The a.txt was the one destined to be generated, but the generation time 
won't be know, which might last from 2 mins to 2 hours,

so I wish there is a script there check whether it's generate or not, if 
generate, so it can proceed further.

It's a bit dynamic process, sort of .. haha ...

Thanks for your advice,

Best regards,
