Is there a simple way to persist command history in Vim/Neovim?

Question

Is there an option I can switch on the init.vim config file to let me keep command history between vim sessions?

Answer 1

If I get you right, it should be persisted by default.

Use :<C-f> or q: to open command line with command history

Vim command history is kept in viminfo file (:h viminfo). Neovim uses different thing (:h shada).

Answer 2

You can override the default location of shada-file (history) to fix the location of this file by:

set shada+='1000,n/opt/my.shada

You can choose any location for the shada-file. Don't forget to give the user permission to this file:

sudo chown username:username /opt/my.shada

If you want more history, change 1000.
