Backgrounds
DESCRIPTION
While 'run -bg' and 'runXX -bg' commands can only run executables in background, bgs (aka backgrounds) can run script excerpts in the background parallelly. Hence, they are a much more flexible way of a concurrent/parallel execution than the 'run* -bg' commands. Backgrounds (::pwtk::bg) are also safer to use than threads (::pwtk::thread)
