Shell Programming and Scripting

Hi
I have a 'sed' editor command trying to update a line in the file:

NEW_PX=7777

echo 'PX_LIST="2259 221 270 263 2874" ' | sed "s/PX_LIST="/&${NEW_PX} /"

The above command should add value of NEW_PX as the first entry inside the quotes, so the output should look like this:

PX_LIST="7777 2259 2215 270 263 2874"

The command works fine if the value 777 is hardcoded:
echo 'PX_LIST="2259 221 270 263 2874" ' | sed 's/PX_LIST="/&7777 /'

Thanks for any help and advice -A

Code:

#!/bin/ksh

NEW_PX=7777

echo 'PX_LIST="2259 221 270 263 2874" ' | sed "s/PX_LIST=\"/&${NEW_PX} /"

THANKS A LOT vgersh99 !!!! You saved me from parsing this string....... All The best! -A
