Completion is generally requested by pressing the completion key (often the Tab ↹ key). Command name completion is the completion of the name of a command.
[24] [25] Other languages, such as Python, expose operating system specific API (functionality) through sys module, and in particular sys.argv for command-line arguments. In Unix-like operating systems, a single hyphen used in place of a file name is a special value specifying that a program should handle data coming from the standard input or ...
In the DOS era, it was customary to add a PATH {program directory}; %PATH% or SET PATH = {program directory}; %PATH% line to AUTOEXEC.BAT. When a command is entered in a command shell or a system call is made by a program to execute a program, the system first searches the current working directory and then searches the path, examining each ...
