Symlink
Symbolic link
A filesystem pointer that makes a path appear to be a file or folder elsewhere. Useful for shared configs; confusing when tools follow or refuse to follow links.
Concrete example
`ln -s ../configs/.env .env` creates a local `.env` that points at a shared file.
Why it matters
Shows up in monorepos, toolchains, and “file not found” mysteries.
