NAME

       base64 - base64 encode/decode data and print to standard output

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
	      Output version information and exit.

       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
       bytes of the formal base64 alphabet.  Use --ignore-garbage to attempt to recover from any other non-alphabet bytes in the encoded stream.
