The command interdiff -w ${old_file} ${new_file} is used to generate an "interdiff" between two patches or diff files.

The term "interdiff" refers to the difference between two different versions of a patch, specifically showing the changes made between the two patches rather than the changes made in each individual patch. It helps identify the specific changes made when multiple patches are applied sequentially.

Here's a breakdown of the command and its components:

• interdiff is the name of the command or program being executed.
• -w is an optional flag that can be included to ignore whitespace differences when comparing the files. It helps in cases where differences in white spaces (such as indentation or line spacing) are irrelevant to the changes made.
• ${old_file} is a placeholder for the name or path of the original/older patch file that serves as a reference point.
• ${new_file} is a placeholder for the name or path of the newer/modified patch file that is being compared to the original.

To use this command, you would replace ${old_file} and ${new_file} with the actual names or paths of the respective patch files you want to compare. The command would then generate an interdiff output, highlighting the changes made between the two patches.
