Re: [foxboro] Date comparison in Unix scripts

Specifically, I am trying to manage some system PM items.  I would like to
be able to check a list (flat file) of tasks and determine if the task is
overdue.  I would also like to determine when the task is more than X days
overdue to flag it as a high priority.  The second part requires the ability
to compare the stored date with the current date to see how many days in the
past it is.

Thanks,
Terry

No.  Dates are always yucky, on any os.  A moment's thought about things
like daylight savings and leap years will start to reveal some of the
horrible complexities, and why there just isn't an easy way.

What are you trying to do?  There may be an easier way to do this using
"make".  If you have perl, there's a glimmer of hope too.

Cheers

Jason
