LS

*de la JaMShooT

In computing, ls is a command to list files in Unix and Unix-like operating systems. ls is specified by POSIX and the Single UNIX Specification. When invoked without any arguments, ls lists the files in the current working directory.

So for example a process with working directory /rabbit-shoes that asks to create the file foo.txt will end up creating the file /rabbit-shoes/foo.txt.

In computing, a directory is a file system cataloging structure which contains references to other computer files, and possibly other directories. On many computers, directories are known as folders, catalogs (catalog was used on the Apple II, the Commodore 128 and some other early home computers as a command for displaying disk contents; the filesystems used by these did not support hierarchal directories), or drawer to provide some relevancy to a workbench or the traditional office file cabinet.

Files are organized by storing related files in the same directory. In a hierarchical filesystem (that is, one in which files and directories are organized in a manner that resembles a tree), a directory contained inside another directory is called a subdirectory. The terms parent and child are often used to describe the relationship between a subdirectory and the directory in which it is cataloged, the latter being the parent. The top-most directory in such a filesystem, which does not have a parent of its own, is called the root directory.

There is a difference between a directory, which is a file system concept, and the graphical user interface metaphor that is used to represent it (a folder).

In computing, a file system (or filesystem) is used to control how data is stored and retrieved. Without a file system, information placed in a storage area would be one large body of data with no way to tell where one piece of information stops and the next begins. By separating the data into pieces and giving each piece a name, the information is easily isolated and identified. Taking its name from the way paper-based information systems are named, each group of data is called a “file“. The structure and logic rules used to manage the groups of information and their names is called a “file system”.

There are many different kinds of file systems. Each one has different structure and logic, properties of speed, flexibility, security, size and more. Some file systems have been designed to be used for specific applications.

File systems can be used on numerous different types of storage devices that use different kinds of media. The most common storage device in use today is a hard disk drive, in which the media is a disc that has been coated with a magnetic film. The film has ones and zeros “written” on it by sending electrical pulses to a magnetic “read-write” head. Other kinds of media that are used include flash memory, magnetic tapes, and optical discs. In some cases, such as with tmpfs, the computer’s main memory (random-access memory, RAM) is used to create a temporary file system for short-term use.

A filename (or file name) is used to identify a storage location in the file system.

File systems typically have directories (also called folders) which allow the user to group files into separate collections.

command-line interface or command language interpreter (CLI), also known as command-line user interface, console user interface, and character user interface (CUI), is a means of interacting with a computer program where the user (or client) issues commands to the program in the form of successive lines of text (command lines).

In computer science, a graphical user interface (GUI), is a type of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, instead of text-based user interfaces, typed command labels or text navigation.

Designing the visual composition and temporal behavior of a GUI is an important part of software application programming in the area of human–computer interaction. Its goal is to enhance the efficiency and ease of use for the underlying logical design of a stored program, a design discipline named usability. Methods of user-centered design are used to ensure that the visual language introduced in the design is well-tailored to the tasks.

ex:

$ pwd
/home/fred
$ ls -l
drwxr--r--   1 fred  editors   4096  drafts(directory)
-rw-r--r--   1 fred  editors  30405  edition-32(regular file)
-r-xr-xr-x   1 fred  fred      8460  edit(executable)
$ ls -F
drafts/
edition-32
edit*

kinda... mai vreau exemple ca sa inteleg
n-am pe cine intreba daca am inteles corect informatia data
