[kə′mand ‚līn]command line
A text-based user interface to the computer. The command line is a blank line and cursor on the screen, allowing the user to type in instructions for immediate execution. All major operating systems (Windows, Mac, Unix, Linux, etc.) support command lines that programmers and power users can employ to perform file management operations directly and often more efficiently than by using a graphical user interface (GUI). After typing a command, it is executed by pressing the Enter key.Windows Examples
There are numerous Windows commands in this encyclopedia, and two examples follow. To do these operations in Windows Explorer or a Windows-based Pkzip utility would take numerous mouse clicks. See Windows commands.
Command Operation Performedcopy *.html d:\\abc Copy HTML files to ABC folder in D drive pkzip xyz *.jpg Compress all JPEG files into the Zip archive XYZ.ZIP.
Interactive or Sequential
Commands can be executed one at a time by typing the command and pressing Enter. They can also be executed as a group, in which case the commands are typed into a "batch" or "script" file. The file name is typed on the command line, and pressing Enter causes each command to be executed in order. See batch file abc's, cmd abc's, command processor and PowerShell.
