cli full form in computer

Schedules commands and programs to run on a computer. Runs a specified command for each file in a set of files. Z shell is the default shell for macOS; bash, tcsh, and the KornShell are also provided. Displays messages, or turns command echoing on or off. Directs the Windows command interpreter to a labeled line in a batch program.

[12] One can also access the same commands from other command lines (such as the BBC BASIC command line), by preceding the command with a *. Unix also had the capability to save and re-run strings of commands as "shell scripts" which acted like custom commands. (They are, after all, interpreters of an interpreted programming language, albeit in many cases the language is unique to the particular command-line interpreter.) Many Unix systems feature the $PS1 variable (Prompt String 1),[11] although other variables also may affect the prompt (depending on the shell used). When a command processor is active a program is typically invoked by typing its name followed by command-line arguments (if any). The command line allows one to restrict available commands, such as access to advanced internal commands. Unix-based operating systems minimize the use of embedded spaces to minimize the need for quotes. Because it must satisfy both the interactive and programming aspects of command execution, it is a strange language, shaped as much by history as by design. Programs like BASIC, diskpart, Edlin, and QBASIC all provide command-line interfaces, some of which use the system shell. The Windows CMD.EXE does this. Shifts the position of replaceable parameters in batch files. [25][better source needed].
Begins localization of environment changes in a batch file. Command-line interpreters allow users to issue various commands in a very efficient (and often terse) way.


Although desirable at least for the help parameter, programs may not support all option lead-in characters exemplified above. CLI is a command line program that accepts text input to execute operating system functions. [35] This functionality is present whether the search is triggered from a browser field or on Google's website. Move one level up (one folder) in the file system. If the SwitChar has been changed to - and therefore the / character is accepted as alternative path delimiter also at the DOS command line, programs may misinterpret options like /h or /H as paths rather than help parameters.

(2) Short for Common Language Infrastructure. In the case of embedded systems, each vendor, such as Nortel, Juniper Networks or Cisco Systems, defines their own proprietary set of rules that all commands within their CLI conform to. alias md mkdir in tcsh). Examples of command-line interpreters include DEC's DIGITAL Command Language (DCL) in OpenVMS and RSX-11, the various Unix shells (sh, ksh, csh, tcsh, zsh, bash, etc. A few computer users used GUIs such as GEOS and Windows 3.1 but the majority of IBM PC users did not replace their COMMAND.COM shell with a GUI until Windows 95 was released in 1995.[26][27]. Data General's CLI under their RDOS, AOS, etc. The syntax is the grammar that all commands must follow.

In the case of Included or External commands, the values of the parameters are delivered to the program (specified by the Command) as it is launched by the OS. Under most operating systems, it is possible to replace the default shell program with alternatives; examples include 4DOS for DOS, 4OS2 for OS/2, and 4NT / Take Command for Windows. Such access was primarily provided to users by computer terminals starting in the mid-1960s, and continued to be used throughout the 1970s and 1980s on VAX/VMS, Unix systems and personal computer systems including DOS, CP/M and Apple DOS. For example, if the CLI had two modes called interface and system, the user might use the command interface to enter the interface mode. A CLI can generally be considered as consisting of syntax and semantics. [10] However, if given as first or only parameter, most DOS programs will, by convention, accept it as request for help regardless of the current SwitChar setting.

From the early 1970s the Unix operating system adapted the concept of a powerful command-line environment, and introduced the ability to pipe the output of one command in as input to another. The commands are stored in the graphical shell[clarification needed] or in files like the registry or the OS/2 OS2USER.INI file. In the bash shell, a prompt of the form: In zsh the $RPROMPT variable controls an optional "prompt" on the right-hand side of the display. Edits command lines, recalls Windows commands, and creates macros. However, CLI is still used by software developers and system administrators to configure computers, CLIs are often used by programmers and system administrators, in engineering and scientific environments, and by technically advanced personal computer users. This requires the user to know the names of the commands and their parameters, and the syntax of the language that is interpreted. Programs with command-line interfaces are generally easier to automate via scripting. Useful command lines can be saved by assigning a character string or alias to represent the full command, or several commands can be grouped to perform a more complex sequence – for instance, compile the program, install it, and run it — creating a single entity, called a command procedure or script which itself can be treated as a command.

In the 1960s, using only computer terminals, this was the only way to interact with computers. Many video games on the PC feature a command line interface often referred to as a console. [10] Some versions of DR-DOS COMMAND.COM also support a PROMPT token $/ to display the current setting. For example, all features of MATLAB, a numerical analysis computer program, are available via the CLI, whereas the MATLAB GUI exposes only a subset of features. Displays or modifies access control lists (ACLs) of files. Unix command names, arguments and options are case-sensitive (except in a few examples, mainly where popular commands from other operating systems have been ported to Unix). If more detailed help is necessary than provided by a program's built-in internal help, many systems support a dedicated external "help command" command (or similar), which accepts a command name as calling parameter and will invoke an external help system. Some computer language systems (such as Python, Forth, LISP, Rexx, and many dialects of BASIC) provide an interactive command-line mode to allow for rapid evaluation of code. c:\> hostname senthil-pc.

It is typically used by the game developers during development and by mod developers for debugging purposes as well as for cheating or skipping parts of the game. For example, is ambiguous (is "program name" part of the program name, or two parameters? Kill or stop a running process or application. Suspends processing of a batch file and displays a message. are not ambiguous. [10] Also, the current setting is reflected also in the built-in help screens. These advantages mean that a user must figure out a complex command or series of commands only once, because they can be saved, to be used again.
