coreutils-base32(1)

encode/decode data and print to standard output With no FILE, or when FILE is -, read standard input.

The data are encoded as described for the base32 alphabet in RFC 4648. When decoding, the input may contain newlines in addition to the bytes of the formal base32 alphabet. Use --ignore-garbage to attempt to recover from any other non-alphabet bytes in the encoded stream.

encode/decode data and print to standard output With no FILE, or when FILE is -, read standard input.

The data are encoded as described for the base32 alphabet in RFC 4648. When decoding, the input may contain newlines in addition to the bytes of the formal base32 alphabet. Use --ignore-garbage to attempt to recover from any other non-alphabet bytes in the encoded stream.

Print NAME with any leading directory components removed If specified, also remove a trailing SUFFIX

coreutils-basenc(1)

Encode/decode data and print to standard output With no FILE, or when FILE is -, read standard input.

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.
