  3. # This is a linux log file eraser. It doesn't just clean
  4. # certain data out of the logs - it securely deletes them
  5. # with the shred tool (which must be installed).
  6.  
  7. # There are no arguments to pass to this script, just run
  8. # it with elevated privledges and it will securely wipe every
  9. # log you have (but feel free to add more logfile locations)
  10.  
  11. # Note: I am not a python programmer, I just needed a script
  12. # to do this, so please use eye bleach once you're done reading
  13. # the code.
  14.  
  15. # This wouldn't have been possible without the help of tekwizz123
  16. # to tell me how to python. Much props to him.
  17.  
  18. # I take no responsibility for any damage this causes, use it
  19. # at your own risk! The first time I tried it, it froze my Kali
  20. # VM, but after that it worked fine. It's also been tested
  21. # successfully on multiple virtual private servers.
  22.  
  23. # If you have questions, comments, concerns or want to tell
  24. # me about more logfile locations, you can email me at
  25. # dex @at@ dexstor.org
