Here are some notes on the GNU Debugger:


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
info b 						//List all breakpoints
break funcName				//Set breakpoint at function funcName (short: b funcName)
break file::line			        //Set breakpoint at line in file
layout next					//Cycle through the layouts of gdb
p var 						//Print the value of variable var
p var = value 			        	//Force set value to a var
run 						        //Start the program
start 						//Synonymous to (b main && run). Puts temporary b at main
next 						//Execute the current line in source (short: n)
step 						//Step into function call at current line (short: s)
finish						//Finish the execution of current function (short: fin)
continue					//Resume execution (After a breakpoint) (short: c)
refresh 					        //Repaint the interface (To fix corrupted interface)
shell cmd 					//Run shell command cmd from gdb prompt
python gdb.execute(cmd)		//Run a gdb command cmd from python prompt
set print pretty on			//Enable pretty printing
							  (Put in ~/.gdbinit)
$ gdb -c core.num			//Examine the dumped core file from a SIGSEGV(shell command)
bt							//Print backtrace
break _exit 				        //Breakpoint at exit of program
whatis expr					//Print datatype of expr
ptype expr					//Detailed print of datatype of expr
watch var 					//Stop when var is modified
watch -l foo				        //Watch foo loaction
rwatch foo					//Stop when foo is read
watch foo if foo>10			//Watch foo conditionally
delete						//Delete all breakpoints
delete breakpoint_no		        //Delete breakpoint breakpoint_no
command breakpoint_no		//Run user listed commands when breakpoint is hit
							  (End list of commands with 'end')
file executable 			        //Load the executable for debugging from inside gdb
quit						        //Quit (short: q)
