It's been 2 days with linux and I'm growing a lot into it. Some commands are easy to get by some are not. Some troubles I have right now are compiling sources, but I get by it with time. Anyway to my questions:
Is there a specific command that I can type to delete all of my logs/keystrokes at the terminal without destroying any files? Is there even a such file, folder, or directory that stores all keystrokes/syntax commands that I type at the terminal?
If you ask why I asked this question?
Because I'm concerned about the security. Take for example, when you're a user and you want to delete a file or directory, you have to login as root. In order for that to happen, you have to go into the terminal and type in the syntax command "su" then the password to get the rights. Where does that information go? Is it possible that maybe the information is stored somewhere in a file, folder, or directory? If not, then cool I guess.
The thing is, if there IS a such file or folder somewhere that stores every syntax command I type at the terminal, I would gladly like to know about it so that I can delete it or clear it up at every terminal session without leaving a trace behind.
I have read that linux is open source. So in a way, that tells me that there has to be a file somewhere that stores all the information I type at the terminal, right? No?
