Restoring shell history (experimental)

Supported shells: bash and zsh.

Enable feature with this option in .tmux.conf:

set -g @resurrect-save-shell-history 'on'

Note: the older @resurrect-save-bash-history is now an alias to @resurrect-save-shell-history.

Shell history for individual panes will now be saved and restored. Due to technical limitations, this only works for panes which have no program running in foreground when saving. tmux-resurrect will send history write command to each such pane.

To prevent these commands from being added to bash history themselves, add HISTCONTROL=ignoreboth to your .bashrc (this is set by default in Ubuntu).
