If you want to port such a project: Start by moving code into bash functions if it's not already doing that. Declare variables with `local` to reduce the amount of global state. Once you have code in functions, you can factor code into independent scripts. Anything that runs in a subshell can move into its own script, so anything: 1. in a pipe | line 2. running in the background& 3. in a ( subshell ) 4. that doesn't modify global variables You can then work on those scripts piece by piece.
