Create a text file with just the header. Use the cat command to join this file and the xyz file. $ cat HeaderFile.csv file1.csv > file1.csv You can repeat this on all files in a shell script.
Otherwise add the following line in the gdal2xyz.py script at line 144 [1]. dst_fh.write( 'Longitude,Latitude,Name' ) You will also have to create a separate vrt file for each csv file. The SrcDataSource element value changes for each file.
