Program Plan Intro
Path:
To represent the path of the file, first identify the type of the environment in the
- The path is a string or a sequence of characters separated by a forward or backward slash that contains the specified location of file.
- The path can be represented in two ways,
- Absolute path:
- It specifies the path of the file step by step, from the root of the directory.
- The path of the file starts from the root directory.
- Absolute path names can be represented with a forward slash (/) or backward slash (\) based upon the type of operating system.
- Relative path:
- It specifies the name from the current working directory.
- Relative path names can be represented with two dots (..) preceded by the forward (/) or backward slash (\)based upon the type of operating system.
- Absolute path:
The following diagram represents the directory tree structure on UNIX environment.
- Absolute path of the file in a UNIX environment is represented by separating the directories, subdirectories, and files by a forward slash (/).
