背景：並行版本較多，合併至版本釋出分支主分支時無法看出初始提交分支

需求：系統開發人員執行git commit時，自動在commit-msg中補充當前所在分支名

操作步驟：

1、在子系統git倉庫路徑/.git/hooks下，將以下內容覆蓋commit-msg.sample檔案中

#!/bin/sh
#
# An example hook script to check the commit log message.
# Called by "git commit" with one argument, the name of the file
# that has the commit message.  The hook should exit with non
 
-zero
# status after issuing an appropriate message if it wants to stop the
# commit.  The hook is allowed to edit the commit message file.
#
# To enable this hook, rename this file to "commit-msg".

branch_name=`git symbolic-ref --short -q HEAD`
echo "${branch_name}"
commit="<"${branch_name}">
 
"$(cat $1)
echo "$commit" > "$1"

2、去掉檔名字尾.sample使其生效

在git-bash中執行commit操作後，通過git log檢視提交記錄，此時提交資訊已成功生效，顯示內容為：<分支名>提交資訊
