git配置文件读取顺序

  作者：zhanhailiang 日期：2014-11-03

git包含三个配置文件：

/etc/gitconfig 文件：系统中对所有用户都普遍适用的配置。若使用git config 时用‘ –system‘选项，读写的就是这个文件。
~/.gitconfig 文件：用户目录下的配置文件只适用于该用户。若使用git config 时用‘ –global‘选项，读写的就是这个文件。
当前项目的git 目录中的配置文件（也就是工作目录中的.git/config 文件）：这里的配置仅仅针对当前项目有效。每一个级别的配置都会覆盖上层的相同配置，所以.git/config 里的配置会覆盖/etc/gitconfig 中的同名变量。

可以通过git config –list查看当前配置：

[root@~/wade/git/node-lessons]# git config --list
core.repositoryformatversion=0
core.filemode=true
core.bare=false
core.logallrefupdates=true
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*
remote.origin.url=https://github.com/alsotang/node-lessons.git
branch.master.remote=origin
branch.master.merge=refs/heads/master

我们也可以通过strace来检验git配置文件的加载顺序：

[root@~/wade/git/node-lessons]# strace git config --list

由此可以git配置文件加载顺序为/etc/gitconfig → ~/.gitconfig → .git/config，最后加载的同名配置会覆盖前者加载的配置。

经验之谈-MySQL配置文件读取顺序问题！

原因: 用mysql命令可以连上服务端,但通常数据存储在什么地方,参数设置的是什么,这需要知道mysql使用的是哪个配置文件.(通常是my.cnf这个配置问题) 因此需要清除了解my.cnf加载顺序. 默认加载顺序: 路径作用 /etc/my.cnf Global options /etc/mysql/my.cnf Global options (as of MySQL 5.1.15) SYSCONFDIR/my.cnf Global options $MYSQL_HOME/my.cnf Se

cocos2d-x开发: 一切应该从配置文件读取开始

想要做一款完整的游戏,应该从配置文件读取开始.cocos2d-x本身提供了UserDefault来操作xml格式的配置文件,准确的说配置这模块引擎开发者已经考虑到了.但是xml格式包含大量无关的格式信息,对于开发者直接使用编辑器操作也不是很友好.我期望的配置文件应该具备两个特点,第一:格式简单.这是我一贯的*nix风格的要求,我喜欢只管的#注释以及key-value的配置方式.可能唯一需要考虑的是这样简单的配置方式会不会因为业务扩展而显得功能不足.这一点是可以放心的,那些都是业务逻辑相关的,选择

Git配置文件与git config命令

在Git配置文件中配置变量,可以控制Git的外观和操作的各个方面.通过git config命令可以获得和设置配置变量. 一.Git配置文件的位置这些变量可以被存储在三个不同的位置: 1./etc/gitconfig 文件(系统级配置文件):包含了适用于系统所有用户和所有库的值.如果你传递参数选项’--system’ 给 git config,它将明确的读和写这个文件. 2.~/.gitconfig 文件 (用户级配置文件):具体到某个用户.如果你传递参数选项’--global’ 给 git c
