$string = "This is a string with`r`nnewlines."
$cleanString = $string -replace "`r`n", ""

How to remove all crlf from a text file using PowerShell?

You can remove all CRLF (Carriage return Line feed) characters from a text file using PowerShell by following these steps:

  1. Open PowerShell by searching for it in the start menu or by pressing Win + X and selecting "Windows PowerShell" or "Windows PowerShell (Admin)".
  2. Use the following PowerShell command to remove all CRLF characters from a text file: 
1

(Get-Content -Path "Path\to\your\file.txt" -Raw) -replace "\r\n", "" | Set-Content -Path "Path\to\your\output\file.txt"


Replace "Path\to\your\file.txt" with the path to your input text file and "Path\to\your\output\file.txt" with the path to your output text file.


This command reads the content of the input file, removes all occurrences of CRLF characters, and then saves the modified content to the output file.

  1. Run the command in PowerShell, and it will remove all CRLF characters from the text file specified.


After running this command, the output file will contain the same content as the input file, but with all CRLF characters removed.

How do I replace crlf with space in PowerShell?

You can use the -replace operator in PowerShell to replace the newline characters (CRLF) with a space. Here is an example:

1
2
3

$text = "This is a sample text`r`nwith newline characters`r`nthat I want to replace."
$newText = $text -replace "`r`n", " "
$newText


In this example, we are replacing the carriage return (r) and line feed (n) characters (CRLF) with a space in the $text variable. The resulting text will be stored in the $newText variable.


What is the difference between cr and lf in PowerShell?

In PowerShell, both "CR" (Carriage Return) and "LF" (Line Feed) are control characters used to signify the end of a line in a text file.


The main difference between CR and LF is that CR moves the cursor to the beginning of the current line, while LF moves the cursor to the next line.


In PowerShell, the `n character represents a new line, which is equivalent to using a combination of both CR and LF.


For example, when working with text files in PowerShell, you may need to use r (Carriage Return) or n (Line Feed) characters to control the layout and structure of the text.
