base64:tldr:0ff63
The command "base64 --decode --input=${base64_file}" is used to decode a file that has been encoded using the base64 algorithm.
Here is the breakdown of the different parts of the command:
-
"base64": This is the name of the command-line utility to perform base64 encoding and decoding operations.
-
"--decode": This option tells the "base64" utility to perform the decoding operation.
-
"--input=${base64_file}": This option specifies the input file that needs to be decoded. The variable "${base64_file}" is used to represent the actual filename or path of the base64 encoded file. You need to replace "${base64_file}" with the appropriate file path before running the command.
By executing this command, the base64 encoded file will be decoded, and the output will be the original file or data before it was encoded using base64.
