10.4.3. Recording a gdb Backtrace Session

Once you have captured the core file, you can view its contents by using gdb, the GNU Debugger. To record a script session of gdb on the core file from the affected system, run the following:
$ script /tmp/gdb-rgmanager.txt
$ gdb /usr/sbin/rgmanager /tmp/rgmanager-.core.
This will start a gdb session, while script records it to the appropriate text file. While in gdb, run the following commands:
(gdb) thread apply all bt full
(gdb) quit
Press ctrl-D to stop the script session and save it to the text file.
