Print current expression in GDB

Each time I am with n , it prints the next statement to be executed.

How to see the next statement that will execute as if I typed n , but without actually entering the code?

I am currently using where , and this gives me the line number of the next statement, and I can use list to see some source code. Does it require two separate commands?

Define yourself macro in your .gdbinit in your home directory.

 define shownext where list end

Well, I'm not sure what I said works, but see here how to do it.

Try the "frame" command. You will see something like this:

  (gdb) frame #0 main () at dummy.c:11 11 FILE*f = fopen("somefile","r"); (gdb)

If your gdb was built with Python support, this list.current.py script will add a new list, the current gdb, which does what you want.

Session Example:

 $ gdb -x list-current.py /bin/true (gdb) start Temporary breakpoint 1 at 0x4014c0: file true.c, line 59. Starting program: /usr/bin/true Temporary breakpoint 1, main (argc=1, argv=0x7fffffffde88) at true.c:59 59 if (argc == 2) (gdb) list-current 59 if (argc == 2) (gdb) list-current 3 59 if (argc == 2) 60 { 61 initialize_main (&argc, &argv); (gdb) list-current -2 58 argument. */ 59 if (argc == 2) (gdb)
