Linux System Administration

1. Write a command to count how many files and directories contain the letter d in their names under /home/user/class/hw1 (do not need to consider items under the subdirectories). What was your command? What did you get
2. Create a symbolic link to the file /etc/shadow using the command ln -s /etc/shadow ~/foo. Does it work? If so, cat ~/foo to see the contents. What did you get? Why?
