Is there an environment variable in bash that can be used to tell where bash is running from? For example, is there a variable I can test in my .bashrc to tell whether I am running remotly, from a tty, from konsole, an xterm, etc.? I'v looked at the Advanced Scripting HOWTO, but the only thing that looked promising was "$BASH_ENV" which seems to be empty.
Thanks, -Dan
