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.
git add [file], which adds a file to git's working directory (files about to be committed). git commit -m [commit message], which commits the files from the current working directory (so they are now part of the repository's history). A .gitignore file may be created in a Git repository as a plain text file.
File comparison is an important, and integral process of file synchronization and backup. In backup methodologies, the issue of data corruption is important. Rarely is there a warning before corruption occurs, this can make recovery difficult or impossible. Often, the problem is only apparent the next time someone tries to open a file.
For instance, if patch A adds line "X" after line 7 of file F and patch B adds line "Y" after line 310 of file F, B has to be rewritten if it is rebased on A: the line must be added on line 311 of file F, because the line added in A offsets the line numbers by one.
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 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.
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.
