How to get yesterdays julian date

Hi,

Was using date +%Y%j to get current julian date. Can anyone let me know how can I get y'day's julin date. Thx

Did check FAQ but couldn't find anything.

Thanks.

that wont always work....

Code:
date '+%Y%j' --date='1 day ago'

Unless your NOT using a GNU date.

But that is not really a true Julian date that year and day of year. 2009021

The Julian date for CE 2009 January 21 00:00:00.0 UT is
JD 2454852.50000

Change your TZ and then do the date command. Like so:

TZ=GMT+24
echo `date`
