I am trying Ubuntu Server 10.10 in VirtualBox. I like that the commands I run is saved in a history-file that can be shown with the history command. But if I just turn off VirtualBox without the shutdown command, then next time when I boot, the commands from the last session is not saved in the history file.The commands are only saved if I shutdown the machine with the shutdown command. E.g. shutdown -P 0.Is there any way I can save the history file after every command so they are persistent even after a non-clean shutdown?
How to get a persistent history-file even after a non-clean shutdown?
command line;bash;command history;shutdown
You should always use shutdown.You can add this to your ~/.bashrc file:PROMPT_COMMAND='history -a'This will append the in-memory history to your history file after each command is completed.
