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


       base64 [OPTION]... [FILE]


       Base64 encode or decode FILE, or standard input, to standard output.

       With no FILE, or when FILE is -, read standard input.

       Mandatory arguments to long options are mandatory for short options too.

       -d, --decode
              decode data

       -i, --ignore-garbage
              when decoding, ignore non-alphabet characters

       -w, --wrap=COLS
              wrap encoded lines after COLS character (default 76).  Use 0 to
              disable line wrapping

       --help display this help and exit

              output version information and exit

       The data are encoded as described for the base64 alphabet in RFC 4648.
       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.
