Base64 decode linux7/30/2023 ![]() Decode a file containing Base64 content and write the result to stdout: base64 -decode filename V2VsY29tZSB0byB0dXRvcmlhbHNwb2ludC5jb20KVGhpcyBpcyBhbiBhcnRpY2xlIGFib3V0IHRo Let’s run the base64 command with the file name as argument: $ base64 file1.txt This is an article about the base64 command. ![]() Here, we have a file named file1.txt: $ cat file1.txt Base64 encodes a file’s content provided as an argument and write the result to standard output: $ base64 filename Use 0 to disable line wrapping.Įxamples of base64 command: 1. Wrap encoded lines after the COLS character (default 76). When decoding, ignore non-alphabet characters provided as input. base64 command options -d, -decodeĭecode base64 data provided as input and print to standard output. Use -ignore-garbage to attempt to recover from any other non-alphabet bytes in the encoded stream. Mandatory arguments to long options are mandatory for short options too. When decoding, the input may contain newlines in addition to the bytes of the formal base64 alphabet. ![]() You can provide a file name as an argument, otherwise it will read standard input. Base64 is a collection of binary-to-text encoding techniques that can convert sequences of 8-bit bytes, which make up binary data, into sequences of 24 bits, which can be represented by four 6-bit Base64 digits. On Unix-like operating systems, the base64 command is used for the base64 encoding scheme the base64 command converts binary strings into text representations.
