Writing new lines to a text file in PowerShell

Writing new lines to a text file in PowerShell

In PowerShell, you can use the Out-File cmdlet to write data to a text file, including new lines. Here's how you can do it:

# Define the file path $filePath = "output.txt" # Write data to the file "Line 1" | Out-File -FilePath $filePath -Encoding utf8 "Line 2" | Out-File -FilePath $filePath -Encoding utf8 -Append "Line 3" | Out-File -FilePath $filePath -Encoding utf8 -Append # Output a message Write-Host "Data has been written to $filePath"

Explanation:

  • We define the file path where we want to save the text file.
  • We use the Out-File cmdlet to write each line of data to the file. The -Append parameter is used to append data to the file without overwriting existing content.
  • We specify the -Encoding utf8 parameter to ensure that the file is saved using UTF-8 encoding.
  • Finally, we output a message indicating that the data has been written to the file.

You can run this PowerShell script in a PowerShell environment to create a text file named "output.txt" with the specified data. Adjust the file path and the data as needed.
