How to Capture Openssh Output on Powershell?

To capture the output of an OpenSSH command in PowerShell, you can use the standard output redirection operator ">" to redirect the output to a file.

For example, if you want to capture the output of an "ssh" command to a file called "output.txt", you can use the following syntax:

ssh user@hostname command > output.txt

This will run the command on the remote server using SSH and capture the output to the specified file "output.txt".

You can also capture the output as a string variable in PowerShell by assigning the output to a variable, like this:

$output = ssh user@hostname command

This will store the output of the SSH command in the variable $output, which you can then use in your PowerShell script.

How to store openssh output in a variable in powershell?

You can store the output of an OpenSSH command in a variable in PowerShell using the Invoke-Expression cmdlet. Here's an example of how you can do this:

1

$output = Invoke-Expression "ssh user@hostname 'ls -l'"

In this example, the ssh user@hostname 'ls -l' command is executed using the Invoke-Expression cmdlet and the output is stored in the $output variable. You can then access and manipulate the output stored in the variable as needed in your PowerShell script.

What is the best way to capture openssh output on powershell?

To capture OpenSSH output in PowerShell, you can use the Start-Process cmdlet with the redirect standard output and error stream to capture the output in a variable. Here is an example:

1
2
3
4
5
6
7
8
9

$output = Start-Process -FilePath ssh -ArgumentList "user@hostname" -NoNewWindow -PassThru -Wait -RedirectStandardOutput output.txt -RedirectStandardError errors.txt

# Read the output
$outputText = Get-Content output.txt
$errorsText = Get-Content errors.txt

# Print the output
Write-Output $outputText
Write-Output $errorsText

In this example, the Start-Process cmdlet is used to run the ssh command to connect to a remote host. The output and error streams are redirected to separate text files, which can then be read and printed in PowerShell.

Alternatively, you can pipe the output of the ssh command to a variable directly using the $output = $(ssh user@hostname) syntax. This will capture the output of the command directly in the variable without the need to redirect to a file.

Choose the method that best suits your needs depending on whether you want to capture the output in a file or in a variable.

How to append openssh output to an existing file in powershell?

To append the output of OpenSSH to an existing file in PowerShell, you can use the following command:

1

ssh user@host command | Out-File -Append -FilePath "path\to\existing\file.txt"

Replace user@host with the username and hostname of the SSH server you are connecting to, command with the command you want to run on the SSH server, and "path\to\existing\file.txt" with the path to the existing file you want to append the output to.

This command will run the specified command on the SSH server and append the output to the existing file in the specified path.

How to format openssh output in powershell?

To format the output of OpenSSH in PowerShell, you can use the "Format-Table" cmdlet to display the output in a tabular format. Here's an example of how to do this:

1. After running the OpenSSH command in PowerShell, pipe the output to the "Format-Table" cmdlet. For example:

1

ssh user@hostname | Format-Table

1. You can also specify which properties of the output you want to display in the table by using the "-Property" parameter. For example, to display only the "Name" and "Size" properties of the output, you can use the following command:

1

ssh user@hostname | Format-Table -Property Name, Size

1. You can also format the table with specific column widths and alignments. For example, to set the column width for the "Name" column to 20 characters and align the "Size" column to the right, you can use the following command:

1

ssh user@hostname | Format-Table -Property Name, Size -AutoSize -Property @{Label="Name"; Expression={$_.Name}; Width=20}, @{Label="Size"; Expression={$_.Size}; Alignment="Right"}

By using the "Format-Table" cmdlet with these options, you can easily format the output of OpenSSH commands in PowerShell to display the information in a more readable and organized way.
