使用 zsh，我试图在~/.zprofile我以交互方式询问是/否风格问题的地方迈出一步。起初我尝试了这种 bash 风格的方法，但我看到了这种形式的错误：
read: -p: no coprocess
（我知道 zsh 语法通常与 bash 不同——我尝试在它前面加上一个 sh 仿真命令emulate -LR sh——但它没有区别）。
这个页面暗示语法可能不同，所以在这个页面和 zsh 手册页的指导下，我尝试了这个：
read -q REPLY?"This is the question I want to ask?"
相反，这会失败并出现以下形式的错误：
/home/user/.zprofile:5: no matches found: REPLY?"This is the question I want to ask?"
如何用 zsh 问一个简单的是/否问题？理想情况下，该命令只会吞下一个字符，无需按 Enter/Return，并且是“安全的”——即后续测试默认为 no/false，除非输入了“Y”或“y”。
如果第一个参数包含“？”，则该单词的其余部分将在 shell 交互时用作标准错误提示。
你必须引用整个论点
read -q "REPLY?This is the question I want to ask?"
这将提示您This is the question I want to ask?并返回按下的字符REPLY。
如果您不引用问号，zsh则尝试将参数匹配为文件名。如果它没有找到任何匹配的文件名，它会抱怨no matches found.
我添加这个答案是因为每次你想要求用户确认时，你也想对它采取行动。这是一个提示read -q（谢谢，其他答案！）的函数，并在结果上进行分支以执行您想要的操作（在本例中为 git 的东西）：
git_commit_and_pull() {
# http://zsh.sourceforge.net/Doc/Release/Shell-Builtin-Commands.html#index-read
if read -q "choice?Press Y/y to continue with commit and pull: "; then
git add . && git commit -m 'haha git goes brrr' && git pull
else
echo
echo "'$choice' not 'Y' or 'y'. Exiting..."
fi
}
有关 ZSH 读取的文档，请参阅ZSH 手册。尝试：
read REPLY\?"This is the question I want to ask?"
我为此创建了两个实用程序脚本：
read-string.sh从输入中读取字符串（需要用户按回车键）read-char.sh从输入中读取单个字符（不需要按回车键）无论用户使用的是bash还是zsh ，这两个脚本都可以正常工作。
#!/bin/bash
# read-string.sh
# eg: my_string=$(./read-string.sh); echo "my_string: $my_string"

#
# read [-ers] [-a aname] [-d delim] [-i text] [-n nchars]
# [-N nchars] [-p prompt] [-r] [-s] [-t timeout] [-u fd]
# [name...]
#
# -r Do not treat a Backslash as an escape character. The backslash is considered to be part
# of the line. In particular, a backslash-newline pair can not be used as a line continuation.
# Without this option, any backslashes in the input will be discarded.
# You should almost always use the -r option with read.

# [ -u n ] [ name[?prompt] ] [ name ... ]

# don’t quote the following character and are not removed.
if [ -n "$ZSH_VERSION" ]; then
