If your command is just a shell command, you could run your command in a subshell like this:
如果您的命令只是一个 shell 命令，您可以在子 shell 中运行您的命令，如下所示：
( . .env ; echo "$TEST" )
The sourceor .builtin has no problem with assignments containing spaces. It will set the variables in the .envfile in the current shell's environment.
该source或.内置有包含空格的任务没有问题。它将.env在当前 shell 的环境中设置文件中的变量。
In the more likely case of calling an external program, you'll also have to add 'export' to each assignment in your envfile like this:
在更可能调用外部程序的情况下，您还必须为env文件中的每个分配添加“导出”，如下所示：
export TEST="hello world"
This is necessary because sourcedoes not export assigned variables as envdoes, i.e. they are set inside the subshell only but not in the environment of another process started inside that subshell.
这是必要的，因为source它不像那样导出分配的变量env，即它们仅在子外壳内设置，但不在该子外壳内启动的另一个进程的环境中。
