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.
