Just wanted to note that this built-in ( $- ) comes in handy for me a lot. It returns all the flags that the shell was invoked with, like: -bash-3.2$ echo $- himBH Basically, that's an interactive shell (i). I find this very helpful in doing checking within .profile or .bashrc files. That way if the shell is invoked interactively, I can set extra variables that wouldn't any sense to add to a non-interactive login, like an ssh command run remotely. Great post, again! Thanks, , Mike Nice post - very easy to read and understand.

Great post, again!
