1
00:00:00,980 --> 00:00:05,870
‫Now, a shell is a user interface for access to an operating system services.

2
00:00:06,350 --> 00:00:09,650
‫So in other words, if the user wants the operating system to do something.

3
00:00:10,550 --> 00:00:13,280
‫They will then use a shell for this purpose.

4
00:00:14,000 --> 00:00:21,800
‫It's a command language interpreter that executes commands, read from input devices such as keyboards

5
00:00:21,800 --> 00:00:23,240
‫or even from files.

6
00:00:24,970 --> 00:00:32,230
‫So in general, operating system shells use either a command line interface, seelye or graphical user

7
00:00:32,230 --> 00:00:33,640
‫interface DUI.

8
00:00:34,740 --> 00:00:41,460
‫Command line shelves called Terminal and Linux and Mac OS or command prompt in Windows.

9
00:00:43,590 --> 00:00:51,120
‫Graphical shelves provide means for manipulating programs based on graphical user interface, or GUI

10
00:00:51,690 --> 00:00:59,280
‫by allowing for operations such as opening and closing, moving, resizing windows as well as switching

11
00:00:59,280 --> 00:01:00,660
‫focus between windows.

12
00:01:01,610 --> 00:01:07,910
‫Now, its name is Shell, because it's the outermost layer around the operating system kernel.

13
00:01:10,130 --> 00:01:18,950
‫The colonel is a computer program that is the core of a computer's operating system with complete control

14
00:01:18,950 --> 00:01:24,560
‫over everything in the system, so it'll manage the following resources of the Linux system.

15
00:01:25,980 --> 00:01:26,970
‫File management.

16
00:01:27,860 --> 00:01:29,030
‫Process management.

17
00:01:30,090 --> 00:01:31,680
‫Input output management.

18
00:01:32,850 --> 00:01:37,050
‫Memory management, device management, et cetera, et cetera.

19
00:01:38,720 --> 00:01:46,700
‫Now, there are several shelves for Linux, such as ticks each K Yes, H and Z s h.

20
00:01:47,930 --> 00:01:51,230
‫But one of the more common ones is Bash.

21
00:01:52,260 --> 00:01:56,220
‫Where the name is an actual acronym for Born Again, Shell.

22
00:01:57,640 --> 00:02:02,800
‫So each shell does the same job, but it understands different commands and provides different built

23
00:02:02,800 --> 00:02:03,520
‫in functions.
