The command history between sessions is not getting saved. I'm using guake and the history for the session is working fine.

I noticed that .bash_history had some commands I executed in sudo -s mode and tried the same again and all the commands while in the session got saved so I tried:

chmod 777 .bash_history

Now the old commands appear at the start of a session but no new commands are getting saved.

The commands are not visible because Bash saves history to the .bash_history file only after the shell quits, and this happens very rarely with Guake. There is a simple workaround to make Bash append the history (instead of overwriting the file) after every command

shopt -s histappend
PROMPT_COMMAND="history -a;$PROMPT_COMMAND"

Related, typically how this gets broken is if you sudo a command before you have a .bash_history file, as then it'll get created owned by root instead of your user.

See http://mywiki.wooledge.org/BashFAQ/088 for how to avoid losing history lines, and an explanation of the side-effects of doing so.

It could also be that root:root owns your .bash_history (ROOT SHOULDN'T BE THE OWNER, YOUR USER SHOULD BE THE OWNER!), in that case you need to:

#chown user:user .bash_history

This apparently could happen if you do sudo bash alot!
