📦 3.6 'base64': Transform data into printable data

base64 transforms data read from a file, or standard input, into (or from) base64 encoded form. The base64 encoded form uses printable ASCII characters to represent binary data. Synopses:

base64 [OPTION]... [FILE]
base64 --decode [OPTION]... [FILE]

The base64 encoding expands data to roughly 133% of the original. The base32 encoding expands data to roughly 160% of the original. The format conforms to RFC 4648 (https://tools.ietf.org/search/rfc4648).

🚀 Quick Reference

Use Case	Command	Description
📄 Encode a file	base64 FILE	Encode FILE to base64, output to stdout
🔓 Decode a file	base64 --decode FILE	Decode base64-encoded FILE to original data
📏 Encode with custom wrap width	base64 -w 0 FILE	Encode without line wrapping (single line)
🗑️ Decode ignoring garbage	base64 --decode --ignore-garbage FILE	Decode, ignoring unrecognized bytes

📋 Synopsis

base64 [OPTION]... [FILE]
base64 --decode [OPTION]... [FILE]

📖 Description

The program accepts the following options. Also see Common options.

⚙️ Options

• -w COLS / --wrap=COLS — During encoding, wrap lines after COLS characters. This must be a positive number. The default is to wrap after 76 characters. Use the value 0 to disable line wrapping altogether.
• -d / --decode — Change the mode of operation, from the default of encoding data, to decoding data. Input is expected to be base64 encoded data, and the output will be the original data.
• -i / --ignore-garbage — When decoding, newlines are always accepted. During decoding, ignore unrecognized bytes, to permit distorted data to be decoded.

An exit status of zero indicates success, and a nonzero value indicates failure.
