为什么我在我的zsh历史上有副本？

如果他们是一个接一个的像histignoredups但是AFAIK，我的配置应该忽略任何和全部。

第二个问题:我应该选择~/.zshrc还是~/.zshenv？

Answer 1

修剪所有重复项所需的唯一选项是histignorealldups，您已经设置了它，所以是的，重复项正在被移除。

但是from内存

您正在查找存储在文件(cat $HISTFILE)中的历史记录。

如何复制

启动一个新的zsh实例，删除所有历史记录条目并执行一些命令

% zsh -i
% a=( $(setopt) )
% unsetopt $a
% HISTSIZE=0
% HISTSIZE=99
% history
   95  HISTSIZE=99
% setopt INC_APPEND_HISTORY
% ls >/dev/null
% clear
% ls >/dev/null
% history
  113  HISTSIZE=99
  114  history
  115  setopt INC_APPEND_HISTORY
  116  ls >/dev/null
  117  clear
  118  ls >/dev/null

现在，您可以设置选项histignorealldups，所有重复项都将消失(从内存中)：

% setopt histignorealldups
% history
  113  HISTSIZE=99
  115  setopt INC_APPEND_HISTORY
  117  clear
  118  ls >/dev/null
  122  setopt histignorealldups

但这并不意味着这些行已经从历史文件中删除：

% cat ~/.histfile | tail -n 10
setopt INC_APPEND_HISTORY
ls >/dev/null
clear
ls >/dev/null
history
setopt histignorealldups
history
setopt histignorealldups
history
cat ~/.histfile | tail -n 10

要从文件中删除重复项，您必须编辑该文件。

我建议您不要这样做，因为历史记录可能由几个并行运行的zsh实例共享。这不是一个微不足道的问题。

Answer 2

在~/.zshrc文件中添加以下行以避免历史记录中的重复

setopt HIST_EXPIRE_DUPS_FIRST
setopt HIST_IGNORE_DUPS
setopt HIST_IGNORE_ALL_DUPS
setopt HIST_IGNORE_SPACE
setopt HIST_FIND_NO_DUPS
setopt HIST_SAVE_NO_DUPS
