MySettings：SomeSetting = MyNewValue
你是如何在Linux中做到这一点的？ export命令拒绝冒号？例如：
export MySettings：SomeSetting = MyNewValue
错误
bash: export: `MySettings:SomeSetting=MyNewValue': not a valid identifier
If : cannot be used in environment variables in your system,replace : with __ (double underscore).
:
__
即：
export MySettings__SomeSetting=MyNewValue
