在post-receive鉤子中獲取refname

Question

我在窗口中使用git，並且我想在每次push後做一些操作，所以我使用post-receive hook，但是當我試圖讓refname知道推送的分支時，我給任何東西。

爲什麼？ （我不能也給其他參數：oldrev和newrev）

這是我的後收到的文件，電子郵件被正確發送，但沒有在這一主題的refname（它如果我把$3相同在體內）

#!/bin/sh 
# 
# An example hook script for the "post-receive" event. 
# 
# The "post-receive" script is run after receive-pack has accepted a pack 
# and the repository has been updated. It is passed arguments in through 
# stdin in the form 
# <oldrev> <newrev> <refname> 
# For example: 
# aa453216d1b3e49e7f6f98441fa56946ddcd6a20 68f7abf4e6f922807889f52bc043ecd31b79f814 refs/heads/master 
# 
# see contrib/hooks/ for a sample, or uncomment the next line and 
# rename the file to "post-receive".

在腳本頂部的註釋顯示正在傳遞和如何：

It is passed arguments in through 
# stdin in the form 
# <oldrev> <newrev> <refname> 

關鍵字是stdin。這些不作爲參數傳遞給腳本。

您可以使用類似下面從標準輸入讀取：

while read oldrev newrev refname 
do 
    # Do what you want with $oldrev $newrev $refname 

done
