded the file, you just need to run it, and you’ll see a nice installation wizard that looks like this:

Image

A screenshot of the wizard you’ll see when you first run the Vim installer

They have a recommended «typical» installation. but if you have a reasonably large hard drive, there’s no harm in going ahead with installing everything by choosing the «full» option:

Image

A screenshot of the Vim installer where you can choose what parts of Vim you want to install.

How to Run Vim in PowerShell

Then, once you’ve installed Vim, you should be able to launch it from your Windows command prompt.

Note that as of 2020, PowerShell has all of the same functionality as CMD, plus a whole lot more. I recommend using PowerShell for everything.

You can open PowerShell from the Windows menu bar by typing «powershell» in the search field on the start bar.

Windows will open PowerShell, and you’ll get a command prompt that looks something like this:

Image

A screenshot of the Windows PowerShell prompt.

Once you’re in PowerShell, here’s how to run Vim itself. All you have to do is type «vim» and press enter. This will open up Vim. Once Vim is open, this is what you should see:

Image

A screenshot of Vim when you open it for the first time.

Congratulations – you now have Vim installed.

How to run Vim inside VS Code

If you are already using VS Code, and want a lot of the speed of Vim without losing the functionality of VS Code, I have good news. It is possible to run a Vim-like experience right within VS Code.

Here is a Vim plugin for VS Code that will help you do this. At the time of me writing this, this plugin has been installed nearly 2 million times.

How to Learn How to Use Vim Properly

Vim is a powerful code editor, and it will take you a lot of practice to get comfortable with it.

Here are a few Vim tutorials that will really help you quickly grasp the basics and get your fingers flying in no time.

For starters, one way Vim is different from other code editors is that Vim has «modes». Here are all of Vim’s modes explained, with examples.

Vim can be intimidating. There is so much to learn. But this guide will show you how not to be afraid of Vim anymore.

If you’re already using VS Code and want to switch completely to Vim, this article will explain how you can do so.

And here are 7 Vim Tips That Changed #100DaysOfCode founder Alex Kallaway’s life. In this article, he not only explain these, but shows demos of these tips in action.

Vim: Learn it, live it, love it.

In the 30 years since Bram Moolenaar first created Vim, its influence has spread far and wide. And even today, the Vim project is actively maintained and constantly improving.

I’ve met so many developers over the years who swear by Vim.

I hope this guide has helped you get running Vim on your Windows PC. And I hope these other tutorials I’ve shared with you here will help you go from zero-to-sixty within the coming months.

The key is to keep practicing and not get discouraged by how many Vim shortcuts there are to remember. Eventually, all of these will become muscle memory, and you’ll be flying from one file to another, banging out code like a terminator.

There is no feeling quite as cool as being able to drop into a codebase and immediately start making changes without ever even reaching for a mouse or trackpad. That is the power that Vim promises, and delivers in spades.

To edit a file in PowerShell, you can use the `Set-Content` cmdlet to overwrite the file’s contents or the `Add-Content` cmdlet to append data to it.

Here’s an example of using `Set-Content`:

Set-Content -Path 'C:\path\to\your\file.txt' -Value 'This is the new content of the file.'

Understanding PowerShell and File Editing

What is PowerShell?

PowerShell is a powerful command-line interface and scripting language designed for system administration and automation. Unlike traditional command-line interfaces, PowerShell integrates with .NET, allowing it to interact seamlessly with system objects, making it a versatile tool for managing files and configurations.

Key Concepts in File Editing

When dealing with file editing in PowerShell, it’s essential to understand what types of files you might typically encounter. Common file types include:

  • Text files (.txt): Simple files containing plain text.
  • Comma-Separated Values (.csv): Often used for data import/export.
  • JSON (.json): Commonly used for configuration files in modern applications.

Understanding file encoding is also crucial. Different types of files may use different encoding formats, such as UTF-8 or ASCII. This can influence how data is read from or written to files.

How to Paste in PowerShell: A Quick Guide

Opening a File for Editing in PowerShell

Using `Get-Content` to View File Content

Before making any edits, you often need to view the file’s current state. The `Get-Content` cmdlet allows you to accomplish this easily. For example:

Get-Content -Path "C:\example\file.txt"

This command will display the contents of `file.txt` in the console. You can specify the full path where the file is located, and PowerShell will read the information line by line.

Editing Files with Out-File

Once you know the content, you might want to overwrite it. The `Out-File` cmdlet allows you to create a new file or replace an existing one with the new data. Here’s how you can use it:

"New content" | Out-File -FilePath "C:\example\file.txt" -Encoding UTF8

In this example, `Out-File` writes the string «New content» to `file.txt`. By using the `-Encoding` parameter, you can specify the encoding format, such as UTF8, ensuring that special characters are handled correctly.

Explanation of Overwriting vs. Appending

Using `Out-File` by default will overwrite any existing content in the file. If you want to add additional information instead of replacing it, consider using the `-Append` flag:

"Additional content" | Out-File -FilePath "C:\example\file.txt" -Append

This will append «Additional content» to whatever is already in `file.txt`.

Editing Files In-Place

Using `Set-Content` to Modify File Content

To change existing content directly in a file, use the `Set-Content` cmdlet. For example:

Set-Content -Path "C:\example\file.txt" -Value "Updated content"

With this command, the entire content of `file.txt` will be replaced with «Updated content». It’s handy for quickly changing text.

Using `Add-Content` to Append Data

If your goal is to add rather than replace, the `Add-Content` cmdlet is perfect. It allows you to insert new lines or text seamlessly. For instance:

Add-Content -Path "C:\example\file.txt" -Value "This line is appended."

This command will add «This line is appended.» to the end of `file.txt`, preserving all previous information.

More Advanced Editing Techniques

Regular Expressions for Complex Replacements

When you need to perform more complex text manipulations, Regular Expressions (Regex) come into play. Here’s a brief example of how to replace occurrences of a string within a file:

(Get-Content -Path "C:\example\file.txt") -replace 'old', 'new' | Set-Content -Path "C:\example\file.txt"

In this scenario, `Get-Content` retrieves the file’s contents, the `-replace` operator modifies it by substituting «old» with «new,» and finally, `Set-Content` writes the changes back to the file. This method allows you to replace multiple occurrences easily.

Using Built-in PowerShell Cmdlets for File Editing

PowerShell provides a range of cmdlets that enhance your file editing capabilities. For example, the `Select-String` cmdlet helps you search for specific patterns within text files. Here’s how to use it:

Select-String -Path "C:\example\file.txt" -Pattern "search term"

This command searches for «search term» in `file.txt` and returns the line(s) containing it. This is invaluable when you are dealing with large files.

Practical Scenarios for File Editing

Editing Configuration Files

A common scenario involves editing configuration files essential for applications. For instance, if you need to change a setting in a JSON file, you might do something like this:

(Get-Content -Path "C:\example\config.json") -replace '"oldSetting": true', '"oldSetting": false' | Set-Content -Path "C:\example\config.json"

This command would change a setting in `config.json` from `true` to `false`, which can be crucial for performance tuning or feature enabling.

Batch Editing Multiple Files

PowerShell shines when it comes to bulk operations. If you need to update multiple files in a directory, you can employ a loop:

Get-ChildItem -Path "C:\example\*.txt" | ForEach-Object {

Best Practices for Editing Files in PowerShell

When editing files in PowerShell, it’s essential to follow a few best practices for a smooth experience:

  • Always Backup Files Before Editing: Before making changes, ensure you have a copy of the original file. This provides a safety net in case things go wrong.

  • Use Version Control Systems: For larger projects, using tools like Git for version tracking can save time and help manage revisions effectively.

  • Test Changes in a Controlled Environment: If possible, test scripts on non-critical systems before deploying to live environments. This minimizes the risk of unintended consequences.
