Try this:
exec 9>&2 # reserve file descriptor for tracing
trace() {
local cmd=$(printf '%q ' "$@")
printf '+ %s\n' "$cmd" 2>&9
"$@"
}
trace some command
This will only work for simple commands, not for grammatical constructs
nor for anything with a function-local scope.
(The above code should also work on bash and ksh93.)
