1. How do you find out the number of directories up to two levels in our home directory tree?

2.) Create several files containing some arbitrary words. Then create a file named foo that contains the names of such files, one file name per line. Devise commands to count the total number of words in all these files and store the result in a variable total. (4 points. If you can devise one single command to do everything, you will receive 2 bonus points.) Note: when deriving your command(s), you cant assume that you know the names of the files that you created in the first place.

Can someone please answer the following questions above. Both should be done using Unix Commands. Please provide screenshot as well. I will upvote if the answers are correct. Thank you in advance!
