Git Hook

背景：并行版本较多，合并至版本发布分支主分支时无法看出初始提交分支

需求：系统开发人员执行git commit时，自动在commit-msg中补充当前所在分支名

操作步骤：

1、在子系统git仓库路径/.git/hooks下，将以下内容覆盖commit-msg.sample文件中

#!/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、去掉文件名后缀.sample使其生效

在git-bash中执行commit操作后，通过git log查看提交记录，此时提交信息已成功生效，显示内容为：<分支名>提交信息
