BASENC(1) User Commands BASENC(1) NAME basenc - Encode/decode data and print to standard output SYNOPSIS basenc [OPTION]... [FILE] DESCRIPTION basenc encode or decode FILE, or standard input, to standard output. With no FILE, or when FILE is -, read standard input. Mandatory arguments to long options are mandatory for short options too. --base64 same as 'base64' program (RFC4648 section 4) --base64url file- and url-safe base64 (RFC4648 section 5) --base32 same as 'base32' program (RFC4648 section 6) --base32hex extended hex alphabet base32 (RFC4648 section 7) --base16 hex encoding (RFC4648 section 8) --base2msbf bit string with most significant bit (msb) first --base2lsbf bit string with least significant bit (lsb) first -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 --z85 ascii85-like encoding (ZeroMQ spec:32/Z85); when encoding, input length must be a multiple of 4; when decoding, input length must be a multiple of 5 --help display this help and exit --version output version information and exit When decoding, the input may contain newlines in addition to the bytes of the formal alphabet. Use --ignore-garbage to attempt to recover from any other non-alphabet bytes in the encoded stream.
