Removing blank lines?

How to eliminiate the blank lines from log file?
Can it be done through regular expressions /^$/

Thanks,

There is a way I often see used but it doesn't work if some of the
"empty lines" happen to have whitespace:

PS > gc Test.txt | select-string .

Here is a way that does seem to work:

PS > gc Test.txt | ? { $_ -notmatch "^$|^\s+$" }
One The next line is blank
Two Next, a line that has three spaces and three tabs
3 987 654
,%~` !@$!@#$
Five And this is the end.
PS > gc Test.txt

I think that the regex could be simplified to '^\s*$'.
