无论出于何种原因，zsh不喜欢我为我的$EDITOR变量设置命令行参数，但从我所知道的，它不应该是这样的。我见过人们使用
export EDITOR='open -Wn'
zsh: command not found: open -Wn
出现这种情况的原因是什么？将$EDITOR设置为'mate'，'vim'或'open'似乎工作得很好，但'mate -w'和'open -Wn'不起作用。

在zsh中，当您编写$EDITOR时，它会扩展为单个单词。与其他Bourne样式的shell不同，zsh在扩展未引用的扩展时不会拆分单词。你可以用它来实现它
= modifier on parameter expansion
$=EDITOR $file
更便携的方法是确保EDITOR不包含任何空格。大多数应用程序将$EDITOR视为shell片段或以空格分隔的单词列表，但我遇到过一些将其视为命令名称的应用程序。使EDITOR指向shell脚本。
% cat ~/bin/EDITOR
#!/bin/sh
open -Wn -- "$@"
% grep EDITOR ~/.profile
export EDITOR=~/bin/EDITOR
答案 1 :(得分：3)
你是如何援引编辑的？如果您为EDITOR设置了选项，那么您将收到错误：
$ $EDITOR file
但如果你这样做，它应该有效：
$ eval $EDITOR file
答案 2 :(得分：2)
调用$EDITOR定义的编辑器的程序可能会假定它引用的整个字符串是命令的名称。因此，他们将尝试查找名为open -Wn的可执行文件。
另一个问题是open只是打开文件，其中包含操作系统认为合适的应用程序。如果没有与文件类型关联的应用程序，则命令将失败。
