gdb-expeda$ editor tmp.py # You must have set `$EDITOR` . And you can use `vim` or `emacs` instead of `editor` .
gdb-expeda$ cat tmp.py
while True:
    c.next() # You can use `p` and `c` suddenly if you have used `p = PEDA()` and `c = PEDACmd()` in `gdbrc.py` .
    eax = p.getreg("eax")
    if eax == 0:
        break
