Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!
1. The problem statement, all variables and given/known data:
Create a script that displays output with a specific parameter.
For example, for a script called score
Typing score steelers would show
19 - 12
score greenbay
20 - 10
and so on.
The big question here is how to create a script that will run when using a parameter.
2. Relevant commands, code, scripts, algorithms: 3. The attempts at a solution (include all code and scripts): 4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):
Arizona State University, Temoe, USA, Mazzola
Note: Without school/professor/course information, you will be banned if you post here! You must complete the entire template (not just parts of it).

Then extra clue for the test you displayed: How do you show the content of a variable?...

Hi,
I'm new to the Ash shell so my apologies if this is well known. In normal maths and other shells and languages I've used, the modulo operator always returns a positive remainder. For example see this discussion (first post so I can't hyperlink it):

Ok, i've been messing around in debian the past few days, setting up programs like subversion, mysql and logrotate. The purpose of this script is to use subversion to backup the binary logs.
