Use the attached script, caljd.sh.

DT=$(caljd.sh -y -s $(caljd.sh -p 2))
echo "Two days ago in YYYYMMDD format was ${DT}"

Invoke as caljd.sh -u for full usage and many examples.

#]perl -le 'print scalar localtime time - 86400'

Hi,

Download caljd.sh script in ACS reply. IT is really useful. And try as said by ACS. Or get usage as,
