Absolute Pathnames

An absolute pathname begins with a slash (/). The Absolute path defines the location of a Directory or a file from the root file system (/). The absolute path contains the full path to the directory or file.

Examples of Absolute Path

/usr/share/doc                    (Absolute path for a Directory)
/usr/share/doc/bash/README        (Absolute path for a Directory)

Question: List the directory which contains all docs by using Absolute path.
Answer:

Relative Pathnames

The relative pathname does not begin with /. It specifies the location relative to your current working directory. Below are some examples of relative pathnames, relative to particular directories.

Current Directory Relative Pathname
/usr/shar/doc/HTML/ index.html
/ usr/share/doc/HTML/index.html
/usr share/doc/HTML/index.html
