search for: notificationid

I am trying to use sed to change a value in a pipe. ------------------- This is the two line script CHANGE="1234" cat my_file.txt | sed 's/CANCELID/$CHANGE/' > cancel.txt ------------------- and the my_file.txt has: <v1:notificationId>CANCELID</v1:notificationId> it gets changed to $CHANGE instead of the actual value 1234 . I tried putting a \ in front of the $ also and made no difference. What am I not doing correctly. Thanks, jerry
