In the new version(5.7) of NotePad++, the convert to UNIX format function is missing in its usual menu link which is

Encoding --> Convert to UNIX

For those doing shell scripting and related things, this is very important. The convertion of CRLF to LF is a pain and NotePad++ is a saviour(ok, other text editors can do that, too). So fret not, fretful folks, they just moved. It is now in the menu link below.

Edit --> EOL Conversion --> UNIX (or Windows or MAC)

Here's the screenshots in case it isn't clear yet.

As to why it was moved there is beyond me in terms of usability. But it's a free software so we can just sigh. Here's the source of information http://sourceforge.net/projects/notepad-plus/forums/forum/331754/topic/3495842
