$ sudo apt-get install locate manpages manpages-posix

$ mkdir -p ~/emptydir/makesure

If a file is not found using the locate command, the database might be simply out of date and needs to be re-ran. It is possible that updatedb is also not indexing partitions such as those contained on removable media (USB sticks), and the file may be present there instead of the regular system partitions.
In preparation for this recipe, be aware that two concepts were inadvertently introduced: git and manpages. Manpages are among one of the oldest forms of help documentation available in Linux, and git is a version control system that simplifies management, versioning, and distribution of files such as code. Knowing how to use either is certainly beneficial, but beyond the scope of this book. For more information about git, check out another Packt book: GIT Version Control Cookbook.
