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.

Thank you!

shell scripting

Asked by alphaomega232 in Linux

How would I write a script for  the scriptfile "puzzlescript"  to make the gotchascript echo back "gotcha" ?  The idea here is to set up the first script named gotcha so that when $sum and $rightsum are equal the script will echo back gotcha.  It is set up to look at and execute the scriptfile 'puzzlescript'  to see if its value is equal to $rightsum.  Puzzlescript is set up in another part of the directory and has to be written in such a way that when the gotchascript comes to run it, it triggers the echo gotcha from the gotchascript.

#!/bin/bash
#gotchascript

if [ ~/puzzle ]
then
sum=` ~/puzzle 5 10 20 $$`
rightsum=`expr 35 + $$`
if [ $sum -eq $rightsum ]
then
echo gotcha
echo
fi

What I've come up with so far is,

#!/bin/bash
#puzzlescript

sum=`expr 5 + 10 + 20 + $$`
echo $sum

but it won't cause the echo gotcha from the gotchascript
