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 de‐
coding, 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 --ig‐
nore-garbage to attempt to recover from any other non-alphabet bytes in the encoded stream.
ENCODING EXAMPLES
$ printf '\376\117\202' | basenc --base64
