Relative Pathnames

Relative pathname indicates the location of a directory, relative to the current working directory. Any pathname that does not begin with the root directory represented by ( / ) or a tilde ( ~ ) is a relative pathname. A relative pathname  traces a path from the working directory to a file. The pathname is relative to the working directory.
Like absolute pathnames, relative pathnames can be trace a path through many directories. The simplest relative pathname is a simple filename, which identifies a file in the working directory.
