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


       base64 [OPTION]... [FILE]


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

       -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

       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.
