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!

Deleting Files with Bash Script

Asked by techsupportcpm in Bourne-Again Shell (bash), Linux Administration

Tags:

Hello,

One of my CMS applications makes backups of my INTRANET site at 2 times, 7am and 8pm on a daily basis. As you can see from the files below is that there are web backups and intranet backups on possibly the same day, and sometimes different days in the same /usr/local/bin/cms/backup directory. What I am trying to do is delete the oldest files of both sets to leave the 2 newest. I cant write a bash script to delete anything older then a certain day, but doing this might fall into a problem area where the Web backup does not have a newer copy like the Intranet does and would delete the pervious backup. Any suggestions on some code to make into a cron job that will delete all previous files except the 2 most recent of 2 different file types? This is an issue because every Intranet backup is 5GB and every Web backup is 2GB so if i have large amount of files in there at this size my server gets quite low on space.  Any advice would be greatly appreciated.

(As seen here I want to get rid of the oldest Web backup of 2/12, and the Intranet backup of 4/12, these dates vary as I have not figured out the reason the backups are so sporadic)
