## Problem (Bash / File System)
Implement a Bash function (or shell snippet) that returns the **maximum file size** (in bytes) under a given directory.
### Requirements
- Input: a directory path `DIR`
- Consider **regular files only** (ignore directories; you may ignore symlinks unless you explicitly choose to follow them)
- Search **recursively** under `DIR`
- Output: a single integer = the size (bytes) of the largest file found
- If there are no regular files, output `0`
### Example
If `DIR` contains files of sizes 10, 25, and 7 bytes (possibly in subdirectories), output `25`.
Overview: This question evaluates shell scripting and filesystem manipulation skills, specifically recursive file traversal and file metadata handling using Unix command-line tools, and belongs to the Coding & Algorithms domain (Bash/File System).
