Removing empty lines in Notepad

Question

How can I replace empty lines in Notepad    I tried a find and replace with the empty lines in the find  and nothing in the replace  but it did not work  it probably needs regex

You need something like a regular expression.

You have to be in Extended mode

If you want all the lines to end up on a single line use \r\n. If you want to simply remove empty lines, use \n\r as @Link originally suggested.

Replace either expression with nothing.

This obviously does not work if the blank lines contain tabs or blanks  Many web pages  e g  http   www guardian co uk   contain these white lines  as a result of a faulty HTML editor   Remove white space using regular expression as follows      change pattern    t       into nothing    where   t   matches either tab or space      matches one or more occurrences  and     marks the end of line   Then use notepad   textFX to remove single or extra empty lines  Be sure that these blank lines are not significant in the given context
