Specifically, I want to run
webpack --progress --color -w
Which are both long-running processes. I want to see the output from both, interlaced in my terminal. It doesn't matter if the results are a bit jumbled, I just like to see that they're doing what they're supposed to.
Also, I want it to kill both processes when I press
parallel ::: 'lsyncd lsyncd.lua' 'webpack --progress --color -w'
which seems to be working, but I can't see any output even though when I run those commands individually, they output something.
