Data how to update a .csv file?

Hi everyone,

echo "Fatal alerts:", $(cat a.txt) > test.csv

now what i want to do is update the same .csv file (test.csv) by adding a new record in the next row. is this possible in unix? if so please help me!

_______________________
1|Fatal alerts: | no rows selected
