Bash History

Hello,

I'm working on getting a Gentoo system up and running and the one problem I'm having is that my command history does not seem to get saved. When I boot and then input commands, I can cycle through anything that I used after I booted, but nothing from a previous session. Right now I am logging in as root. Does anyone have a suggestion for how I could get my command history preserved from one login to the next? thanks.

AFAIK bash reads .bash_history when opened, buffers the new one and writes back when it is closed. This might be confusing if you open multiple shells.

Moved from Installing Gentoo.

Yes, I do have the .bash_history in /root, but it also appears in /. The permissions for both of the files is -rw-------. I'm logging in as root, but I'm not sure which one of these should be used. Also, what does it mean when you write ~/ in front of the filename? Does the ~ just represent whatever path may apply to the situation?

As an update, I looked at the contents of both files mentioned above and the one in the / directory is full of commands from a few days ago while the one in the /root directory has only one command that was used a couple of hours ago. This is very strange since I have input many commands since this time. It seems that something is very wrong........

~/ points to your home dir (cd ~/ will cd you into your homedir.. ) Does it work normally for your normal user?

Yes it does work normally for my regular user. Furthermore, I've determined that the history is saved for root if I issue the logout command but not when I use reboot or poweroff. Am I doing this wrong?

Replying to your earlier question, a construction such
as "~tux/" refers to the home directory of user "tux" (which is
likely to be "/home/tux/"). In contrast, "~/", I believe, refers
to the contents of the HOME environment-variable, and will be
fouled-up if HOME is mis-set.

I have the same problem.
There is a /.bash_history full of commands, but my own at /root/.bash_history is empty. cd goes to /root (as user root).

How do you login to root. Do you use su or su -. If you use just su then the root variables are not set and therefore it will probably not able to find your .bash_history.

So try
