How to keep all bash history

Question

I want to keep my duplicates and all commands started with a space. How do I do that? I have no ideas what to do. Last time that I messed with bash nothing worked at all afterwards.

Answer 1

Open .bashrc using your favorite editor, for example:

gedit ~/.bashrc

Then find:

HISTCONTROL=ignoreboth

Change it to:

#HISTCONTROL=ignoreboth

And save the file.

Now duplicated commands and commands started with a space will be saved in your bash history too.
