UNIX for Dummies Questions & Answers

I am curious if the following can be done in a file in unix. Let's say I have a flat file with the following data

AAA,12,2,,,,
BBB,3,1,,,,
CCC,,,,,
DDD,2,,,,,
SQQ,,,,,
ASJ,,3,5

I only want to capture the data with values into a new file. If the data contains the pattern ,,,,, as in records CCC and SQQ above, I want it filtered out, however I want to keep all of the other records.

The resulting file should look like:

AAA,12,2,,,,
BBB,3,1,,,,
DDD,2,,,,,
ASJ,,3,5

Any ideas on how to accomplish this?

??

ant:/tmp $ cat aaa
ersadf,3,4,,,
sjdhfkjhs,,,,,
sdajf,2,,6,,,
lkjdf,,,,
totot,,3,,,
fkdjgh,,,,,
ojdofjs,2,,,5,
ant:/tmp $ cat aaa|grep -v ",,,,"
ersadf,3,4,,,
sdajf,2,,6,,,
totot,,3,,,
ojdofjs,2,,,5,
ant:/tmp $

Thanks! - That worked perfect!!
