GDB Commands.txt

Relevant gdb commands I've gathered over time:

info gdb 					//Manual
info locals 				        //Vars in local scope
info variables				//Vars declared outside current scope
info functions				//Names and datatypes of all defined functions

p var 						//Print the value of variable var
p var = value 			        	//Force set value to a var
