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, it changes instead to the next directory from the top of the stack, [clarification needed] which can be used to toggle between two directories.

The Windows system directory (typically C:\WINDOWS\system32) is typically the first directory in the path, followed by many (but not all) of the directories for installed software packages. Many programs do not appear in the path as they are not designed to be executed from a command window, but rather from a graphical user interface. Some ...
In most computer file systems, every directory has an entry (usually named ".") which points to the directory itself.In most DOS and UNIX command shells, as well as in the Microsoft Windows command line interpreters cmd.exe and Windows PowerShell, the working directory can be changed by using the CD or CHDIR commands.
Shell functions, especially if the command being created needs to modify the internal runtime environment of the shell itself (such as environment variables), needs to change the shell's current working directory, or must be implemented in a way which guarantees they it appear in the command search path for anything but an interactive shell ...
Also, a major portion of the utility commands packaged with MS-DOS 1.0 came from IBM and their command line syntax used the slash character as a 'switch' prefix.
