This script writes out individual contacts from a single vCard file (.vcf) into separate files.
The major difference and advantage to approaches based on cut or csplit is that files are named with the full name as file name.
Currently non-alfanumeric characters are replaced by _.
Usage
perl split_vcard -i input_file -o output_dir [OPTION]
On Unix platforms
./split_vcard -i input_file -o output_dir [OPTION]
Currently, the only supported option is -v (execute split_vcf.pl without parameters for more informations)
The source code come from https://code.google.com/archive/p/split-vcf-file/, it has been adapted minimally to work on non-windows platforms.
