ohmyzsh: No, I dont want share history.

Well, you could check the zsh documentation for a start… http://zsh.sourceforge.net/Doc/Release/Options.html

setopt no_share_history or unsetopt share_history

this solved the issue for me:

$ cat ~/.zsh_profile
unsetopt share_history

Agreed. This is driving me nuts. I have many terminals into many servers and the commands from each (usually ssh commands) are all getting mushed together. I now regularly go back to bash because this irritates me so. Please make the default match other shells!

https://github.com/ohmyzsh/ohmyzsh/commit/23760228908d14a4644718869d5ebfb7b0dde6a7 removed share_history from OMZ. Just omz update.

Rant: Can we warn people before doing breaking changes like this one? I have used the zsh shared history feature for years (it’s one of the things I like most about zsh) and to have it turn off suddenly and without any warning is quite disruptive.

Why is this a default? Nothing else does this and there’s not even a use-case for this…

Agreed with others that this option should default to false. It is not consistent with the convention of other shells.

Perhaps it should be disabled by default (it’s not the default for bash on MacOS).

No luck, tried both at the very end of my ~/zshrc:

unsetopt share_history
setopt no_share_history

Hello everybody! Is it possible to leave this option commented? I mean, if somebody (like me) wants to disable the history sharing, it’s only a matter of uncomment the lines.

It’s the third time this hits me, and the third time I have to search internet because I forgot the option 😛

I can do a PR if you agree.

It should be .zshrc where you put this. Then restart all open shell sessions.

Exactly: Oh My Zsh sets the share_history option, so you have to unset that after OMZ has been loaded. I’ve updated the original post to contain the clear solution.

This did not work for me. I have tried both of these in my .zshrc: unsetopt share_history setopt no_share_history I also created a .zsh_profile with the same lines above which still had no affect.

I had to do as OP suggested and delete the line in .oh-my-zsh/lib/history.zsh (which I guess will be undone in the next update)

Could this be an environmental difference? I’m running iTerm2 on OSX 10.10.5

Was surprised to see shared history after changing from zsh to ohmyzsh. Since I tend to have multiple open terminals, each running a different process, sharing history doesn’t fit too well with my workflow.

confirmed,zsh 5.7.1 version,share history command removed

## History wrapper
function omz_history {
  local clear list
  zparseopts -E c=clear l=list

  if [[ -n "$clear" ]]; then
    # if -c provided, clobber the history file
    echo -n >| "$HISTFILE"
    echo >&2 History file deleted. Reload the session to see its effects.
  elif [[ -n "$list" ]]; then
    # if -l provided, run as if calling `fc' directly
    builtin fc "$@"
  else
    # unless a number is provided, show all history events (starting from 1)
    [[ ${@[-1]-} = *[0-9]* ]] && builtin fc -l "$@" || builtin fc -l "$@" 1
  fi
}

# Timestamp format
case ${HIST_STAMPS-} in
  "mm/dd/yyyy") alias history='omz_history -f' ;;
  "dd.mm.yyyy") alias history='omz_history -E' ;;
  "yyyy-mm-dd") alias history='omz_history -i' ;;
  "") alias history='omz_history' ;;
  *) alias history="omz_history -t '$HIST_STAMPS'" ;;
esac

## History file configuration
[ -z "$HISTFILE" ] && HISTFILE="$HOME/.zsh_history"
[ "$HISTSIZE" -lt 50000 ] && HISTSIZE=50000
[ "$SAVEHIST" -lt 10000 ] && SAVEHIST=10000

## History command configuration
setopt extended_history       # record timestamp of command in HISTFILE
setopt hist_expire_dups_first # delete duplicates first when HISTFILE size exceeds HISTSIZE
setopt hist_ignore_dups       # ignore duplicated commands history list
setopt hist_ignore_space      # ignore commands that start with space
setopt hist_verify            # show command with history expansion to user before running it

if you need shared history command,you can add command to .zshrc file or add command to ~/.oh-my-zsh/lib/history.zsh file

setopt inc_append_history     # add commands to HISTFILE in order of execution
setopt share_history          # share command history data

execute command

source ~/.zshrc

use unsetopt SHARE_HISTORY

in your .zshrc file

Sorry, I misread your comment. Did you append that at the end of the file?

share_history has not been removed, macOS still have the setop flag, 😦

@mcornella @robbyrussell, I see this issue as well. I tried appending the unsetopt share_history at the bottom of .zshrc and still same issue

It might in the future, why not just add it to the .zshrc file (after OMZ is sourced)? It’s much more portable and cleaner.

vim ~/.oh-my-zsh/lib/history.zsh

remove command

setopt inc_append_history setopt share_history

or in .zshrc file add command

unsetopt inc_append_history
unsetopt share_history

I notice from the docs that it says:

INC_APPEND_HISTORY_TIME

This option is a variant of INC_APPEND_HISTORY in which, where possible, the history entry is written out to the file after the command is finished, so that the time taken by the command is recorded correctly in the history file in EXTENDED_HISTORY format. This means that the history entry will not be available immediately from other instances of the shell that are using the same history file.

This option is only useful if INC_APPEND_HISTORY and SHARE_HISTORY are turned off. The three options should be considered mutually exclusive.

…

SHARE_HISTORY <K>

This option both imports new commands from the history file, and also causes your typed commands to be appended to the history file (the latter is like specifying INC_APPEND_HISTORY, which should be turned off if this option is in effect). The history lines are also output with timestamps ala EXTENDED_HISTORY (which makes it easier to find the spot where we left off reading the file after it gets re-written).

Is it intentional that INC_APPEND_HISTORY and SHARE_HISTORY are both set in oh-my-zsh?

@JohnnyWalkerDesign, I’ve a created an issue on StackOverflow which better illustrates, what i’n truing to achieve: https://stackoverflow.com/questions/48873643/how-to-stop-zsh-from-merging-history-for-all-closing-tabs

@mcornella Oh thank you for the tip. It was the ordering. This was driving me nuts. 🌻
