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!

Bash script to parse line by line

Asked by jameswalt in Linux Programming

Tags: , , , ,

I have a file with the following format:
d    28854           cpmnt    open     username  owner  3   062 description of problem
d    28855           cpmnt    open     username  owner  3   062 description of problem
d    28859_d           cpmnt    open     username  owner  3   062 description of problem


I need to "grab" the second token of every line, no matter how large the token is. The 2nd token is characterized by whitespace delimerters on both sides. (generally spaces, but I would like to be able to handle tabs as well).
I would like generate a new file and insert onto each line the 2nd token from this first file.
This is a fun programming excercise. I have been working on it for a little while now, but just do not know the commands wlel enough to be able to get it where i need it to be.

The faster the response on this, the more points I will add to the question, and the better grade I will offer. Please help!

Here is the relevant portion of the script that I have so far (not a big deal at all)
It simply reads in the file line by line and outputs it to the terminal

# START OF SCRIPT
exec < currentDefectsLog
while read line
