How to map (alias?) a command in vim

Question

Lets say, hypothetically, that I always forget the command :vsplit , and always think it's :vdivide .

Is there a way to map (I'm not sure if that'd be the right thing to call it, since it's a command) one to the other?

Answer 1

User defined command can only start with an uppercase letter, so you can only add :Vdivide but not :vdivide .

Add in your .vimrc

 command Vdivide vsplit

Answer 2

To get around the limitation that user-defined commands must start with an uppercase letter, I recommend the cmdalias.vim - Create aliases for Vim commands plugin. With it, you can do:

:Alias vdivide vsplit
