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:

script: phonedecode

This script should take a phone number from the command line and translate it into just numbers. For example, if it is invoked as phonedecode 1-800-eat-meat, it should print 1-800-328-6328. The translation shoult follow what is found on a touch-tone phone.

  1. The attempts at a solution (include all code and scripts):

This takes a file as an argument: phonedecode testphonedecode.txt
(where testphonedecode.txt contains: 1-800-eat-meat) and phonedecode contains:

(sed 's/[a-c]/2/g' | sed 's/[d-f]/3/g' | sed 's/[g-i]/4/g' |
 sed 's/[j-l]/5/g' | sed 's/[m-o]/6/g' | sed 's/[p-s]/7/g' |
 sed 's/[t-v]/8/g' | sed 's/[w-z]/9/g') < $1

But I would like to be able to write: phonedecode 1-800-eat-meat
how can I go about passing the telephone number as the argument?

  1. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):
