Zsh 想要自动更正命令，在它之前有一个 _ [英] Zsh wants to autocorrect a command, with an _ before it

问题描述

我最近才开始使用 Zsh 来为我的 Git 状态等在 shell 提示中提供一些集成支持.

I just started using Zsh lately for some of the integrated support in the shell prompt for my Git status etc.

当我输入时:

 ruby -v

为了确认我正在运行的 ruby​​ 版本，Zsh 询问我是否要将命令更改为 _ruby.在提示符下说不"并且命令按预期完成后，在确认我的命令正确后，我继续在提示符下收到问题.

to confirm the version of ruby I'm running, Zsh asks if I want to change the command to _ruby. Well after saying no at the prompt and the command completing as expected I continue to get the question at the prompt after confirming my command is correct.

我假设有一个完成文件或类似的东西.

I'm assuming there is a completion file or something of the sort.

谢谢

更新:

外壳不再尝试完成 _ruby，它在关闭外壳几次后停止响应.

The shell is no longer trying to complete _ruby, it stopped responding after closing the shell a few times some how.

我多次尝试清理文件，但有一个opts"变量长达 50 行或更多行，并且所有行都运行在一起，有些行超过 150 个字符.如果你还想看的话，我可以给你发个附件.对于这篇乱七八糟的帖子，我深表歉意.

I tried to clean the file up several times but there is a "opts" variable that is 50 or more lines long and the lines are all ran together, some lines more than 150 characters. Maybe I could email an attachment to you if you still want to see it. I sincerely apologize for the messy post.

推荐答案

这是命令自动更正，由 correct 选项激活.它与完成无关.您看到 _ruby 是因为 zsh 认为没有 ruby 命令并且它提供 _ruby 作为最接近的现有匹配.

This is command autocorrection, activated by the correct option. It has nothing to do with completion. You're seeing _ruby because zsh thinks there is no ruby command and it offers _ruby as the nearest existing match.

如果你刚刚安装了 ruby，可能 zsh 之前已经记住了可用命令的列表，它不会总是尝试查看命令已经出现在两者之间.在这种情况下，运行 hash -rf.以后的 zsh 会话不会有这个问题，因为 ruby 命令在它们开始时已经存在.

If you've just installed ruby, it's possible that zsh has memorized the list of available command earlier, and it won't always try to see if the command has appeared in between. In that case, run hash -rf. Future zsh sessions won't have this problem since the ruby command already existed when they started.

有时，当您更改 PATH 时，zsh 会忘记一些散列命令.选项 hash_listall 有助于解决这个问题.如上，如果您可以使用 hash -rf 强制 zsh 刷新其命令缓存.

Sometimes, when you change your PATH, zsh forgets some hashed commands. The option hash_listall helps against this. As above, if you can force zsh to refresh its command cache with hash -rf.
