I changed my code
As you can see i must use "Usage:" as my function so i changed my code to fullfill the assignment but it doesn't seem its working correctly. I'm new to unix to the whole using function is confusing. This is the new code im trying in my script:

Code:
#Vitaly Kuzyanov
usage()
{
 [ $# -eq 0 ]
 echo "usage: $0 argument"
}
if usage
     then echo "Enter 1 or more arguments"
     else "There were $# arguments on the command line"
     exit 1
fi
