Mangos restarter with GDB

[Guest]

Do anyone have a mangos restarter which starts mangos with gdb (and restarts it with GDB as it crashes)

And ofc save logs.

Would like to do some crashfixing ^^

Regards!

I use this (Based on a TrinityCore Restarter script):

restarter:

#!/bin/bash
screen -A -m -d -S restarter ./restarter-bin

restarter-bin

#!/bin/bash

Its maybe a bit outdated (binary names) but it worked nice,

(if you have suggestions or improvements pleas tell me

Wow, seems to be way more awesome then the one i found! A suggestion would be to have a folder called "crashes" and create folders after date/time where you put the crashlogs (auto) so it doesnt gay out being just one big file, and making you miss crashes (in case you have more then one crash issue)

And btw, i already solved my crash issue, but it is great that we collect this kind of tools!
