Command line interface : Command line
A command line interface or CLI is a method of interacting with a computer by giving it lines of text commands in written form either from keyboard input or from a script. The computer then generally responds with text output to the display or to a file. It contrasts with graphical user interfaces (GUIs).Examples of programs which use command line interfaces include the Unix shell, VMS DCL, and related follow-on designs like CP/M and MS-DOS's command.com. These programs are often called command line interpreters.
There are other programs which use CLIs as well. The CAD program AutoCAD has one. In some computing environments like Oberon or Smalltalk, most of the text which appears on the screen may be used for giving commands.
Even though new users seem to learn GUIs more quickly to perform common operations, carefully developed CLIs have several advantages:
- All options and operations are invoked in consistent form, while with GUIs similar operations often appear on different menus with different interfaces and different applications have different approaches.
- All options and operations are documented (or should be), meaning that it is no more difficult to perform a rare operation than a common one.
- CLIs double as scripting languages (see shell script) and can perform operations in a batch processing mode without user interaction. That means that once an operation is analyzed, it can be saved in a script and consistently performed without further effort. With GUIs, users must start over at the beginning every time, as GUI scripting is more limited (and often nonexistent). Simple commands do not even need a script, as the completed command can usually be assigned a name and executed simply by typing that name into the CLI.
As he had never enjoyed anything, he desired nothing
Chronic passion for cleaning
Devouring faith which is the making of martyrs and visionaries
Do you know.html">know how I picture God?
Don't know what to say, for I am always terribly stupid at first
Freemasonry made up of those who possess
Great ones of this world.html">world who make war
Hardly understand at all those bellicose ardors
How much excited cowardice there often is in boldness
Impenetrable night, thicker than walls and empty
Irresistible force of mutual affection
Key of a door
Legitimized love.html">love always despises its easygoing brother
Let them respect my convictions, and I will respect theirs
Love is always love, come whence it may
Love has no law
Machine for bringing children into the world
Moments of friendly silence
"My God! my God!" without believing, nevertheless, in God
One cannot both be and have been
Only being allowed to read religious works or cook-books
Pines, close at hand, seemed to be weeping
Presence of a woman, that sovereign inspiration
Purgatory and paradise according to the yearly income
Resisted that feeling of comfort and relief
She was an ornament, not a home
She saw that he would yield on every.html">every point
Spend his time quietly regretting the past
Subtleties of expression to describe the most improper things
Thin veneer of modesty of every woman
Unconscious brutality which is so common in the country
What is sadder than a dead house
When did you lie, the last time or now?
from the Short Stories of Guy de Maupassant, by David Widger
