What is a core file?
What will be an ideal response?
A core file is created when an executing program attempts to do something illegal, such as accessing another user's memory. The UNIX/Linux operating system detects the attempt and sends a signal to the program. The signal halts the offending program, and creates a copy of the program and its environment in a file named core in the current directory. The programmer who wrote the program that "dumps core" (slang for this event) might be interested in dissecting the core file with a debugging tool. However, all too often the core file simply languishes unused in some branch of the directory hierarchy. All files created this way have the same name: core.
