00:00:00,000 --> 00:00:01,929
[No audio]

2
00:00:01,929 --> 00:00:04,610
Linux versus Windows command.

3
00:00:04,610 --> 00:00:06,142
Why do we care about Windows

4
00:00:06,142 --> 00:00:08,468
when we're learning Linux. Right.

5
00:00:08,468 --> 00:00:11,024
Well, certain times you do have to get

6
00:00:11,024 --> 00:00:15,552
into Windows to work or to perform certain

7
00:00:15,655 --> 00:00:19,725
tasks that will transfer files from one location

8
00:00:19,725 --> 00:00:22,690
to another, or to run certain commands.

9
00:00:22,690 --> 00:00:24,500
So certain things that you would have

10
00:00:24,534 --> 00:00:28,510
to do eventually to work with Windows.

11
00:00:28,510 --> 00:00:31,785
But of course, mostly Windows is all GUI.

12
00:00:31,785 --> 00:00:33,931
But I think it's good that you should

13
00:00:33,931 --> 00:00:37,450
know certain differences between Linux and Windows.

14
00:00:37,450 --> 00:00:41,192
I will log into my Linux machine as well as

15
00:00:41,192 --> 00:00:45,476
I will bring up the Windows command line as well.

16
00:00:45,476 --> 00:00:49,009
What? Is there a Windows command line?

17
00:00:49,009 --> 00:00:53,000
Yes, there is, there is a Windows command line, but it

18
00:00:53,000 --> 00:00:57,631
is not purely used, just like as Linux is used.

19
00:00:57,631 --> 00:01:00,020
But there are certain commands that we will run in

20
00:01:00,020 --> 00:01:05,306
Windows that does some of the functions that Linux does.

21
00:01:05,510 --> 00:01:09,860
Here are the few commands that you will see that

22
00:01:09,860 --> 00:01:13,328
are pretty much works the same way as it works

23
00:01:13,328 --> 00:01:18,199
in Linux, but the name of the command is different.

24
00:01:18,199 --> 00:01:22,170
So listing of a file or directory in Linux is ls -l,

25
00:01:22,170 --> 00:01:26,804
in Windows it is dir. To rename a file is move in

26
00:01:26,804 --> 00:01:30,723
Linux and ren in Windows.

27
00:01:30,723 --> 00:01:36,231
Copy simply straight copy, copy, and in Linux it is copy, cp.

28
00:01:36,231 --> 00:01:40,902
move and mv, cls and clear.

29
00:01:40,902 --> 00:01:47,058
del which is to remove a file or remove a directory, and rm in Linux.

30
00:01:47,058 --> 00:01:53,750
fc is to compare two files, diff is to compare two files.

31
00:01:53,750 --> 00:02:02,190
find is to find something inside of a file, whereas grep does that in Linux.

32
00:02:02,750 --> 00:02:06,318
To get some help in Linux you get man, and to get

33
00:02:06,344 --> 00:02:12,729
some help in Windows, you run command slash question mark, sorry.

34
00:02:12,899 --> 00:02:16,259
And then we have display your location and file system,

35
00:02:16,259 --> 00:02:22,093
we do pwd and in Linux is change dir or chdir,

36
00:02:22,169 --> 00:02:24,626
I don't know how it is pronounced.

37
00:02:24,817 --> 00:02:27,059
And the last one we have date and time.

38
00:02:27,509 --> 00:02:31,029
Of course the commands do not stop here.

39
00:02:31,080 --> 00:02:33,214
There are many other commands, but I'm just giving

40
00:02:33,251 --> 00:02:36,322
you examples of few of them, that there are

41
00:02:36,455 --> 00:02:39,598
some command lines that Windows have put up over

42
00:02:39,623 --> 00:02:42,669
the years to compete with Linux.

43
00:02:43,289 --> 00:02:48,166
But everybody knows that Windows is primarily used

44
00:02:48,287 --> 00:02:51,565
because it's GUI based, and Linux is primarily

45
00:02:51,638 --> 00:02:56,266
used, in Linux, because it's terminal or command line based.

46
00:02:56,447 --> 00:02:58,813
And when you have a command line as opposed

47
00:02:58,861 --> 00:03:01,606
to GUI, GUI takes a lot of CPU, a

48
00:03:01,608 --> 00:03:04,294
lot of memory, and command line does not,

49
00:03:04,332 --> 00:03:08,050
so that's why Linux is so much faster.

50
00:03:08,490 --> 00:03:11,121
And then also with the command lines you can

51
00:03:11,136 --> 00:03:14,522
do so many things as opposed to Windows.

52
00:03:14,522 --> 00:03:16,850
So I'm going to log into my Linux machine, and

53
00:03:16,850 --> 00:03:21,970
run few commands, the ones that I highlighted, just to get

54
00:03:22,020 --> 00:03:26,578
to the lessons, and just to get to make

55
00:03:26,604 --> 00:03:29,578
you understand what exactly the difference is.

56
00:03:29,723 --> 00:03:34,690
So this is my command line in Linux, and

57
00:03:34,740 --> 00:03:36,358
I'm going to go over some of the ones

58
00:03:36,384 --> 00:03:40,225
that I have here, it is cls, and in Linux,

59
00:03:40,298 --> 00:03:44,914
so when I do ls -ltr, message come up. When I type

60
00:03:45,011 --> 00:03:50,520
clear, it clears the screen. In Windows I have this terminal open,

61
00:03:50,850 --> 00:03:56,218
if I type anything like this, hit Enter, Enter, Enter, or I could

62
00:03:56,244 --> 00:04:01,533
just cls and it clears the screen as well. Then I

63
00:04:01,632 --> 00:04:05,001
have other commands such as,

64
00:04:05,001 --> 00:04:08,548
[No audio]

65
00:04:08,548 --> 00:04:09,673
move the cursor,

66
00:04:11,057 --> 00:04:14,470
such as help, command slash,

67
00:04:14,470 --> 00:04:18,528
so if I have a command that I'm running let's say dir,

68
00:04:18,700 --> 00:04:25,002
then I'll hit slash and question mark. See

69
00:04:25,075 --> 00:04:29,238
it is giving me exactly, not exactly, but pretty much the

70
00:04:29,264 --> 00:04:35,973
same way as Linux does. And I do man on ls,

71
00:04:36,141 --> 00:04:41,394
this gives me the same help. Windows have actually catching up

72
00:04:41,432 --> 00:04:45,029
a lot of things on the command line just like for

73
00:04:45,140 --> 00:04:49,506
Linux, and the reason they do that they know that system

74
00:04:49,567 --> 00:04:54,558
administrator engineers who are really dealing with something very specific or

75
00:04:54,584 --> 00:04:57,138
something more robust or they wanted to get the result right

76
00:04:57,164 --> 00:05:01,730
away, they want to get into the command line. So to

77
00:05:01,730 --> 00:05:04,761
compete in the market, that's why they came up with these command

78
00:05:04,786 --> 00:05:09,773
lines. The next one I have chdir, which tells me which

79
00:05:09,812 --> 00:05:14,817
directory I am and in Linux what that command is pwd

80
00:05:14,854 --> 00:05:20,153
which directory I am. Then the last one is time, and

81
00:05:20,252 --> 00:05:23,898
in Linux is date, and it's time over there. I want

82
00:05:23,924 --> 00:05:28,641
you to run it yourself. Yeah, I think I should run it

83
00:05:28,656 --> 00:05:30,682
because there's one thing I do want to tell you that

84
00:05:30,756 --> 00:05:33,537
when you run time, it does give you a time, and

85
00:05:33,563 --> 00:05:36,394
then it prompts you to enter new time. Well

86
00:05:36,432 --> 00:05:38,398
you don't have to worry about it, so you just control

87
00:05:38,484 --> 00:05:41,338
C out of it, just like that you control C out

88
00:05:41,364 --> 00:05:46,906
of Linux machine. So these are a few things that you

89
00:05:46,967 --> 00:05:52,634
should know if you are getting into Linux job and Linux

90
00:05:52,682 --> 00:05:55,730
environment. It does not mean that you just going to forget

91
00:05:55,850 --> 00:06:01,858
everything about Windows. Windows has been there for a while, I

92
00:06:01,884 --> 00:06:04,966
would say it's a very good operating system in terms of

93
00:06:05,148 --> 00:06:10,473
desktop users who use it every day and of course most

94
00:06:10,511 --> 00:06:15,093
of the desktop market is captured by Windows, we should not forget that,

95
00:06:15,131 --> 00:06:17,029
we should give that credit to Microsoft

96
00:06:17,089 --> 00:06:22,234
of course, but in several environment where the higher level applications runs

97
00:06:22,272 --> 00:06:24,314
then of course Linux wins.
