I'm running Ubuntu 9.1 and every time I open a terminal window, I lose the previous command's history. How can I configure it so it's kept even after rebooting?

What are the permissions on ~/.bash_history? Can your user modify it?

Alternatively, are you exiting out of the previous window first?

  • Bingo!, for some reason it was owned by root. Thanks!

I'm assuming you're using Bash.

Try this command at Bash prompt:

shopt -p histappend

If it says:

shopt -u histappend

then add this line in your ~/.bashrc:

shopt -s histappend

  • The output of "shopt -p histappend" is "shopt -s histappend"

    Make sure you exit from Bash cleanly (e.g. with the exit command). Bash only updates .bash_history on a clean exit, so if the process dies unexpectedly (e.g. reboot, closing an xterm), it may not have a chance to update the file.
