How to I read the second line of the output of a command into a bash variable?

Question

I have a command that prints several lines and I do want to put the second line into a bash variable. like `echo "AAA
BBB"` and I want a bash command that would put `BBB` in a bash variable.

Accepted Answer

With `sed`:

```
var=$(echo -e "AAA
BBB" | sed -n '2p')
```

With `awk`:

```
var=$(echo -e "AAA
BBB" | awk 'NR==2')
```

Then simply, echo your variable:

```
echo "$var"
```
