Which package provides the locate command on most systems?

• A. mlocate
• B. locate
• C. plocate
• D. findutils

Answer: (A)

Searching with locate relies on a prebuilt index of the filesystem. The locate command is provided by the mlocate package on most systems, which includes both the locate binary and the updatedb utility that builds the index. That combination is what makes locate fast and useful for quickly finding files by name.

Other options exist in different forms, like plocate (a newer, faster drop-in replacement) or a version sometimes associated with locateutils, but on most distributions the standard, widely used provider you’ll encounter is mlocate. The findutils package, while it includes many file-related tools like find and xargs, does not supply the locate command, so it isn’t the correct source here.
