recursive flag

The **recursive flag** is an option often used in programming and command-line tools to indicate that an operation should be applied not only to a specified item but also to all of its nested or contained items, such as files within directories or nodes within data structures. When enabled, the flag allows commands or functions to process elements recursively, traversing deeper levels automatically. This is especially useful in tasks like searching, copying, deleting, or modifying hierarchical data where manual iteration would be inefficient or impractical. Common examples include the `-r` or `–recursive` flag in Unix commands like `cp`, `rm`, and `grep`.
