File Format
Name Core dump
Ontology

A core dump file is the saved image of a program's memory state from a Unix-style OS, usually made when it crashes, so that a developer can debug it. The name refers to the days when computers used magnetic core memory for their RAM.

File names are usually just core or start with a prefix of core., depending on system configuration.

[edit] Format

Core files are often in a version or extension of the OS executable file format, such as ELF.

[edit] Specifications

[edit] Software

Core files are usually generated by the OS itself, and can be read by debugging tools for the system they were created on.

In modern Linux environments, those with systemd in particular, core files can be centrally managed as a benefit.
