Dear all,

I want to echo the previous date every time whrn i run a script

eg -

./test.sh

result-

Today is - 2006 06 29
Yesterday is - 2006 06 28

exactly like this.

How to do this ....?

Thanks,
Nayanajith.

If you're using GNU date (as on Linux systems,) you can do somthing like:
date -d yesterday
to get "now - 24 hours"

If you're not, you can use the wonderful datecalc script provided by Perderabo:

Code:

$ cat test.sh
#! /bin/ksh
a=`date +%y%m%d`
b=`TZ=CST+24 date +%y%m%d`
echo "Today is $a"
echo "Yesterday was $b"

NOTE: Command, `TZ=CST+24 date +%y%m%d` for yesterday's date I found at some thread, on the same board.

If you have GNU date avaialbe it has more powerful features.

Tayyab
