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