SYNOPSIS
base64 [OPTION]... [FILE]
DESCRIPTION
Base64 encode or decode FILE, or standard input, to standard output.
-w, --wrap=COLS
Wrap encoded lines after COLS character (default 76). Use 0 to disable line wrapping.
-d, --decode
Decode data.
-i, --ignore-garbage
When decoding, ignore non-alphabet characters.
--help Display this help and exit.
--version

With no FILE, or when FILE is -, read standard input.
The data are encoded as described for the base64 alphabet in RFC 3548. When decoding, the input may contain newlines in addition to the
