I have a docker container and every time I build and start it, I want just to press UP for choosing a predefined command.

What's the best way to handle this?

$ echo "<yourcommand>" >> ~/.bash_history

or set up an alias in your .bashrc / .bash_aliases

alias s='<yourcommand(s)>' so every time you input s and hit enter it executes your commands.

  • Thx, I added your first suggestion in my Dockerfile and it works like a charm. It's so simple :) – Centin Mar 11 '16 at 7:47
  • For anyone who wants to keep the command out of the Dockerfile (because you only use it for dev, etc.), you can use bash -c to create the history / add the alias as shown in the answer. e.g., docker run -it ubuntu bash -c 'echo "<yourcommand>" >> ~/.bash_history && bash' – Chris Jul 19 '18 at 2:19

I do: : some_command

Then edit off the colon when I recall it in history. Colon is the null command. It used to be the way to comment things out before the hash became the comment character
