Iterating a list of files should be handled by built in support for lists on language level and listing files from the stdlib, not based on your personal preference that spaces in strings is a universal delimiter for list-items because ls in some happy-cases happen to print files that way. What are you going to do next time you have to iterate any other type of data with spaces in it? Claim that's complex too? Trying to shoehorn in arbitrary restrictions to data identifiers because of the way it's serialized in some situations just leads to the "csv-problem" where you never reach a uniform standard because some prefer using spaces as separators, some use tab, some use comma, semicolon, quotes are always allowed, etc... Just define a standard array-type once and for all and use it to pass data for everything. Take python for example os.listdir() is just one call away, same for any other high level language. (I am aware bash already has this and one should use globs instead of ls, though i wouldn't advocate bash for anything regardless, for multiple other reasons)
