I'm trying to get the PID's of a certain service. I'm trying to do that with the following command:

```
ps aux | grep 'DynamoDBLocal' | awk '{print $2}'

```

Gives output:

```
1021
1022
1161

```

This returns me 3 PID's, 2 of the service that I want, and 1 for the grep it just did. I would like to remove the last PID (the one from the grep) out of the list.

How can I achieve this?
