Looking for a Windows Batch program to remove blank rows from a csv file

This worked. Thank You! So the /v is to skip when the string is found and the "^,*$"  identifies the string of commas?

You are correct: /V is to output only lines that do not match the search string and "^,*$" is a regular expression which defines a string of commas.  ^ means match at the beginning of the line ,* means match 1 or more commas and $ means match at the end of the line.

Thank You for your help!
