(*
This is a library of functions that use bash shell scripts to accomplish
tasks as fast as possible. Most of these functions can be used by themselves
or be combined with others.
The reason many of them have the runBool parameter (where you can decide
whether or not to have the function run the shell script inside it) is for situations
where you may want to concatenate the functions into a single shell script.
Running them together as a single script is faster than running them
separately, one after the other. For this situation, set runBool to false.
When runBool is set to true, this means the function is intended
to run by itself.
