在 Git 中运行预提交挂钩。有没有办法验证脚本是否正在运行？

我想运行 Git，按照博客的建议，我使用了$git init初始化存储库，然后.git在 hooks 目录中存在钩子的位置创建文件夹。然后按照我重命名的脚本的建议pre-commit.sample as pre-commit它不起作用，所以我将其重命名为pre-commit.sh它似乎仍然没有在后台运行，或者我至少不知道它在后台运行。

因此，为了了解它是否在后台运行，我使用了 echo 语句，但我从未出现。感觉迷失了，我接下来尝试手动运行脚本.\pre-commit.sh在 powershell 中，echo 语句未打印在控制台上。其一，我不知道即使 echo 语句通过使用用户的输入源停止脚本的进度而成功，控制台是否也会显示。

所以请告诉我——如何设置预提交挂钩？我是不是看错程序了？我在这里错过了什么吗？请告诉我。

我使用的钩子是默认的预提交钩子实现，只是为了方便起见，我将它放在这里 - 希望它

#!/bin/sh
#
# An example hook script to verify what is about to be committed.
# Called by "git commit" with no arguments.  The hook should
# exit with non-zero status after issuing an appropriate message if
# it wants to stop the commit.
#
# To enable this hook, rename this file to "pre-commit".

if git rev-parse --verify HEAD >/dev/null 2>&1
then
    against=HEAD
else
    # Initial commit: diff against an empty tree object
    against=4b825dc642cb6eb9a060e54bf8d69288fbee4904
fi

# If you want to allow non-ASCII filenames set this variable to true.
allownonascii=$(git config --bool hooks.allownonascii)

# Redirect output to stderr.
exec 1>&2

# Cross platform projects tend to avoid non-ASCII filenames; prevent
# them from being added to the repository. We exploit the fact that the
# printable range starts at the space character and ends with tilde.
if [ "$allownonascii" != "true" ] &&
    # Note that the use of brackets around a tr range is ok here, (it's
    # even required, for portability to Solaris 10's /usr/bin/tr), since
    # the square bracket bytes happen to fall in the designated range.
    test $(git diff --cached --name-only --diff-filter=A -z $against |
      LC_ALL=C tr -d '[ -~]\0' | wc -c) != 0
then
    cat <<\EOF
Error: Attempt to add a non-ASCII file name.

This can cause problems if you want to work with people on other platforms.

To be portable it is advisable to rename the file.

If you know what you are doing you can disable this check using:

  git config hooks.allownonascii true
EOF
    exit 1
fi

# If there are whitespace errors, print the offending file names and fail.
exec git diff-index --check --cached $against --

首先，您可以添加一个简单的回声。

其次，该脚本将由msys 类似 bash 的 shell https://stackoverflow.com/a/17810334/6309，因此您无法直接从 PowerShell Windows 会话运行它。

第三，确保您确实向索引添加了一些元素，以便 git 提交有要提交的内容（并且预提交挂钩有一个被触发的理由）。

• 它应该重命名为“pre-commit“ 并不是 ”pre-commit.sh" and
• 该脚本确实运行并在命令提示符/powershell 上显示回显语句。
