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!

Rearranging columnar data into a table with ksh

Asked by mikestan in Unix Systems Programming

Tags: ksh, rearrange, table, columnar, data

I have a data file that is in the following format:

   TIME       : 00:00:00 00:06:00
   TOTAL       : 9947
   RTT     : 0.78 seconds
   ... <other data follows that is not important> ...
   TIME       : 00:06:00 00:12:00
   TOTAL       : 9123
   RTT     : 0.54 seconds
   ... <other data follows that is not important> ...
   TIME       : 00:12:00 00:18:00
   TOTAL       : 8547
   RTT     : 0.48 seconds
   ... <other data follows that is not important> ...
   etc...

and want to re-arrange the data using a ksh script (or should I use perl) to read (space delimited text):
00:06:00 9947 0.54
00:12:00 9123 0.78
00:18:00 8547 0.48
... etc.

so I can report against it using rrdtool (date is in the file name and will be joined w/ time stamp to form epoch seconds). Before I do so, how should this data be rearranged? I have a grep statement to get only the rows shown above, something like: grep "TIME\|TOTAL\|RTT" DATAFILE_09282006.out.
