Thanks Koneark,

but i have one more prob here.
when i run
echo "today--RSS_URL=http://someurl" | sed 's/\(.*\)--\(.*\)=\(.*\)/x1=\1\nx2=\2\nx3=\3/'

it is giving the out as below.

x1=todaynx2=RSS_URLnx3=http://someurl

But I need the out put as

x1=today
x2=RSS_URL
x3=http://someurl

and i need to export these x1, x2 and x3 to the shell.

Thanks,
Eswar

Code:

#!/bin/sh

var='today--RSS_URL=http://someurl'

x1=`echo $var | sed "s_\(.*\)--\(.*\)=\(.*\)_\1_"`
x2=`echo $var | sed "s_\(.*\)--\(.*\)=\(.*\)_\2_"`
x3=`echo $var | sed "s_\(.*\)--\(.*\)=\(.*\)_\3_"`

echo "Testing results: var($var) x1($x1) x2($x2) x3($x3)"

This script will set the variables as you wish. You can export them or modify them or do whatever you want with them then.
