Let's say I had a text file with the following nine lines:
foo
bar
baz
qux
quux
How can I use Sublime Text 2 to remove all four of the blank/empty lines, leaving only five lines?
Select the text
Press:
Make sure you have selected 'regular expression' by pressing:
Find what: ^\n
or ^(\r|\n\r?)
Replace With: (nothing, leave in blank).
