Question 3

Please use thescript file “awkc8” discussed in the handout as a template to complete the following tasks:

Create an awk script file, “myawkmax4”, which will read 4 numbers, determine which number is the largest, and display it.

Your awk script, “myawkmax4”, mustinclude a self-defined function with 4 parameters. No awk built-in functions are allowed to be used in your script.

Please test your script at least with the following testing cases:$ ./myawkmax4 3 1 5 4The largest number is 5 $ ./myawkmax4 -3 -1 -2 -4The largest number is -1Question 4 Use the command “last –wi > myloginfile” to create a file “myloginfile” that shows all login information on the server since last time the log file was rolled over. Write an awk script, “myawkone”, to determine how many lines in “myloginfile” that contain the string “cfs264”. Test your script to make sure it works properly and then verify your result using either grep or wc command.
