Basically you can delete core files if you don't want to debug the problem or they are so old, you don't know how to duplicate it.

You might at least save the "ll" value and the output of "ile" for each.

Hi Dattu,
yes you can delete core files.
See,The operating system generates a core file when a signal is not caught by the program. The core file records the state of the program at the time that the fatal error occurred.You can use the debugger to diagnose some run-time errors after a program has aborted and produced a core file.so,if you dont want to dubug a problem you can delete the core files.

Thanks & Regards

Hi Dattu,

Yes,You can delete core files,The HP-UX system writes out a file containing a core image of a terminated process when certain signals are received . The most common causes are memory violations, illegal instructions, floating point exceptions, bus errors, and user-generated quit signals. The core image file is called core and is written in the process's working directory (provided it is allowed by normal access controls). A process with an effective user ID different from its real user ID does not produce a core image.

A slight typo in my response above:
You might at least save the output from "ll" and "file" for each.

And if these are test systems for your developers, they may want to know about them. At least for their applications.
