[LUNI] Remembering which shell (not a good explaination)

[Joe Digilio]

Well, I got intrigued by this question. After a bit of playing around, the 
best way I've come up with so far to tell how deep you are is this:

   ps --no-headers To cmd | grep "^-\w*sh" | wc -l

That *should* tell you how many levels deep you are (1 being the top 
level).  You could use this to modify your prompt at each login, or maybe 
make an alias that you could manually run before exiting.

That's the best I can come up with so far.
Hope that helps...

Joe
