I'm running the following command:

```
cat /tmp/myfile.log | sed -n -e 's/^.*Expire: //p'

```

Which returns the following string

```
04-nov-2018

```

I then want to run that string through the following command:

```
date -d '04-nov-2018' + "%s"

```

that will return the unixtime:

```
1541304000

```

How do I run that in a single command line?
