Remove empty lines in a txt file
I know the only solution : techmechanics

But I would like a free desktop option. Better is portable.

I use Notepad ++, click menu Edit, select Line Operations, then select:

• Remove Empty Lines, or
• Remove Empty Lines (Containing blank characters)

Also you can use Notepad2 (portable version is available, ):

• Select the text
• Press Alt+R (or via menu Edit|Block|Remove Blank Lines)

You may want to try Dolphin Text Editor Menu.
It runs in the tray, triggered via hotkey.

I'll second that.  Very convenient.

My Clipboard Help and Spell program will happily take the text selected in any program and do manipulations including removing blank lines, and then paste it back (replacing the original text), and let you set up a hotkey to do this.

Use sed?

I have notepad++
Running to do

Download this:
http://gnuwin32.sourceforge.net/packages/sed.htm

Put it in somewhere in your %PATH%, unless the installer does it for you (haven't tested).

Then do this:

Code

sed -i '/^$/d' filewithblanklines.txt

With a little registry magic, you can even add it as a context menu item.  Look here:

My registry knowledge is a bit rusty, or else I'd tell you exactly how with a .reg file so it only opens up when you right-click TXT files.
Any takers?

Remove empty lines in a txt file

See file content:

Code: (generic)

C:\>TYPE input.txt

Filter for lines not (/V) being empty (^$):

Code: (generic)

C:\>TYPE input.txt | findstr /V "^$"

(piping (|) the output of type to the input of findstr)
(for empty lines possible containing whitespace use: "^\s*$")



Filter and write to new file:

Code: (generic)

C:\>TYPE input.txt | findstr /V "^$" > output.txt
