How to break lines in PowerShell?
PowershellLine BreaksPowershell Problem Overview
I am [completely new to PowerShell and] concatenating a string in a loop, if a special condition occurs I should insert a line break...how can I do this?
Basically looking for the equivalent of \n.
$str = ""
foreach($line in $file){
if($line -Match $review){ #Special condition
$str += ANSWER #looking for ANSWER
}
#code.....
}
So far I have tried
"\n" '\n' "\N" '\N' "\r" '\r' "\R" '\R' '`n' '`r' '-n' '-r'
Powershell Solutions
Solution 1 - Powershell
Try "`n" with double quotes. (not single quotes '`n' )
For a complete list of escaping characters see:
Help about_Escape_character
The code should be
$str += "`n"
Solution 2 - Powershell
I think I found it. All you have to do is type in "`n" (WITH THE QUOTATION MARKS!)
Thanks!
Solution 3 - Powershell
If you are using just code like this below, you must put just a grave accent at the end of line `.
docker run -d --name rabbitmq docker run -d --name rabbitmq -p 5672:5672
-p 15672:15672 --restart=always
--hostname rabbitmq-master -v c:\docker\rabbitmq\data:/var/lib/rabbitmq
rabbitmq:latest
-p 15672:15672 docker run -d --name rabbitmq docker run -d --name rabbitmq -p 5672:5672
-p 15672:15672 --restart=always
--hostname rabbitmq-master -v c:\docker\rabbitmq\data:/var/lib/rabbitmq
rabbitmq:latest
-p 15672:15672 --restart=always
--hostname rabbitmq-master -v c:\docker\rabbitmq\data:/var/lib/rabbitmq
rabbitmq:latest
--hostname rabbitmq-master docker run -d --name rabbitmq docker run -d --name rabbitmq -p 5672:5672
-p 15672:15672 --restart=always
--hostname rabbitmq-master -v c:\docker\rabbitmq\data:/var/lib/rabbitmq
rabbitmq:latest
-p 15672:15672 docker run -d --name rabbitmq docker run -d --name rabbitmq -p 5672:5672
-p 15672:15672 --restart=always
--hostname rabbitmq-master -v c:\docker\rabbitmq\data:/var/lib/rabbitmq
rabbitmq:latest
-p 15672:15672 --restart=always

Solution 4 - Powershell
Just in case someone else comes across this, to clarify the answer `n is grave accent n, not single tick n
Solution 5 - Powershell
You can also just use:
Write-Host "";
Or, to put it in terms of your specific question:
$str = ""
foreach($line in $file){
if($line -Match $review){ #Special condition
$str += Write-Host ""
$str += ANSWER #looking for ANSWER
}
#code.....
}
Solution 6 - Powershell
If escaping doesn't work, you can try this:
$str += $("" | Out-String)
It just adds nothing, but as an Out-String, which creates a new line.
