How to verify that the files are copied without problems?Ĭhecksums are better long term. I can highly recommend BeyondCompare from. Ediff also works with remote and compressed files, automatically ftp'ing them over and uncompressing them.Best tools to show the difference in files between two cloned drives? Ediff is using the same algorithm as patch to determine which files need to be patched.)Įdiff is aware of version control, which lets you compare files with their older versions. All other patches are treated as 1-file patches. Since Ediff lets you copy differences between variants, you can, in effect, apply patches selectively (i.e., you can copy a difference region from file.orig to file, thereby undoing any particular patch that you don't like).Įdiff even understands multi-file patches and can apply them interactively! (Ediff can recognize multi-file patches only if they are in the context format or GNU unified format. You can even apply a patch right out of a mail buffer, i.e., patches received by mail don't even have to be saved. In addition, Ediff can apply a patch to a file and then let you step through both files, the patched and the original one, simultaneously, difference-by-difference.
Furthermore, Ediff is equipped with directory-level capabilities that allow the user to conveniently launch browsing or merging sessions on groups of files in two (or three) different directories. Merging with an ancestor file is also supported. You can also copy difference regions from one buffer to another (and recover old differences if you change your mind).Īnother powerful feature is the ability to merge a pair of files into a third buffer. The files being compared, file-A, file-B, and file-C (if applicable) are shown in separate windows (side by side, one above the another, or in separate frames), and the differences are highlighted as you step through them. Ediff is a comprehensive visual interface to Unix diff and patch utilities.Įdiff provides a convenient way for simultaneous browsing through the differences between a pair (or a triple) of files or buffers (which are called ‘variants’ for our purposes).
