Emacs Init: Save Command History
save/store minibuffer history
Many emacs commands lets you use ↑ key to use last command or parameter. But after you restart emacs, command history is gone.
You can make emacs remember command history.
Put this in your Emacs Init File:
;; save minibuffer history (savehist-mode 1)
Command history is saved as a file, by default at
~/.emacs.d/history
