GDB - how do i automatically run commands and save output

Question

i'm new to GDB so hope it's a fair question... i would like to run a script with GDB that get a coredump file and save the BT of all threads into a file. my problem is to operate the GDB. i tried:

GDB <exe> <core file> --command = my_script

where my script is:

thread apply all bt

that doesn't work of course.

is there another way to operate GDB with a certain command? thanks alot

Yes, do not put spaces around the =.

gdb <exe> <core> --command=my_script

Alternatively, just do this:

gdb -ex 'thread apply all bt' <exe> <core>
