+!How can I get a substring of a variable?
+
+Say the variable test contains the string "corndog" but we want just the "dog" part.
+
+echo ${test:4:3} will return just "dog"
+
+The 4 tells us the index of the char that will be the first char in the substring. The 3 tells us how many letters to add starting at the index.
