GDB With a coredump file in linux

Question

I just got a core-dump file in linux with

ulimit -c unlimited

how can I attach gdb with it

I need to give command line arguments with it.

sample executation:

./my_prog arg

Help me to get into gdb

Cheers!!

I answered but downvoted the question since it is in the GDB documentation which has a nice tutorial. Asking on StackOverflow such basic questions take you more time than reading the start of the documentation.... — Basile Starynkevitch, Apr 13 '13 at 06:26

If your core file is core just run

gdb ./my_prog core

to do some post-mortem analysis with the core.

If you want to use gdb without your core, consider

gdb --args ./my_prog arg

or else run just gdb ./my_prog then issue the set args command to gdb.

If your process is still running as pid 1234, you could with gdb ./my_prog 1234 attach the gdb to the running process.

You really should read the gdb documentation.
