echo $SHELL
I get this:

/bin/sh
99.4% chance it will be Bash :)

Command: ps -p $$
I get this:

ps: invalid option -- p
BusyBox v1.13.2 (2010-09-05 19:40:10 CEST) multi-call binary

Usage: ps

Options:

Ok, this did me some more info but I'm afraid I'm still none the wiser as to what version shell this machine has. I'm trying to do a little shellscript and I'm finding some certain things do not work so I thought I would try and find what version of shell I'm using to start with...
