okay.... king of stupid questions has a new question. When I open a terminal I always thought the shell I was running was bash. http://www.interworx.com/community/alternative-shells-for-linux/ says that in reality it is Dash. "If you’re running a Debian version later than Squeeze, or one of its derivatives, including Ubuntu, then you’re likely already using Dash, as it’s the default for those distributions. " How do I verify this? And does this mean that there is no need to worry about the Bash vulnerability that was recently discovered? http://arstechnica.com/security/2014/09/bug-in-bash-shell-creates-big-security-hole-on-anything-with-nix-in-it/
