Regex for white space and then line end

Question

I am struggling to find this - I need to strip all empty lines which might have white space before them

The alternative is messing about in Excel - I am using TextPad

Why?? Trim and then filter will do this quite easily - The suggestion below dont work in TextPad.... — Jack Kada, Feb 15 '10 at 12:17

In Textpad: First find blank line: F5, then ^\s*$

Next mark 'em: in the find dialog, click the "Mark All" button. You see right-carets next to each blank line.

Then delete 'em: Select Edit->Delete ->Bookmarked Lines

After years of using Textpad never knew this existed ... was exactly what I was looking for. – KornMuffin Oct 13 '15 at 19:10

A simple reg ex for any empty line which may contain white space is:

^[ \t]*$

Since you want to remove the line, this will not do:

^\s*$

You need to remove the line break after the empty line:

^\s*$[\n\r]*
