How to create dump files in Linux.

In Linux, the gcore command can be used to generate a dump file. This command creates a core dump file in the specified process, which contains the memory image of the process and can be used for subsequent debugging analysis.

To generate a dump file, you first need to locate the PID (process ID) of the process for which you want to generate the dump file. You can use the ps command to view the list of currently running processes and find the PID of the target process.

Next, execute the following command in the terminal to generate a dump file:

gcore [PID]

“[PID] is the PID of the target process.”

After executing the above command, a dump file similar to “core.[PID]” will be generated in the current working directory, which can be used for further analysis and debugging.
