I have 10 files in my current directory and there is core dump occurred due to one file only. How do I find this particular file? Is there any command for this in gdb?

The question you probably are asking: there are multiple executables and a core dump. How can I find out which executable produced the core?

Running file core may or may not answer that question (the first 16 characters of program invocation are easily available, but this doesn't work well when the program is invoked with /long/path/to/the/binary).

If you are on a recent Linux, readelf -n core may have NT_FILE note that will list full paths to the binary and all shared libraries.

Otherwise, running strings core usually allows one to guess which program produced it.
