lol thanks for the warning. I really appreciate your post. That was valuable to know. I'll def be careful of using dev/null and using dd (data destroyer). I'm currently using virtual machines for Linux practices.
I'm learning to do some CTFs. I noticed that the writer always type this command line
find / -name [filename.txt] 2>/dev/null
I understand what the "find" command line does, but why would he/she add "2>/dev/null"
