I would like to replace the last column values with another value using vim editor or sed command.I tried the below command but it replaces the data which is already present in my 2nd column sometimes.

```
:%s/,3/,2/

```

My sample data:

```
410339,166,1430,3
410340,112,1840,3
410341,109,1315,3
410342,123,1435,3
410343,230,3200,3
410344,857,36975,3
410345,125,4440,3
410346,105,1460,3
410348,122,1150,3
410349,314,2380,3
410350,132,4650,3
410351,136,7465,3
410352,103,1775,3
410353,101,1095,3
