base32:tldr:d6a2d

The command "base32 --decode ${filename}" is used to decode a file from Base32 encoding.

Here is a breakdown of the command:

• "base32": This is the command-line utility that allows you to work with Base32 encoding.
• "--decode": This flag specifies that you want to decode the file.
• "${filename}": This is a placeholder that should be replaced with the actual filename (including the path if it is not in the current directory) of the file you want to decode.

When you run the command with the correct filename, the base32 utility will read the file, decode its contents from Base32, and output the resulting data to the console or store it in a new file, depending on how the utility is set up.
