Hi there,

I have a requirement to append dates going forward to a certain line in a file.
I'm not sure of how to go about this. Any help will be greatly appreciated.

Thanks

Please post your system, what shell you are using, what existing data looks like, and what you need the output to look like, and what you've tried so far.

Hi Gary,

My system is RHEL 5.5, bash shell

existing data:
2012/04/30,2012/05/01,2012/05/02,2012/05/03,2012/05/04,2012/05/08,2012/05/09,2012/05/10,2012/05/11,2012/05/14,2012/05/15,2012/05/16,2012/05/17,2012/05/18,2012/05/21

desired output:
additional 67 days appended to the end without Saturdays and Sundays and bank holidays.

I haven't tried anything as of yet as I'm not sure of what road to go down. But I have been looking at the date and cal functions to see if I need to use them.

Thanks
