Unix command encode decode file

In contrast, decoding is the opposite of the coding process, which converts the encoded data back to its original format. Base64 encoding is mostly necessary to avoid transmission problems that occur when binary data is transmitted to text-based systems that cannot process the binary data correctly.

As a result, the information is lost or damaged in transit. In this article, we will explain how to use the base64 command to encode and decode the data in a string or file.

We ran the commands on the Ubuntu However, you can run the same commands on other Linux distributions as well. You can easily encode a string with the base64 command. This command encodes the text in the string using base64 and prints the encoded text to standard output as shown in the following screenshot. You can also decode the baseencoded text with the —decode or -d option. This command decodes the base64 encoded text and outputs the original text to standard output as shown in the following screenshot.

The base64 command can also be used to encode a text file. This command encodes the specified text file and prints its encoded form on standard output as shown in the following screenshot.

With the exception of the file extension, the names of all three files will be identical e. Identical in behavior to -3 , except that it will not create empty fork files.

So, if a file doesn't have a resource fork, hexbin will not create a. With this option selected, hexbin will only decode resource forks. Thus, if a file has a data fork, the program will ignore it.

With this option selected, hexbin will only decode data forks. Thus, if a file has a resource fork, the program will ignore it. With this option selected, hexbin will decode only the data fork of a file and will exchange all carriage return characters with line feeds.

This option should only be used with text files.
