The findutils package contains programs which will help you locate
files on your system.
The find utility searches through a hierarchy of directories looking for files which match a certain set of criteria (such as a filename pattern).
The xargs utility builds and executes command lines from standard input arguments (usually lists of file names generated by the find command). You should install findutils because it includes tools that are very useful for finding things on your system. This package contains the find, xargs, updatedb, and locate tools.
