Also from notepad years ago. How in atom to delete all lines not containing a specified string? Thanks
I also need to delete all blank lines.
With this package ? https://atom.io/packages/delete-whitelines
Thanks for replying. I tried that earier it and it doesn’t work for me - some popup window is displayed. I dug on my old Windows laptop, downloaded Notepad++ and got what I needed.
