Vimdiff is a tool that comes bundled with Vim and its a wonderful tool for comparing code and merging changes. Vimdiff starts Vim on two (or three) files. Each file gets its own window. The differences between the files are highlighted. This is a nice way to inspect changes and to move changes from one version to another version of the same file.
vimdiff syntax:-
vimdiff [options] file1 file2
If you want to open files use the following command
vimdiff file1 file2
or
vim -d file1 file2
If you want to open vertical splits for your files use the following command
