Heh.. don't worry abt stackdump its the stackdump file of of a.exe,
with whom I am going to swap the content. b.exe was the temporary
file. I would suggest go for Ara's solution, I jumped the gun a tad
too quickly.

but, before running mine script, please put your actual file names...
in stead of dummy one that I have put for you. Obviously, in your
current directory those files are not there and hence the error:

require 'fileutils'

FileUtils.copy_file("src_file","temp_file")
FileUtils.mv "dest_file","src_file"
FileUtils.mv "temp_file","dest_file"

but if you are planning to use, above code, you will have to make sure
that your program doesn't have another temp_file open with same name.
