BASE64(1)                        User Commands                       BASE64(1)



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.
