Hi
what i did is.
requpd=",0019,0314,None"
ADDR=ws_
REQUPD=`echo $requpd | sed "s/,/ /g"`
for upd in $REQUPD; do
ckupd=`echo $upd | cut -sd: -f1`
if [ -z "$ckupd" ]; then
ckupd=$upd;
reqplats="";
else
reqplats=`echo $upd | cut -d: -f2`
fi
if [[ -n "$reqplats" && "$reqplats" = None ]]; then
continue;
fi
FINAL="$FINAL ${ADDR}$ckupd"
done
echo $FINAL;
Above can be one way of doing this.
but there are many.
Thanks you all for your responses.
Thanks
Sumit
