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

Answer 1

^\s*$

If you've got perl-compatible regex.

Answer 2

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

^[ \t]*$

Answer 3

According to this blog post on wordpress.com, it's

^[[:space:]]*$

Answer 4

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]*
