Hi 

How use iteration for the this filename abc_{yyyyMMdd}_xyz_{HHmmss}.

Here I need to generate filename using the above format. The the above format may be in following ways.

abc_{yyyyMMdd}_xyz_{HHmmss}

abc_{yyMMdd_HHmmss}

abc_{yyMMdd_HHmmsstt}

abc_{yyyyMMdd}_xyz_{HHmmss}

abc_{yyyyMMdd_HHmmss}_xyz

abc_{yyyyMMdd_HHmmsstt}

So I need to iterate using while or forloop to pick values lies between curly braces.
