I want to keep history separated for each tab (even for split windows within one tab). I therefore found a solution to add these two lines after source $ZSH/oh-my-zsh.sh:
source $ZSH/oh-my-zsh.sh unsetopt inc_append_history unsetopt share_history Now the history is really separated, nevertheless when I completely close the terminal (in my case Tabby), the histories for each tab are common again. How to solve that? I use zsh with Tabby.
If you want each zsh session to keep a separate history, then you will need to do one of the following:
If you do not want history to be saved to file, then simply unset $HISTFILE in your .zshrc file after sourcing OMZ:
source $ZSH/oh-my-zsh.sh unsetopt inc_append_history share_history unset HISTFILE Then each new shell session will start with an empty history.
If you do want to save history for each session, then you will need to set a different $HISTFILE for each session in your .zshrc file before you source OMZ. If your terminal sets a unique ID for each terminal session (I don't know if Tabby does that), like $TERM_SESSION_ID, then you can do something like this:
mkdir -m 700 -p ${SHELL_SESSION_DIR:=${ZDOTDIR:-$HOME}/.zsh_sessions} HISTFILE=$SHELL_SESSION_DIR/$TERM_SESSION_ID.history source $ZSH/oh-my-zsh.sh unsetopt inc_append_history share_history unset HISTFILE If your terminal persists the $TERM_SESSION_ID for each tab between restarts, then the individual history for each tab will be restored whenever you reopen them.
$HISTFILE parameter. The only way which worked for me with Tabby is to add the following in the .zshrc file:
if [[ -n "$TABBY_HISTFILE" ]]; then export HISTFILE="$TABBY_HISTFILE" fi Then in each Tabby profile set the path for a separate history file by adding a TABBY_HISTFILE environment variable.
For example:
TABBY_HISTFILE = /Users/<username>/TabbyHistory/.zsh_history_profile_a Make sure to re-open the profile in Tabby and run fc -W to force write the new history file.
