Summary Description

Can we add stack command like pwndbg, which can show more stack.

pwndbg> stack 50
00:0000│ rsp 0x7ffd0042e6a8 —▸ 0x4015d2 (vuln+72) ◂— mov dword ptr [rbp - 0x118], eax
01:0008│     0x7ffd0042e6b0 ◂— 0x0
... ↓        20 skipped
16:00b0│     0x7ffd0042e758 —▸ 0x7fc5e6d7b5c0 (_IO_2_1_stderr_) ◂— 0xfbad2087
17:00b8│     0x7ffd0042e760 ◂— 0x0
18:00c0│     0x7ffd0042e768 —▸ 0x7fc5e6c20525 ◂— cmp eax, -1
19:00c8│     0x7ffd0042e770 ◂— 0x0
1a:00d0│     0x7ffd0042e778 —▸ 0x7fc5e6d7b5c0 (_IO_2_1_stderr_) ◂— 0xfbad2087
1b:00d8│     0x7ffd0042e780 ◂— 0x0
1c:00e0│     0x7ffd0042e788 ◂— 0x0

Thank you for your quick response. Something like this,but not the same. The link given command can only show current stack frame, which stack command of pwngdb can show user specify number memory content of stack from rsp, like this:

In addition, comparing the output of gef and pwndbg, it can be seen that gef's symbol recognition currently seems to only support instruction addresses, while pwndbg's symbol recognition is relatively more comprehensive. For example, in the image, _IO_2_1stderr, because the address of the symbol in gef is data, it refuses to recognize it, while pwndbg can recognize it.

No such work is planned, but feel free to PR it so the team can review it.
