docs/data/reusables/classroom/assignments-guide-protected-paths.md

If your assignment has files or directories that are used in the grading process or otherwise shouldn't be edited by students, you can designate them as protected file paths. If a student edits a protected file, a label will be applied to their submission on the assignment overview page for you to investigate. For more information, see "AUTOTITLE."

The patterns for protected paths follow rules similar to shell filename globs. It may contain the following meta-characters:

• *: Matches any file. For example, * matches all regular files, foo* matches all files beginning with foo, *foo matches all files ending with foo, and *foo* matches all files whose names contain foo (including at the beginning or end)
• **: Matches directories recursively or files expansively. For example, .github/**/* will match all files in .github and any of its subdirectories
• ?: Matches any one character
• [set]: Matches any one character in set(including sets like a-z)
• \: Escapes the next meta-character
