locate
Definition
A command that searches for files by name. It is significantly faster than `find` because it queries a pre-built database instead of actively scanning the live hard drive.
Explain Like I'm New
Asking the librarian. Instead of walking through every aisle checking every book (which is what `find` does), `locate` just checks the library's pre-written index card catalog. It's instant.
Real World Example
You know you have a file called 'passwords.txt' somewhere on the computer. You type `locate passwords.txt`. It instantly prints the path.
