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.
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 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. The most popular ways to display changes are either side-by-side, or a consolidating view that highlights data inserts, and ...
Main concerns for data differencing are usability and space efficiency (patch size).. If one simply wishes to reconstruct the target given the source and patch, one may simply include the entire target in the patch and "apply" the patch by discarding the source and outputting the target that has been included in the patch; similarly, if the source and target have the same size one may create a ...
Git does periodic repacking automatically, but manual repacking is also possible with the git gc command. [46] For data integrity, both the packfile and its index have an SHA-1 checksum [47] inside, and the file name of the packfile also contains an SHA-1 checksum. To check the integrity of a repository, run the git fsck command. [48] [49]
Manual merging is also required when automatic merging runs into a change conflict; for instance, very few automatic merge tools can merge two changes to the same line of code (say, one that changes a function name, and another that adds a comment). In these cases, revision control systems resort to the user to specify the intended merge result.
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. This ...
