Screen and history?

I think one bash You peristere history other:
\r
Offer:
1. To add, not overwrite
shopt-s histappend
\r
2. Multi-line command to store one line (optional):
shopt-s cmdhist
\r
3. After each command to dump the history and perechitivay shared history (that is, if you want to be a team of one bash began to appear in the other).
export PROMPT_COMMAND='history-a; history-n'
\r
4. Cosmetics: do not remember the repetition of commands not to save the specified commands
export HISTCONTROL="ignoredups"
export HISTIGNORE="ls:l:ll:[bf]g:exit"

But you always use a screen? Try, for example, to look for cat .bash_history | grep aptitude and compare it with the memory that you installed.

Better just switch to zsh and include:
\r
setopt share_history # share history between multiple instances
\r
then the story will be shared between different Windows.
\r

>> damnerd: And complete you "window", ie, Ctrl+D (or exit, or logout)?
As will have if the 1-3 session, then exit, and if more is Ctrl+D many times, but sometimes, of course, and that happens just reboot. The result (stored't understand how), like, would not be affected.
