    I use Meld. It’s easy for compare files/folder

    I’m trying to walk away from a 2010 macbook. I’ve replaced all functionality except for filemerging. The last reason I have to book my mac is I’m the diff /merge utility in the free program TextWrangler (now BBedit) being irreplaceable.

    Do any of these or any program offer both line level and word level merging in a graphic environment? With BBedit, I can walk through a work and use content from either input file without much need to re-key any of it, I’m just selecting a or b, either at the line level, or word level. I’ve not been able to find anything in Linux that does this, line level only.

    Hey Aaron, thanks for the article. Do you have any benchmark comparing the software? I am asking because I use Meld and making a diff of a 100Mb SQL file just take forever, a little better if I turn off the syntax coloring but still take forever…

    Got any advice for comparing large files?

    Thanks in advance

    Ughh… sorry but “Intuitive GUI” does not describe Kdiff3. I mean, Kdiff3 is probably the best merge-tool available for any version control environment and I do use it roughly weekly. However, after using it for 10 years, I still find its GUI barely usable. I would describe it as best tool for file merging despite horrific GUI.

    Thanks for this write-up on the diff tools. The best I’ve ever read with the most tools!

    I use the Intellij Community Edition (Open Source). It can even be run as stand-alone diff tool. It is available for all platforms. I use it equally on Debian GNU/Linux and Windows.
