post-checkout git hook无法正常工作

Question

我有git checkout hook称为post-checkout

$ 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

结账后的内容是：

#!/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，当我克隆我的回购时，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/

但在克隆和CD到git-maildiff的克隆目录之后，我尝试结帐，我什么都没得到。

$ 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文章post-checkout分支，我会在shell中打印出来的post-checkout。

那么在哪里出错了？

根据documentation post-checkout脚本收到3个参数。我有一个类似的问题，我解决了添加一行来读取这些参数（它们没有被使用并不重要）。该脚本将如下所示：

#!/usr/bin/env bash
read previousref newref flag
echo "Hello from post-checkout"
.....
