      Just to reiterate. Hidden files/directories begin with a period (~/.bashrc). They are "hidden" from normal view so if you type ls or ls -l they won't appear. But if you type ls -la then they are no longer hidden. It's not a security mechanism, it's just to keep things tidy. If you really want to secure something you'll need to change the mode:

      chmod 0600 lakshmana:lakshmana file

      Or set an ACL

      setfacl -m o::- file

      If it's a directory and you want default ACLs you will have to set the default and then apply the ACL.

      setfacl -dm o::- dir/
setfacl -m o::- dir/

        Either use ACLs/Permissions or encrypt your data. You could use an encrypted loopback device (~"image file") for example, but this requires some background knowledge about the underlying technology.

        Gnome has Seahorse built in so you can also use PGP (GPG) keys but I haven't been able to get the Nautilus integration to play nicely. So you can create a PGP key in Seahorse (it will take a little while to have enough entropy and then it will show up) and then encrypt a file with:

        gpg --output <file.gpg> --encrypt --recipient [email protected] <original-file>

        Then decrypt with

        gpg --output <file-to-save-as> --decrypt <file.gpg>

          ACLs are to prevent other users accessing files. Encryption is to stop thieves who steal the drives from accessing them.

            Sure. I suggested encryption because it - depending on the type of encryption (loopback/partiton vs encrypted files) - brings also some obfuscation, for example in backups which are outside of what OP may control.

              I'm not much into *NIX desktop environments. Good to know.

                Ya you're supposed to be able to right click and hit unencrypt or something like that and have it prompt for the password. I haven't been able to get that functionality to work but Seahorse holds PHP keys, SSH keys, passwords, etc. It's not bad.

                  Sure but encryption can act as a type of ACL.

                    Kind of, a shared password kind of ACL.

                      Sure. Same as group based ACLs. But it's only shared if someone else has your password.
