Read-only, can be slowShow Nginx Include Lines
You need to see which files the main Nginx config is expected to include.
Command
grep -RInE '^[[:space:]]*include[[:space:]]' fixtures/nginx/nginx.conf fixtures/nginx/conf.d fixtures/nginx/sites-enabled
Before you run this
System impact: Read-only. Can create load on large logs, directories, filesystems, or process tables.
When not to use it: Do not assume every include glob matches files; inspect the target path when output looks suspicious.
Expected output
Include directives with config paths and line numbers.
System impact
Read-only, can be slow. Nothing changes. The command searches for include directives.
Scope this to the smallest useful path or service on busy systems.
Recovery / rollback: no state is changed.
When to use it
Use when an edited config file appears to be ignored.
When not to use it
Do not assume every include glob matches files; inspect the target path when output looks suspicious.
