Bad Substitution

[Dinesh Tomar]

I have a key name suppose my.real.name and i want to display its value as
echo ${my.real.name}
it gives me an error Bad Substitution. Please tell me what to do?

Which shell are you using? Dot (.) is not allowed in variable name on bash (I guess ksh supports it).

I hope this helps.
