Core file not generated in Ubuntu 18.04
I was trying to generate a core file in Ubuntu 18.04. My program generates a core file, but I'm not able to find it.
$ ./a.out
Segmentation fault (core dumped)
$ ls -lrt

Since non-programming users can learn little from coredumps, your shell likely suppresses them by default by setting the ulimit
value to zero:
$ ulimit -c
0
You can set the value to any non-zero size, or simply remove the limit altogether using ulimit -c unlimited
See help ulimit
or refer to man bash
for details.
already set ulimit to unlimited
