不过，有时候可能会希望在命令失败时即停下，因为继续执行会带来更大的损害。
However, there are times when you want to stop the moment a command fails because continuing could be more damaging.
需要对其他的环境变量进行导出、或使得它们全局可用，并将它们复制到从命令行中启动的每个命令的进程空间(即环境)。
Other environment variables are exported, or made globally available, and are copied into the process space (the environment) of every command you launch from the command line.
