Hi, If you are on a linux system, you can use these linux commands through pipe. Otherwise : - perl would do a great job on this. - if you are familiar enough with SQL syntax, you can use the development version of the sqldf package to work on csv files as if they were database tables. See example 8 in http://code.google.com/p/sqldf/
