I realize I may not be as skilled as most current TUs, as I do not know any

Bash is a language =) It has "if" and "for" and functions and variables!
(even if it's not a very good language. Let's say you have the name of
a file you need to remove, stored in a variable? This is how:
rm -- "$VARIABLE"
Every use of a variable must be surrounded in double-quotes unless you
have considered the consequences of splitting it by the value of IFS and
decided this to be safe and desirable. `man rm` explains "--", a
feature which most but not all shell commands offer. And (depending on
your risk model) what if PATH is odd and contains an `rm` binary that
does something else? Robustness/security is always complicated, but
most languages don't have this sort of pitfall =)
