5.6 Continuing execution

The command finish continues execution up to the end of the current function, displaying the return value:

(gdb) finish
Run till exit from #0  0x08048400 in foo (p=0x40013f98) 
at null.c:15
0x080483d9 in main () at null.c:7
7         return foo (p);
Value returned is $13 = 255

To continue execution until the program exits (or hits the next breakpoint) use the command continue,

(gdb) continue
Continuing.
Program exited with code 0377.

Note that the exit code is shown in octal (0377 base 8 = 255 in base 10).
