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.

       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 wrap‐
              ping

       --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.
