如果它们是一个接一个的，那么它就会忽略它们，histignoredups但据我所知，我的配置应该忽略任何一个和全部。

第二个问题：我应该选择~/.zshrc还是~/.zshenv？

答案1

将以下行添加到您的~/.zshrc文件中以避免历史记录中出现重复

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

答案2

修剪所有重复项所需的唯一选项是histignorealldups，并且您已经设置了它，所以是的，正在删除重复项

但从记忆里

您正在查看存储在文件 ( ) 中的历史记录cat $HISTFILE。

如何重现

启动一个新的 zsh 实例，删除所有历史记录并执行一些命令

% 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，您可以设置该选项histignorealldups，所有重复项都会消失（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。

我建议你不要这样做，因为历史可能是这样的共享由多个并行运行的 zsh 实例组成。这不是一个小问题。
