I am trying to use a function in my script. I'm not quite sure how to complete it. This is my assignment:
The first version of hw12.sh should display the usage message "usage: $0 argument", "Enter one or more arguments." when no arguments are on the command line.
$ hw12.sh
usage: hw12.sh argument
Enter one or more arguments.
- The second version of hw12.sh should display the message "There were $# arguments on the command line" if there were 1 or more arguments on the command line. Here is an example.
$ hw12.sh abc 123
There were 2 arguments on the command line.
- The final version of hw12.sh has the following change. Display the usage message from a function. Here is an example.
$ hw12.sh hello hw12.sh
There were 2 arguments on the command line.
$ hw12.sh
usage: hw12.sh argument
Enter one or more arguments.
This is my code that wrote but it says i have a syntax error any help would be appreciated. Thank you
