Step 1.
After logging in type ls
You will see a file data.txt

Step 2.
In that data.txt file we need to find the word millionth and our password will be next to it. 
Go ahead and try a cat data.txt to see what happens.We get a giant stream of data, we need to filter that data.We know from the last level that grep is great for searching for a matched string. Lets pipe our cat of data.txt to grep and match the word millionth.

Type cat data.txt | grep millionth and our password for level 8 is displayed.
