base64 — base64 encode/decode data and print to standard output
base64 [OPTION...] [FILE]
Base64 encode or decode FILE, or standard input, to standard output.
Mandatory arguments to long options are mandatory for short options too.
−d, −−decodedecode data
−i, −−ignore−garbagewhen decoding, ignore non−alphabet characters
−w, −−wrap=COLSwrap encoded lines after COLS character (default 76). Use 0 to disable line wrapping
−−helpdisplay this help and exit
−−versionoutput 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.
