+# Very essentially getopts allows us to create commands with flags
+# Usually getopts is used in conjunction with a while loop, which takes in a series of flag strings which are expected,
+# it then defines a variable (in this case $opt) which then is used within a case statement to define its behavior
+
+while getopts "ab" opt; do
+    case $opt in
+        a)
+            echo "-a was triggered!" >&2
+            # after we have sent the echo to standard output, we shift the remaining arguments by one so that we can reference them later
+            shift 1
+            # we can of course exit with a success status if we don't want to continue with operations after the -a flag is invoked
+            #exit 0
+            ;;
+        b)
+            echo "-b was triggered also!" >&2

+# this is why we used shift earlier, so to utilize it later in our script after the while loop is done checking our various flags.
