In some systems, a filename reference that does not include the complete directory path defaults to the current working directory. This is a relative reference. This is a relative reference. One advantage of using a relative reference in program configuration files or scripts is that different instances of the script or program can use ...
At that moment, the relative path for the desired directory can be represented as: ./bobapples or for short: bobapples and the absolute path for the directory as: /users/mark/bobapples Given bobapples as the relative path for the directory wanted, the following may be typed at the command prompt to change the current working directory to bobapples:
It is sometimes called the current working directory (CWD), e.g. the BSD getcwd [1] function, or just current directory. [2] When a process refers to a file using a path that does not begin with a / (forward slash), the path is interpreted as relative to the process's working directory.

The pushd ('push directory') command saves the current working directory to the stack then changes the working directory to the new path input by the user. If pushd is not provided with a path argument , in Unix it instead swaps the top two directories on the stack, which can be used to toggle between two directories.
For instance, bash builtin commands pwd and cd operate on the current logical directory. pwd is often used in scripts to determine the actual current working directory. When any path is used with a system call, any use of .. will use the actual filesystem parent of the directory containing the .. pseudo-directory entry.
It also offers a SUBST command which allows the assignment of a drive letter to a directory. One or both of these commands were removed in later systems like OS/2 or Windows NT , but starting with Windows 2000 , both are again supported: The SUBST command exists as before, while JOIN's functionality is subsumed in LINKD (part of the Windows ...
