Re: Common History across Shell

I am looking for a feature where if a user has multiple shells and on
a special keystroke / command all shells get a common history which is
sum of all histories.

Does such a feature exist in bash or any other shell?
Can such a feature be implemented without changing the shell's code?

zsh¹ can share its history among multiple instances of the shell. See
'SHARE_HISTORY' and 'INC_APPEND_HISTORY' in 'man zshoptions'. Manual
importing is possible as well via the 'fc' builtin (which can be bound
to a keystroke, if that's desired).

Note, that I don't use this feature, so I don't know how well it
works. But I know people who do use it, and I didn't hear of
particular problems.

Regards, Frank
