我有一个叫做post-checkout的git checkout钩子

$ ll  /usr/local/Cellar/git/2.3.5/share/git-core/templates/hooks/post-checkout 
-rwxr-xr-x  1 root  wheel  375 Aug 13 14:11 /usr/local/Cellar/git/2.3.5/share/git-core/templates/hooks/post-checkout

结帐后的内容为：

#!/usr/bin/env bash
echo "Hello from post-checkout"
# Delete .pyc files and empty directories from root of project
cd ./$(git rev-parse --show-cdup)
# Clean-up
find . -name ".DS_Store" -delete
NUM_PYC_FILES=$( find . -name "*.pyc" | wc -l | tr -d ' ' )
if [ $NUM_PYC_FILES -gt 0 ]; then
    find . -name "*.pyc" -delete
    printf "\e[00;31mDeleted $NUM_PYC_FILES .pyc files\e[00m\n"
fi

所以当我克隆我的repo时，我将模板的路径传递给模板标志，如下所示：

$ git clone  https://[email protected]/sanfx/git-maildiff.git --template=/usr/local/Cellar/git/2.3.5/share/git-core/templates/

但是在我克隆并CD到git-maildiff的克隆目录并尝试 checkout 之后，我什么也没有得到。

$ git clone  https://[email protected]/sanfx/git-maildiff.git --template=/usr/local/Cellar/git/2.3.5/share/git-core/templates/
Cloning into 'git-maildiff'...

$ git checkout
Your branch is up-to-date with 'origin/master'.

但是如果我运行我的可执行post-checkout分支，我会得到在shell中打印的Hello from post-checkout。
哪里出了问题？
