Let's have a look at some useful tips and tricks and shortcuts when it comes to that.

2

One of the most common most useful signals that you can send your terminal is the commands.

3

Sometimes you'd be running a process or a program that you want to interrupt or you want to kill the

4

wait to do that is by using the Control see or demonstrate that using the command on Windows if you

5

remember when we did the command.

6

It stops by itself issues for pink packets and then it automatically stops and then next if other big

7

hackers like me that come there will continue engaging until I stop it myself.

8

It wouldn't stop automatically.

9

The way to do that is by the way Control C Control C is the command or the kill signal that I sent to

10

my terminal to tell it to stop or kill a program that's running.

11

Another option is to do the controlled Zeese fight on the command again and this time I don't want to

12

kill the program.

13

I just want to put it in the background because if you look at my terminal right now the pain is having

14

my terminal I can't type anything.

15

I can't continue work if I want my terminal back but I don't want to kill the command.

16

I can put it in the background by doing control Z.

17

I notice that now it says it stops.

18

So it's been suspended.

19

But it's not being killed.

20

If you look at the left side there's a number here.

21

This is the number of the program or the job that's been suspended and put in the background.

22

And this is useful if I want to bring it back to the foreground.

23

I can do f g or foreground and the number of the job that I put in the background that brings it back

24

to the foreground.

25

And it continues the process.

26

Now if I want to kill that what I do control see you know I have a lot of awkward and mess on my screen.

27

I want to clear it up.

28

The way to do that is by ensuring that your commands and this clears up my screen if I want to exit

29

my terminal.

30

I do exit.

31

I'm not going to do that now because I'm still working on it.

32

Here are some other useful tips.

33

The tab key is used for all to completion in Linux.

34

What this means is that if I start typing commands instead of me typing the whole thing I can just hit

35

the tab key and it will autocomplete that for me.

36

Now the thing you need to be careful with is that sometimes there are multiple options to one command.

37

So for example if I'm trying to do a traceroute and I start the tab key once nothing happens I'll have

38

to type it twice.

39

TAB TAB.

40

I noticed what happens here.

41

I get multiple options and they all start with Trace.

42

This is why the next one able to autocomplete that for me because I didn't know which one I wanted to

43

choose.

44

So I'll have to do a little bit more completion myself up with it and try again.

45

One of the completed recognizes that this is what I want.

46

Now that that command is useful not only for executing commands but for browsing directories it saves

47

me a lot of typing.

48

So let's say for example I want to work on a file and unmap for the under my documents folder under

49

my roof.

50

And to do that I wanted to see the.

51

Don't worry about what city means.

52

We learned that in a moment.

53

But instead of typing gurus I'll do our own tab instead of typing documents.

54

I do the Aussie tab instead of writing and map I do and and tab.

55

See how easy it is instead of typing all of that.

56

I'm going to delete that for now because we don't need that.

57

Here are some other tips for you to scroll up and down the screen instead of using the mouse.

58

If I don't have the graphical user interface and I don't have the mouse option I can do shift page up

59

and shift page down if I want to repeat previous commands instead of typing the whole thing again.

60

I can use the arrow keys I can to go up or down.

61

I can also look at my entire command history by issuing the history command.

62

Let's say I want to search one command to see what do I do.

63

I do control R and I type whatever I'm looking for.

64

Let's say I'm looking for and map and am a.

65

Notice how the output starts changing because it is trying to find the key word I'm looking for.

66

And here we go.

67

I found one with Unmap.

68

That was one of the commands that I typed earlier on.

69

And this by the way is a command that you slowly towards the end of the course.

70

Now if I hit enter it will execute the command for me.

71

It says No follow that entry because I'm working and this and that this is the way about the book.

72

Let's do another one under control or let's say for example I'm looking for the command.

73

Look at that B and it doesn't matter if once the command for me if I do enter it executes the command

74

for me or the Control-C to kill it.

75

Let's say for example I want to change the command to traceroute.

76

So instead of going back one letter at a time I can do control a to move to the beginning of the cursor.

77

And now I can change the command to traceroute.

78

For example instead of dot com I want to change it to dot or I can move to the end of the search using

79

control.

80

Another option I can use to delete the whole thing which is the same as the Cox command is the control.

81

OK now obviously for that to work I need to be at the beginning of the cursor which is control a and

82

then the control K was cut.

83

Or read the whole line.

84

This is more useful when I'm dealing with text editing but it still could be used on the terminal if

85

I want to base that back or use the Control wide wide stance for a Yank and if I want to clear my screen

86

I do control.

87

And that frees up my screen.

88

Great Experiment with those for.

89

Try them on yourself.

90

And then we can move on to the next session.
