imediff2 - An interactive fullscreen 2-way merge tool

Merge two (slightly different) files interactively with a user friendly fullscreen interface in text mode.

imediff2 shows the differences of given two files (in color if the terminal supports them), lets you scroll the file and toggle changes between old and new version one by one. If the 'unresolved' mode is enabled, you can optionally save both versions.

Empty lines are shown in reverse so you see that you can select them. If a line is missing completely from one file, imediff2 displays it as a reversed '?'. While it seems to take one line in the editing phase, it is naturally not saved in the output file.

To see list of keyboard commands, hit h or ? in the editor.
