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'
This question is related to
powershell
line-breaks
I think I found it. All you have to do is type in "`n" (WITH THE QUOTATION MARKS!)
Thanks!
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.
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 ` -p 5672:5672 ` -p 15672:15672 ` --restart=always ` --hostname rabbitmq-master ` -v c:\docker\rabbitmq\data:/var/lib/rabbitmq ` rabbitmq:latest
Just in case someone else comes across this, to clarify the answer `n is grave accent n, not single tick n
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.....
}
