unix assignment 3

/in /by

Need assistance in completing a Unix  Scripting assignment. The assignment asks to write 2 scripts

 

Errors:

 

The value assignment to numfiles in fn_average and the directory processing in fn_filter both require filename expansion.  If you review 18.2 Globbing, in the Advanced Bash-Scripting Guide, you will get an idea how to do this.
Also, please re-read the assignment instructions for the requested output format of this script.
