I know this is a noob question, but how can I diff 2 tabs or files, and only select the differences?
IE: I have 2 files with a list computer names, I want to find only the systems missing from 1 file and select the missing systems so that I can put them into a new file.
If I understand correctly what you are asking, you probably want to use the external option by linking easydiff to a 3rd party merge tool. The internal diff functionality is great for quickly seeing the difference. But for merging, I use EasyDiff's external option and merge in an actual merge utility.
If you want to merge inside Sublime, then take a look at Sublimerge http://www.sublimerge.com/
. I, personally, have a hard time paying for a merge tool that only works with Sublime, which is why I use EasyDiff connected to a good external merge tool when I actually need to merge.
