Uw.shell by example, 3rd Edition chapter 7th answers to awk programming chapter

Run the command awk-F scriptname filename.

For example, if the first script name is bigawk. SC1, the file name is datafile # The content of datafile is the same as the previous content, so I will not post it here. You can check out the content in my previous section.
The actual command: awk-F bigawk. SC1 datafile

The last parameter is passed through the command line.

The actual command is: awk-F myfunc. SC 3 datafile

Here, you can use numbers 1, 2, and 3 to specify the average value of the contribution of everyone in the current month.
