Need a sed command that uses variable

Hi ,

Seen some of wonderful posts. Please have look at my problem.

I have a text file ketkee.txt , which look like below.
GATES := apple mango banana
XMLCHECK := red blue green pink

My requiement is to find the line that has XMLCHECK in it. and append two variables followed by a space to all red blue green pink.

so that it look like

red_11 blue_11 green_11 pink_11

i tried the following script

DELIM="_"
RELCODE=11

tag=`grep XMLCHECK ketkee.txt | tr -s ' " " ' | sed 's/"XMLCHECK :="//g' | sed 's/[" "]/"$DELIM$RELCODE "/g'

But it is not working fine as it does not take value of the variables.if i replace variables with number like (sed 's/[" "]/_11 /g' ) it is working fine. But my i need to do this with the help of variables.

Please help me out with this.

Thanks
Ketkee

With sed (but I don't like it):
Code:
sed "/XMLCHECK/s/$/ /; /XMLCHECK/s/\([a-z]\) /\1${DELIM}${RELCODE} /g" ketkee.txt

With awk:
Code:
awk -v "d=$DELIM" -v "r=$RELCODE" '/XMLCHECK/ { for (i=3; i<=NF; i++) $i=$i d r } { print }' ketkee.txt

PS: this is not the correct forum to post a question like this! This is the Support Area Smilie
