其他构建工具和技巧
用户启动了一个进程（可以是一个
Java
应用程序、一个构建服务器、一次测试或者任
何其他进程），这个进程将继承你的权限。如果你使用权限很大的用户账户来运行程序，
那么你启动的进程可能会造成很大的破坏！
一个用户可以访问其他组中的其他文件，只要他也是该组的成员并且被赋予了相应的访
问权限。要想在其他组中运行程序或创建文件，你必须运行
newgrp
命令来切换当前组
（例如，
newgrp <group_name>
）。如果你是
/etc/group
文件中
group_name
的成员，则当
前组成员身份将更改为
group_name
。务必要注意的是，切换组后创建的所有文件都将与
新的组关联，而不是与原来的主要组关联。你还可以使用
chgrp
命令来更改组 ：
chgrp
<newgroup>
。
使用文件系统
熟练掌握和理解文件系统，是你需要掌握的最基础的技能。当你登录某台服务器（例如，
一台新的构建服务器）时，通常会直接进入用户账户的主目录（
home
目录）。
浏览目录
主目录是为用户存储文件和创建目录准备的一个目录。如果想要找出主目录与其余文件
系统的关系，你可以使用
pwd
命令。该命令会显示你当前所在的目录，如示例
6-3
所示。
示例6-3：使用pwd命令来查看你当前所在的目录
