Normally, typing edit on a Unix system brings up the vi editor and not Vim. If you've installed Vim in your home directory somewhere, you don't have a root account, and you want to make Vim the default editor for anything you do (e.g. edit a SQL statement in SQLplus), define these three variables in your .profile:
VIM=<base directory where Vim executable is placed> VIMRUNTIME=<base directory where Vim runtimes are kept> EDITOR=$VIM/vim
If you've installed vim with another name (say, vim.exe) then change EDITOR=$VIM/vim to EDITOR=$VIM/vim.exe
Source .profile, and the next time you start an editor from any program you'll bring up Vim.
On Ubuntu (or other Debian-based systems), update-alternatives can be used to change the default editor:
sudo update-alternatives --config editor # Type the number which corresponds to Vim here (after installing it) then press Enter.
$EDITOR is the defined variable that programs on Unix-like operating systems are supposed to use for the default editor. Actually, $VISUAL is another defined variable for a non line-oriented editor, which is technically the correct role for Vim. Many notable programs on Unix support these variables, though obviously there are a few that for various reasons do not.
