To read powershell stdout, you can use the Out-Host cmdlet to display output directly in the console window. Alternatively, you can use the Out-String cmdlet to convert the output to a string object that can be stored in a variable and manipulated further. You can also redirect the stdout to a file using the > operator or by using the Start-Process cmdlet with the -RedirectStandardOutput parameter. Additionally, you can use the Get-Content cmdlet to read the contents of a file that contains the stdout output.

How to stop PowerShell stdout from automatically scrolling?
To stop PowerShell stdout from automatically scrolling, you can use the more command at the end of your PowerShell commands.
For example, if you have a command that outputs a lot of information and you want to stop the automatic scrolling, you can add | more at the end of the command like this:
1
|
Get-Process | more
|
This will display the output of the command one page at a time, and you can press spacebar to scroll through the output manually.
Alternatively, you can also use the -NoMore parameter with the Out-Host cmdlet like this:
1
|
Get-Process | Out-Host -NoMore
|
This will prevent automatic scrolling of the output and you can manually scroll through the information using the scrollbar.
You can also adjust the buffer size in PowerShell to prevent automatic scrolling by going to the settings and increasing the buffer size.
These are some ways you can stop PowerShell stdout from automatically scrolling.
How to highlight specific text in PowerShell stdout?
One way to highlight specific text in PowerShell stdout is to use color codes. You can make use of the Write-Host cmdlet to display text in different colors. Here's an example that highlights the text 'specific text' in yellow:
1 2 3 |
Write-Host "This is a sample text with specific text highlighted" -NoNewline Write-Host "specific text" -ForegroundColor Yellow -NoNewline Write-Host " additional text" |
In this example, the -NoNewline parameter is used to ensure that the text is displayed on the same line. The text 'specific text' is displayed in yellow using the -ForegroundColor parameter.
You can customize the color and appearance of the text by using different color codes and options available in the Write-Host cmdlet.
How to filter PowerShell stdout output?
To filter PowerShell stdout output, you can use the | (pipe) operator to send the output to the Select-String cmdlet, which allows you to filter the output using a regular expression.
For example, if you want to filter the output to only show lines that contain the word "error", you can use the following command:
1
|
<command that produces output> | Select-String "error"
|
You can also use other cmdlets like Where-Object to filter the output based on certain conditions. For example, to filter output where the line length is greater than 80 characters, you can use the following command:
1
|
<command that produces output> | Where-Object { $_.Length -gt 80 }
|
You can also combine multiple filters together to further refine the output as needed.
