problem saving files in pc linux os
I have a strange problem in pc linux os. Whenever I modify and save a file, it automatically creates a backup and saves the file. e.g if I modify test.txt and save it using vim, 2 files are seen -> test.txt and test.txt~
The next time I modify and save, an additional test.txt~~ is created. How do I get rid of the problem?? I am using the default KDE Desktop environment provided with pc linux os.
