You can use    r  n  also for the new line in powershell  I have used this in servicenow tool   In my case   r n  s not working so i tried    r  n  as     this symbol work as escape character in powershell

If you want to remove all new line characters and replace them with some character  say comma  then you can use the following   Get-Content test txt  -join  quot   quot   This works because Get-Content returns array of lines  You can see it as tokenize function available in many languages

In my understanding  Get-Content eliminates ALL newlines carriage returns when it rolls your text file through the pipeline  To do multiline regexes  you have to re-combine your string array into one giant string  I do something like    text    string   Join   n    Get-Content test txt    regex   Replace  text   t n    ting na     Singleline     Clarification  small files only folks  Please don t try this on your 40 nbsp GB log file

A CRLF is two characters  of course  the CR and the LF  However   n consists of both  For example   PS C   gt   x    Hello  gt  gt  World   PS C   gt   x Hello World PS C   gt   x contains   n   True PS C   gt   x contains   r   False PS C   gt   x replace  o nW   o There nThe W   Hello There The World PS C   gt    I think you re running into problems with the  r  I was able to remove the  r from your example  use only  n  and it worked  Of course  I don t know exactly how you generated the original string so I don t know what s in there
