In short, you can use :

  • next to execute the current line and directly go to the next one (if the line is a function call, it doesn't step into the function),
  • step to execute the current line (if it's a function call, it enters the function and stops at its first statement),
  • until X to execute the code and stop on line X
  • b X and then run or continue, to set a breakpoint on line X and execute the code until line X is reached.

If you really want to skip a line, thus stepping to the next one but NOT executing it, you can use jump X (X being a line number). Be careful and use breakpoints, because using jump will make the debugger resume code execution from line X.
