Keep history of each tab separately even after close and reopen tabby terminal

[Kingdom-Of-Heaven]

I use tabby terminal and want to save history of each tab so every time my history is kept even after close/open. The good thing is when I write something in one tab and something else on another tab is only kept in those tabs means its good. The problem become when I close tabby and open again history of all tabs seems to be merged. How can I avoid that? This is what I have in my ~/.zshrc:

...
  source $ZSH/oh-my-zsh.sh
  
  unsetopt inc_append_history
  unsetopt share_history
  ...

This is unfortunately not possible to do 100% automatically - at the end of the day all history is save into .zsh_history - your options are just delaying this saving until the shell exits so that at least the runtime histories don't overlap.

To have separate histories, you must set separate $HISTFILE env vars for each tab .

Hi, How and where exactly should i separate HISTFILE?

[Kingdom-Of-Heaven]

This way i almost i would want to have:

setopt noincappendhistory
setopt nosharehistory
setopt appendhistory

Each tab doesnt see history of another tabs nevertheless once i close my terminal history is merged. Can u guide me how to change that behaviour?

It's impossible to change unless you make a separate history file for each of your tabs/profiles. ZSH needs to store the history somewhere.
