xdelta:tldr:7d542

The command you provided is using the "xdelta" application with certain options and arguments. Here's a breakdown of the command:

• "xdelta": It is the name of the application or command being executed.
• "-d": This option specifies that the command is in "delta" mode, targeting decompression or patching.
• "-s": This option indicates that the following argument is the source file being used as a base.
• "${path-to-input_file}": It should be replaced with the actual path to the input file that is the base for the delta operation.
• "${path-to-delta_file-xdelta}": It represents the path where the delta file created by the xdelta command will be saved. This delta file contains the changes or differences between the base file and the desired output file.
• "${path-to-output_file}": It should be replaced by the path where the final output or result file will be saved.

In summary, this command is using xdelta to apply the changes specified in the delta_file to the input_file (base file) and produce the output_file. It essentially performs a delta-based update or patching operation.
