The text file
Line1:abcd
Line2:cdef

Line4:casdj

First of all, this isn't relevant to DPM so would have been more appropriate being posted in

That said, doing what you're after is fairly straight forward, though the exact method depends on what you're trying to achieve.
If you want to update the existing file c:\input.txt so that same file ends up with the spaces removed, then use :
(Get-Content C:\input.txt) |
Foreach-Object {$_ -replace " ",""} |
Set-Content C:\input.txt
Alternatively, if you're trying to load those values into a variable ($foo) but with the spaces removed then you can use :
$foo = (Get-Content C:\input.txt) |
Foreach-Object {$_ -replace " ",""}
