The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

how to use shift for array within while loop

Asked by sugarfreeless in Linux Programming, Unix Systems Programming

Tags: , ,

Experts,

I have a while loop that does some work on a number of cmd line parameters in sucession.

creates an array within the while loop.
based on the array created I want to exclude the first element within that array but only if it matches.
problem is when I use shift it effects the cmd line parameters instead and not the array.

EG
script.bash one two three four
while [ "$#" -gt 0 ]
do
array='sql code'
test=$(echo ${array} | awk '{print $1}')
if [ ${test} = badElement ];then
shift
fi
done

so when running this code and executing my test
the shift changes the command line argument from one to two
what I want is the shift to remove the first element inside the array instead
