title: how to automate timed running of 2 programs?
body: <p>I'm working in linux. I have two programs that run for infinite time ( that is , wont stop unless i kill the process ).i want to run program 1 first and then run program 2 after 20 seconds ( both will have to run simultaneously as one reads a file written by the other ).Currently , i am running the 2 programs by manually keeping track of time.. Is there a way to automate this ? i.e. is there any command or can any program be written to do this..</p>
