Check in script to make sure it only starts after Midnight.

[Brad Sheldon]

Hi   there,   we have a script which we need to run after midnight. 

I need  a check in the script to make sure it is starting up  at midnight or a minute after as it invloves DB reorgs which must only be run after 12:00am.

I have done some testing but have only come up with some perl snippets.

the below code checks for the previuos day but i need it in korn

perl -MPOSIX=strftime -le 'print strftime "%m/%d/%Y",localtime(time-86400)'

Cheers Brad.

ACS's date hammer does that sort of operation in shell script:

Usage is included and pretty straightforward

Alternatively get GNU date from the GNU coreutils (and run-time dependencies) here:

http://hpux.connect.org.uk/hppd/hpux/Gnu/coreutils-8.14/

with GNU date you can do plenty of simple date arithmetic like

date --d "-1 days"

Any reason you don't just schedule the script with crontab and don't put the check in the script?
