When called, they use a directory stack to sequentially save and retrieve directories visited by the user. [ 1][ 2] They are widely available as builtin commands in many command-line ...
In MS-DOS, a batch file can be started from the command-line interface by typing its name, followed by any required parameters and pressing the ↵ Enter key. When DOS loads, the file AUTOEXEC.BAT, when present, is automatically executed, so any commands that need to be run to set up the DOS environment may be placed in this file.
