how to delete core file (file created due to apps crashed)
1. The problem statement, all variables and given/known data:
When looking for corefiles, include any file with core in its name. (Some UNIX/Linux systems add the PID of the process that created the core to reduce the chances of overwriting an already existing core file that might be needed. The above criterion may be just a bit too inclusive, so use the file command to make sure it really is a core file. Now add an additional command line argument -c to the core deletion that you should attempt to add a test that looks for the relevant executable file using a system path, and only deletes the core if the program that crashed is in the path. A program that the user is developing would probably not be in the path and the core file would be retained. This is probably beyond many of your abilities right now. So, the following command will extract the name of the binary which generated the core file :
This is one of many possible starting points to solve the problem. If you have a more succinct way of solving the problem, by all means use it. Note: This only pulls the name of the command from the core, you’ll still need to determine if the binary is in the default path. I have put a sample “real” core file in the directory: /public/courses/UnixEssentials/Assignments/A1 to use for testing.
The requirement here simply asks to find the core file generated by the system binary which has crashed and delete those core file. If the code found a core file generated by a user program, it will ignore it. 2. Relevant commands, code, scripts, algorithms:
as far as I know, the command above will list the name of the binary that generated the core file.
3. The attempts at a solution (include all code and scripts):
as far as I know, the command above will list the name of the binary that generated the core file.
the general steps for solving the problem is
using the above code line to find the core file generated
distinguish the core file generated by the system and the core file generated
by the user program
if the core file generated by the system, delete it, otherwise, leave it intact
I just don't know how to implement this. Please help me, thank u!

I created a bootable CD from Slax and can now access my crashed HD files. Problem is I can't move them to my USB HD even though the device is recognized. From what I have learned, I must "mount" the old HD and the good USB drive and then enter a copy command to permit the transfer (many GB's).

Hi,
Currently, we have a Perl script from a third-party vendor that is generating core dumps. It has been reported. We can't turn off the script as it does generate some diagnostic file that's required. So at the moment, we have to let it continue to do its run.
I wish I can say the vendor is... (8 Replies)
