A while ago, over some period of time, I found a few related posts on being efficient optimising time management, on both professional and personal levels. Fully going the “optiomal” usually isn’t that a good thing.
Basically, you need slack or idle time. Plenty of it. That improves your agility too.

I needed to enumerate all the parameters to a function and access many of them by index in the same function, so thanks to both these:
I got at this:
declare -a arguments=("$@")
for index in ${!arguments[@]}; do
echo $index/${#arguments[@]}:${arguments[$index]}
done
These are all forms of Array handling or Shell Parameter Expansion with special cases for array variables:
! does indirection, in this case from the array to the index of the array# gets the lengt of the parameter (for arrays: the number of elements)[] acccesse an array variable using an indexVia:
