Remove blank lines

¿How can i remove blank lines between all lines in a long text file?

Example

WrongFile.txt :
Line 1

Line 2

Line 3

CorrectFile.txt :
Line 1
Line 2
Line 3

Thanks in advance

grep -v '^$' file_name > file_name.$$

mv file_name.$$ file_name

Hope this helps,
Jingi

sed '/^$/d' wrongfile > correctfile

in case the "empty" lines might contain blank characters:

grep -v '^[<spc><tab>]*$' Yourfile > correctfile

or (this one's for RishiPahuja):

sed '/^[<spc><tab>]*$/d' Yourfile > correctfile

(replace "<spc>" and "<tab>" with space and tab characters)
