How to use javas Process.waitFor()?

Question

I am trying to run command line commands from Java and a quick sanity check made me realize that the reason I am having trouble is that I can\'t get the pr.waitFor()

Answer 1

You are trying to execute shell commands. You should try to execute a program.

As shown in Femi's answer you could invoke bash as the executable and then pass to it arguments that will have bash execute the sleep and echo command.
