Thank you both for your input.
I find it very confusing that this doesn't work :
PS C:\Users\Xavier\Desktop> $somevar = "power`nshell`nrocks"
PS C:\Users\Xavier\Desktop> select-string -inputobject $somevar -pattern
"power`nshell" -quiet
True
PS C:\Users\Xavier\Desktop> set-content test.txt $somevar
PS C:\Users\Xavier\Desktop> get-content test.txt
power
shell
rocks
PS C:\Users\Xavier\Desktop> get-content test.txt | select-string "power"
-quiet
True
PS C:\Users\Xavier\Desktop> get-content test.txt | select-string
"power\nshell" -quiet
PS C:\Users\Xavier\Desktop> get-content test.txt | select-string
"power`nshell" -quiet
PS C:\Users\Xavier\Desktop>
So the pattern matches the variable content, but not the file content.
From what I understand, this is because the first variable is a string, and
the second is an array.
Keith's solution will work in that case :
PS C:\Users\Xavier\Desktop> $lines = get-content test.txt
PS C:\Users\Xavier\Desktop> $text = [string]::Join("`n", $lines)
PS C:\Users\Xavier\Desktop> select-string -inputobject $text -pattern
"power`nshell" -quiet
True
Thanks a lot,
Xavier
