I am running 12.04 server and when I type history in bash I see most of the commands I have entered into bash but I don't see the commands I have entered when in a tmux session.

How do I see the history of the commands I have run inside a tmux session on Ubuntu 12.04 server after I have ended the session?

So, you want to see the history of the commands that you ran inside tmux in your bash terminal? –  Radu Rădeanu Aug 31 '13 at 17:50
    
If you are referring to the history of bash inside of tmux, and said shell is still running, you will have to add some settings to your ~/.bashrc and ~/.bash_login to make history append to the file while running. –  demure Aug 31 '13 at 22:03
    
@demure I am referring to the history of a bash shell that was inside tmux but tmux and the bash shell that was running in tmux are both no longer running. –  Chris Magnuson Aug 31 '13 at 23:31
    
@RaduRădeanu When I type tmux at bash and get a new bash shell, run ls and then exit, I am now back at the first bash shell and the history command shows that I ran tmux but not that I ran ls. –  Chris Magnuson Aug 31 '13 at 23:33

You have to preserve bash history in multiple bash shells. To do this, be sure that you have the following lines in your ~/.bashrc file:

# avoid duplicates..
export HISTCONTROL=ignoredups:erasedups

# append history entries..
shopt -s histappend

# After each command, save and reload history
export PROMPT_COMMAND="history -a; history -c; history -r; $PROMPT_COMMAND"

I tired this out on 12.04 Ubuntu server and now each time I type the history command my history number increments by 40. I typed history in the shell three times and my last command number went from 1305 to 1345 to 1385 to 1425 and so on. Why is this happening? –  Chris Magnuson Sep 7 '13 at 20:33
    
@ChrisMagnuson This doesn't happen at me. Anyway, this is a different question toward your original question. So, don't hesitate to use Ask Question button. –  Radu Rădeanu Sep 7 '13 at 20:45
