Create a 4-digit decimal counter by connecting four BCD counters together so that each digit increments at the correct time (D0 should increment at every clock edge, D1 should increment each time D0 reaches 9, D2 should increment each time D1 and D0 reach 9, and D3 should increment only when D0, D1 and D2 all reach 9). Then, build a 4-digit seven-segment controller system using a 4:1 4-bit bus mux, 2:4 decoder, and 2-bit counter. Connect the 4-digit decimal counter outputs to the seven-segment display controller, drive the counter from the 1KHz clock, and verify the counter counts through its range every 10s.

Write the command that can be used to answer the following questions. (hint: try each out on the system to check your results.) a. find all files on the system that have the word test" as part of their filename. b. search the path variable for the pathname to the awk command. c. find all files in the /usr directory and subdirectories that are larger than 50 kilobytes in size. d. find all files in the /usr directory and subdirectories that are less than 70 kilobytes in size. e. find all files in the / directory and subdirectories that are symbolic links. f. find all files in the /var directory and subdirectories that were accessed less than 60 minutes ago. g. find all files in the /var directory and subdirectories that were accessed less than six days ago. h. find all files in the /home directory and subdirectories that are empty. i. find all files in the /etc directory and subdirectories that are owned by the group bin."
