A slightly more complicated perl script would be my first choice if
coding is the solution, but grep already has a feature that could be
used to provide a solution as shown by the following scriptlet
(including an scaled data file) :

$ cat > c.csv
USER,TIP
john,0
jane,10
carenas,100
$ ( grep -m1 USER && grep carenas ) < c.csv
USER,TIP
carenas,100
