Powershell script problem (Get-content vs assigning to variable)

Question

Hello everyone,

I'm attempting to write a Twitter Powershell script that will use community created interfaces PoshTwitter with the Twitter API to attempt and find a list of followers who are potential spammers.

I have a feeling that my problem lies not with the particular cmdlet I'm calling (Get-TwitterFollowers), but rather with the difference between assigning a variable:

If I try this:

$rawFol = get-twitterfollowers -page $page -raw 1

$rawFol is different than if I do this:

get-twitterfollowers -page $page -raw 1 > .\page$page.txt
$rawFol = gc .\page$page.txt

The Get-TwitterFollowers cmdlet returns an XML file converted to string.

What things can I try to determine the differences between these two assignments? They look like they'd result with same content.

The difference you're seeing is how powershell handles new lines in strings. When calling the get-twitterfollowers CmdLet, it is either returning a single string or an array of strings. My guess by your description is that it returns a string. So the $rawFol variable will have a single string value. Any new lines are simply embedded into the string value.

The second command you write the return to a file. Now all of the newlines in the string are represented as lines in the file. Later when you call gc on that file, each line will be returned as a separate string. So the $rawFol variable will now have an array of strings.
