Environment variables passed by Runtime.exec(String)

原文 2010-12-02 12:54:24 9 1 java

Are the environment variables of the parent process(eg shell) available in the environment in which a child process that is invoked using Runtime.exec(command) run? I had a look at the API documentation but it's not specified there.

My use case is this

mainScript.sh invokes java MainClass

MainClass invokes Runtime.exec("hi.sh")

Now, is a variable MY_ENV that is set and exported in mainScript.sh available to hi.sh ?

PS: I'm aware of the 2nd API that takes explicit String[] envp .

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4064912 has some vague info.

Yes, why not?

From Runtime documentation :
