I've tried hooking to other commands such as echo and it works well. But when it comes to hooking the x command, it fails. Here's the codes inside of my .gdbinit file.
set $pince_injection_failed = 1
set $pince_debugging_mode = 0
define hook-x
if $pince_injection_failed = 1
echo asdf
end
define hookpost-x
if $pince_debugging_mode = 0
echo zxcv
end
I'm aware that gdb doesn't accept aliases of a function for hooking. But x is already a full function isn't it? I couldn't find any aliases for it. I'm also doubting about it because a single character is too short for a command to be
I found the solution thanks to the Mark Plotnick. It seems like another fault of mine, I found out that there was a function that had a misplaced end, so all functions came after that function got ignored by gdb naturally.
define keks
set $lel=0
while($lel<10)
x/x 0x00400000
set $lel = $lel+1
end
Notice the missing end
at the end of while loop
