Thanks guys for your suggestions;

FILE1=/home/pavi/DS.txt
FILE2=/home/pavi/chain.txt

awk -F ":" '{print $1}' $FILE1 > f1.txt
awk -F " " '{print $2}' $FILE2 > f2.txt


DS.txt contains;

ALBD:xxxxx
FLN:yyyyyyy
WLG:ttttttt

chain.txt contain;

ECK: ECK: 331
ECK: ECK: 336
FED :FED :427

the result.txt has to look like this;

WLG :WLG :243
WLG: WLG: 244
WLG :WLG: 245
WLG :WLG :246
MAT: WLG :247

the script has to match the 1st column from DS.txt with the 2nd column
of chain.txt and only those that matched, move all the corresponding
1st , 2nd and 3rd columns of chain.txt to a output file say result.txt

this is what i am trying to accomplish.
