I'm looking for the way to run Stata commands in background. I found the following article, but I would like to do it within Stata.

I mean I would like to run two different programs (commands) at once, not in order. In Bash, we can do so using "&".


If what you're asking is whether you can do something like


    . <first command> &
    . <second command>


at the Stata prompt -- where the second command would begin executing before the first has finished -- the answer is no. If you find yourself spending a lot of time waiting for commands to finish (e.g., because you are working with very large datasets and/or are doing very computationally-intensive analyses), then you probably need to structure your work differently (or, depending on the situation, perhaps consider a hardware upgrade and/or Stata/MP). For example, you can break different tasks into separate do-files, and then run these as separate processes in your OS.
