find may be faster if I sent the results into an array or text file and then looped through those results for my program.
My issue with the find command had more to do with the time it took to run to completion. Given the large directory structure and the variety and type of files i needed to search for, the find command took several minutes or more to run to completion.
The particular shell i was writing has a UI, and so the user is forced to wait several minutes or more between executing any search and the ability to work with the results of that search. This was decided to be unacceptable and so a method was needed to execute searches closer to real time and allow the user to interact with files as they are found.
find could still be used the fileScan() function with the prune option to search only within the current directory. But I left the options open in that function to suite your purposes.
So perhaps I overstated the net speed of the functions in relation to find. find may work faster overal, but if a user is faced with waiting for a find command to run to completion vs the abiltiy to interact with the results of a search in near real time, i believe this is a better method.
As for the comment about directory deletion while this script is running, I can see the pitfalls, but it can also be avoided by making subdirectories into a local array and storing the results of an ls there without using the head and tail method. attempts to cd into the non existent directory would be handled in the if [ $folder = $PWD ] logic.
