In computing, the utility diff is a data comparison tool that computes and displays the differences between the contents of files. Unlike edit distance notions used for other purposes, diff is line-oriented rather than character-oriented, but it is like Levenshtein distance in that it tries to determine the smallest set of deletions and insertions to create one file from the other.
The optimal way to display the results of a file comparison depends on many factors, including the type of source data. The fixed lines of programming code provide a clear unit of comparison. This does not work with documents, where adding a single word may cause the following lines to wrap differently, but still not change the content.
Unstructured merge operates on raw text, typically using lines of text as atomic units. This is what Unix tools (diff/patch) and CVS tools (SVN, Git) use. This is limited [opinion], as a line of text does not represent the structure of source code.
The weave-diff can compare paragraphs word-for-word if moved, but not if split. A diff shows differences per line, so it synchronizes between revisions by matching the newlines and unchanged lines. Some editors find that having additional line breaks to break up the text improves the diff function.
To obtain a copy of the URL for the diff, right-click on its (prev) button and select "Copy link location", "copy shortcut", or however your browser expresses it. The URL of the diff you want is now in your clipboard. Alternatively, you can click (prev) and, when you are viewing the new page, copy its URL from the address bar.
The computer tool patch is a Unix program that updates text files according to instructions contained in a separate file, called a patch file.The patch file (also called a patch for short) is a text file that consists of a list of differences and is produced by running the related diff program with the original and updated file as arguments.
The primary distinction between comm and diff is that comm discards information about the order of the lines prior to sorting. A minor difference between comm and diff is that comm will not try to indicate that a line has "changed" between the two files; lines are either shown in the "from file #1", "from file #2", or "in both" columns.
