我想运行Git，根据博客的建议，我使用$git init来初始化仓库，然后创建了一个.git文件夹，在hooks目录中存在钩子。然后按照脚本建议，我将pre-commit.sample重命名为pre-commit，但它没有起作用，所以我将其重命名为pre-commit.sh，但它似乎仍然没有在后台运行或者至少我不知道它是否在运行。
因此，为了知道它是否在后台运行，我使用了echo语句，但是它从未显示过。感到困惑，接下来我尝试在powershell中手动运行脚本.\pre-commit.sh，但echo语句没有在控制台上打印出来。首先，我不知道即使用户通过输入反馈来阻止脚本的进度，控制台是否会显示echo语句是否成功。
那么，请告诉我如何设置预提交钩子？我是否误读了该过程？我错过了什么吗？请让我知道。
我正在使用一个默认的预提交钩子实现，只是为了方便，我在这里放置它 -- 希望它能帮助到您：

# An example hook script to verify what is about to be committed.

# 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

# 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 --
