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!

Remove and rename with wildcards

Asked by markgeer in Linux Programming

Tags: , ,

I have years of experience writing DOS and Windows batch files, but I'm new to Linux, and am having trouble getting some bash shell commands to work with wildcards.  Here is the pseudo code for a two-step shell script that I need:
1. Look for files like: "abcdef*.bak" in a particular directory and delete them
2. Look for files like: "abcdef*.dmp" in this directory and rename them to *.bak

In DOS / Windows I would use this:
if exist C:\temp\abcdef*.bak del C:\temp\abcdef*.bak
if exist C:\temp\abcdef*.dmp ren C:\temp\abcdef*.dmp *.bak

In Linux (I have RedHat ES4) I found that this works to find a particular file, but not with wildcards (although the "rm" command is happy to work the wildcard):
if [ -f /tmp/abcdef01.bak ]; then
  rm /tmp/abcdef*.bak
fi

I may be safe with that at least 99% of the time, since the directory will usually have a file like "...01.bak" if there are any others with higher numbers, but to be completely safe I would like to use the wildcard.  This must be possible in a shell script, right?Start Free Trial
