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.
