base64 [-d | -h | -v | -D] [-b count] [-i input_file] [-o output_file] DESCRIPTION

Default is 0, which generates an unbroken stream. -d --debug Print verbose log messages during processing. -D --decode Decode incoming Base64 stream into binary data. -h --help Print usage summary and exit. -i input_file --input=input_file Read input from input_file. Default is stdin; passing - also represents stdin. -o output_file --output=output_file Write output to output_file. Default is stdout; passing - also represents stdout. -v --version Print build version and exit. SEE ALSO
