What is GDB?
GDB is a gnu debugger. It will be used to debug the application/program in *nix systems. It is very help full for finding the root caus for the application run time problems. It is available almost in all *nix systems. To use GDB debugger, need to compile the application/program with -g option, so that compiler will create the all symbols for the debugging. GDB will not work if the application compiled without -g option.
GDB commands
gcc -g program-name
