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!

Unix Shell script perl ( sed awk grep ) to screen out duplicate keys

Asked by sunhux in Shell Scripting, Perl Programming Language, Unix Operating Systems

Tags: Unix Shell script perl ( sed awk grep )

I have the following file sorted by the first column as the sort key :

111 found in platter 3297
111 found in platter 3322
1122 found in platter 3232
1129 found in platter 3297
1133 found in platter 3238
1133 found in platter 3297
1133 found in platter 3211
1255 found in platter 3213
1258 found in platter 3289
.....


I need a script that reads the above file & produces only those
lines / records that have the sort key occurring more than once,
so based on the above sample, the output should be :

111 found in platter 3297
111 found in platter 3322
1133 found in platter 3238
1133 found in platter 3297
1133 found in platter 3211
