xxdiff is a graphical file and directories comparison and merge tool. It can be used for viewing the differences between two or three files, or two directories, and can be used to produce a merged version. The texts of the two or three files are presented side by side with their differences highlighted with colors for easy identification.
The paths supplied on the command line identify the files to be compared. The paths may be one of three things: a regular file, a directory or a '-', in which case the input for that path will be read from standard input. If the paths are all directories, a directory diff will be performed. If at least one path is a file or a '-', a file diff will be performed. If there are directory names along with file names, the basename of the file name will be appended to the directory names to find the other files to compare with. If there are multiple file names specified and some directories names as well, xxdiff bails out, since it doesn't know which basename to use for the missing one.
Please consult xxdiff --help for more documentation.
