redirect - Gdb print to file instead of stdout

Question

I am running gdb and want to examine one of those unfortunate god objects. It takes many pages (and I have a 24" monitor turned sideways!) to see the whole thing. For ease of use, I'd like gdb to print the object to a file instead of the screen so that I can open it in vi and move around with ease. With all gdb's versatility, there must be a way to do this, right?

Answer 1

You need to enable logging.

(gdb) set logging on

You can tell it which file to use.

(gdb) set logging file my_god_object.log

And you can examine current logging configuration.

(gdb) show logging
