Not 'single step' as such -- what you can do is run with '-x' which prints each line as it is executed. That's either: sh -x scriptname or you can add it to the #! line in the script, or just stick 'set -x' somewhere in the script body. If you use the 'set -x' form, you can set it up to trace through just the interesting parts of your code. (Somewhat counter intuitively 'set - -x' or 'set -o xtrace' turns on trace mode; 'set +x' or 'set +o xtrace' turns it off) This doesn't give you a way of arbitrarily querying the value of any variable, but you will be able to see all variable assignments as part of the trace. There's also a '-v' flag which adds displaying input read by the shell as it executes.
