Print a backtrace of the last failed command

bt.sh

#!/bin/bash

# Save into /usr/local/bin/bt and make the file executable. On Ubuntu you may 
# need to additionally perform the following:
#
#    sudo apt install systemd-coredump
#
# Calling `bt` then non-interactively prints a backtrace of last program that
# exited with a SIGABRT or SIGSEGV. Makes use of systemd's builtin coredumpctl,
# causes no core files littered around on the filesystem.

coredumpctl debug -q -A "-iex \"set pagination off\" -iex \"set style enabled on\" -iex \"set debuginfod enabled on\" -ex bt --batch"
