Git 挂钩。如何从用户输入中读取变量？

Question

我正在尝试创建预提交挂钩。我希望它与用户互动。所以，我发现我可以使用
read -p "Enter info: " info
或者只是
read info

我创建了一个文件：
预提交：

#!/bin/sh
read -r input
echo $input

它只是应该读取变量并输出它。但它不起作用。我的意思是它不能作为钩子。如果我运行它使用带有 ./.githooks/pre-commit 的终端，一切都很好。但是当我使用 git commit -am "Hook" 时，它回显空字符串并且不读取任何内容。我做错了什么吗？

Git 版本为 2.28.0.windows.1

如in this gist, you might need to take into account stderr (used by Git commands, as )

#!/bin/sh
# Redirect output to stderr.
exec 1>&2
# enable user input
exec < /dev/tty

这些行之后的脚本示例：

consoleregexp='console.log'
# CHECK
if test $(git diff --cached | grep $consoleregexp | wc -l) != 0
then 
  exec git diff --cached | grep -ne $consoleregexp
  read -p "There are some occurrences of console.log at your modification. Are you sure want to continue? (y/n)" yn
  echo $yn | grep ^[Yy]$
  if [ $? -eq 0 ] 
  then
    exit 0; #THE USER WANTS TO CONTINUE
  else
    exit 1; # THE USER DONT WANT TO CONTINUE SO ROLLBACK
  fi
fi
