Need help with Linux!!

5.4) Based on Lab 7, Handouts 7 (example 1), and HW 7, please create a file called myloginfile as shown below and then write an awk script called mylogincheck to check on file myloginfile to see who spent less than one (1) hour on the system and then display those login records. (The last column of the output shown below indicates the time spent on the system).

$ last wi | grep "Mar 31 | head -5 > myloginfile

$ cat myloginfile

a) Please provide your script below (hint: Example 1 in AWK Handouts for week 7 can be used as a template)

b) Please provide the screenshot below:

5.5) Please use the solution to HW 7, hands-on problem 2, as a template to write a shell/awk script, called mymiddle3, that reads in three (3) numbers and then uses a self-defined function to determine the middle number in value. The middle number should be displayed in the main script, not inside the function you define. Please use the following testing cases to test your script:

$ ./mymiddle3 5 3 8

The middle number is 5.

$

$./mymiddle3 -2 -9 -7

The average is -7.

$

$ ./mymiddle3 8 3 8

The middle number is 8.

$

$ ./mymiddle3 0 -1 -1

The middle number is -1.
