Check date input

[Matsul]

Is there an easy way of checking if a date is in the format
YYYYMMDD ?

I have a script that takes a date as input and need it to exist with error in the case of an invalid date.

eg
>check_report 20070788

ERROR invalid date


thanks

Hi

>check_report 20070788

ERROR invalid date

Well, that "88" at the end of the string looks strange to me too.

If you have GNU [tt]date[/tt], that certainly can recognize that format. Maybe others too.

[blue]master #[/blue] date -d 20070788
date: invalid date `20070788'

[blue]master #[/blue] date -d 20070708
Sun Jul  8 00:00:00 EEDT 2007
