Need help for writing shell script
I need some help in writing a shell script, it basically need to delete all my older files , the file name structure is like that :
· song – constant prefix.
· 100000732 – 9 digits unique key [per msisdn]
· 200506114528 – time stamp [DDMMYYHHMISS format]
The unique key is the same for each play list of specific msisdn.
The only thing that changes is the timestamp.
so i need for each unique key (there are more then one) the news file will remain
Can anyone help me?
