zsh历史太短 [英] zsh history is too short

问题描述

当我在Bash中运行history时，我得到了很多结果(超过1000个).但是，当我运行history zsh shell时，我只会得到15个结果.这使得zsh中的grepping历史几乎毫无用处. 我的.zshrc文件包含以下几行:

When I run history in Bash, I get a load of results (1000+). However, when I run history the zsh shell I only get 15 results. This makes grepping history in zsh mostly useless. My .zshrc file contains the following lines:

HISTFILE=~/.zhistory
HISTSIZE=SAVEHIST=10000
setopt sharehistory
setopt extendedhistory

如何修复zsh以使我的shell历史记录更有用?

How can I fix zsh to make my shell history more useful?

更新

如果在zsh中打电话给history 1，我将获得所有历史记录，就像在Bash中使用history一样.我可以对该命令进行别名以获得相同的结果，但是我想知道为什么history在zsh和Bash中的行为不同.

If in zsh I call history 1 I get all of my history, just as I do in Bash with history. I could alias the command to get the same result, but I wonder why does history behave differently in zsh and in Bash.

推荐答案

NVaughan(OP)已经在问题的更新中给出了答案: history在bash中的行为与在bash中的行为不同zsh :

NVaughan (the OP) has already stated the answer in an update to the question: history behaves differently in bash than it does in zsh:

简而言之:

• zsh :
  • history仅列出 15个最新历史记录条目
  • history 1列出全部-参见下文.
  • zsh:
    • history lists only the 15 most recent history entries
    • history 1 lists all - see below.
    • history列出所有历史记录条目.
    • history lists all history entries.

    可悲的是，将数字操作数传递给history的行为也不同:

    Sadly, passing a numerical operand to history behaves differently, too:

    • zsh :
      • history <n>显示所有条目 以 <n> 开头-因此，history 1显示所有条目.
      • (history -<n>-注意--显示 <n> 最新 项，因此默认行为实际上是history -15)
      • zsh:
        • history <n> shows all entries starting with <n> - therefore, history 1 shows all entries.
        • (history -<n> - note the - - shows the <n> most recent entries, so the default behavior is effectively history -15)
        • history <n>显示 <n> 最新 条目.
        • (bash的history不支持从中列出条目号；您可以使用fc -l <n>，但必须存在特定条目<n> ，否则命令失败-参见下文.)
        • history <n> shows the <n> most recent entries.
        • (bash's history doesn't support listing from an entry number; you can use fc -l <n>, but a specific entry <n> must exist, otherwise the command fails - see below.)

        可选的背景信息:

        • 在zsh中，history实际上(不是实际上)是fc -l的别名:请参见man zshbuiltins
          • 有关许多与历史相关的功能，请参见man zshall
          • In zsh, history is effectively (not actually) an alias for fc -l: see man zshbuiltins
            • For the many history-related features, see man zshall
            • 请参阅:man bash
            • bash:必须存在特定条目<fromNum>.
            • zsh:只要至少有1个条目位于(显式或隐含)范围内，命令就会成功.
            • 因此，fc -l 1在zsh中工作以返回所有历史记录条目，而在bash中通常不会，因为条目#1通常不再存在(但是，如上所述，您可以使用history而不使用参数来列出bash中的所有条目.
            • bash: specific entry <fromNum> must exist.
            • zsh: command succeeds as long as least 1 entry falls in the (explicit or implied) range.
            • Thus, fc -l 1 works in zsh to return all history entries, whereas in bash it generally won't, given that entry #1 typically no longer exists (but, as stated, you can use history without arguments to list all entries in bash).
