About
- gVim has a Graphical User Interface (GUI) - The gvim command causes the editor to create a new window for editing. gvim you have extra features, like a menu bar.
- vim: the editing occurs inside your command window. In other words, if you are running inside an xterm (or MS-DOS command prompt), the editor uses your xterm window (or MS-DOS command prompt). Vim is a descendant of vi.
If you got strange behavior, you may have Vim configured to work Vi compatible.
