00:00:01,180 --> 00:00:08,340
In this video we're going to set up our terminal to look nice along our newly set up Sublime Text.

2
00:00:08,350 --> 00:00:14,620
As you know the terminal is just a text based way to communicate with the computer instead of the

3
00:00:14,620 --> 00:00:22,030
Graphical User Interface that we normally use. As developers you will spend a lot of time with the terminal.

4
00:00:22,030 --> 00:00:24,950
Especially as you become more and more senior in your role.

5
00:00:25,690 --> 00:00:27,070
So let's make it better.

6
00:00:27,970 --> 00:00:36,120
If we open up the terminal - I have it open already for myself, you see that we have the word 'bash' here.

7
00:00:36,120 --> 00:00:41,640
BASH is a type of shell that a terminal can have.

8
00:00:41,700 --> 00:00:43,480
And what do I mean by that?

9
00:00:43,740 --> 00:00:50,690
Just as the name suggests, it's just the casing around the terminal that is customizable.

10
00:00:50,700 --> 00:00:53,930
There's actually more than one shell.

11
00:00:53,940 --> 00:00:55,400
Bash is just one of them.

12
00:00:55,740 --> 00:00:58,320
One of my favorites are 'Oh my ZSH'.

13
00:00:58,360 --> 00:01:06,690
There's the 'Fish shell' and they all have different things that you can do with them,

14
00:01:06,690 --> 00:01:10,800
but it's just another way to customize your workstation.

15
00:01:10,800 --> 00:01:18,540
Before I get into that, let's just customize our 'bash'. The way we do that is we can first start off with

16
00:01:18,720 --> 00:01:25,680
getting something other than just having this to the left. The way we do that is we type in 'nano' 

17
00:01:25,800 --> 00:01:37,170
which is a text editor and then we do '~/.bash_profile'. And here what we open

18
00:01:37,200 --> 00:01:43,140
is a file that is the bash profile. So this is what our profile will look like.

19
00:01:43,140 --> 00:01:48,810
This file gets read every time we open up the terminal. In here we can put in a bunch of things that

20
00:01:48,810 --> 00:01:50,550
we want our terminal to do.

21
00:01:50,550 --> 00:01:58,560
One of the cool things that I really think is fun is updating your 'PS1' variable. And I'll link to

22
00:01:58,560 --> 00:01:59,540
this website.

23
00:01:59,940 --> 00:02:01,960
And there's a bunch of examples here that we can use.

24
00:02:01,960 --> 00:02:05,820
Let's just pick one that - like this one over here.

25
00:02:05,820 --> 00:02:09,090
All we do is copy and paste this.

26
00:02:09,300 --> 00:02:13,920
And within our bash profile we can just copy and paste.

27
00:02:14,150 --> 00:02:18,920
And as you can see our PS1 now equals a whole bunch of gibberish that we don't really need to worry

28
00:02:18,920 --> 00:02:19,390
about.

29
00:02:19,520 --> 00:02:25,220
We see over here that to exit we need to do Ctrl-X then save modified,

30
00:02:25,220 --> 00:02:28,230
we just press 'Y' and then press 'Enter'.

31
00:02:29,490 --> 00:02:41,030
OK, nothing happens but the way we fix that is we now do 'source' and then '~/.bash_profile'. It essentially reloads

32
00:02:41,030 --> 00:02:44,090
our profile now. And look at that.

33
00:02:44,270 --> 00:02:50,840
We now have a cool little prompt to the left. So you can set up your PS1 to display whatever you want.

34
00:02:50,840 --> 00:02:54,080
If you want to your current directory to display,

35
00:02:54,080 --> 00:02:56,210
that's great. If you want your username to display,

36
00:02:56,210 --> 00:02:57,870
that's good as well.

37
00:02:57,950 --> 00:03:00,400
You can set up in a ton of ways.

38
00:03:00,410 --> 00:03:05,670
The other thing that the terminal lets you do, if you click on something like a background color,

39
00:03:05,880 --> 00:03:09,070
You'll get a few things that you can change in your shell.

40
00:03:09,110 --> 00:03:12,910
You can change your color based on what you want.

41
00:03:13,280 --> 00:03:20,420
And if I bring this over here you can also click on the profile and actually it gives you a bunch of

42
00:03:20,600 --> 00:03:22,920
pre-built ones that look really cool.

43
00:03:22,940 --> 00:03:24,630
This is 'Pro' actually very nice.

44
00:03:24,800 --> 00:03:26,870
Again you can customize this as well.

45
00:03:26,900 --> 00:03:32,570
And as I mentioned a different operating system, you have your own ways to customize it.

46
00:03:32,810 --> 00:03:39,110
But every single one usually has a profile and a way to modify what gets displayed based on your needs.

47
00:03:39,110 --> 00:03:47,660
Now the one that I really really like, is a shell that's different than bash and I've used this one before

48
00:03:47,660 --> 00:03:51,670
which is really really good it has a ton of themes that you can use.

49
00:03:51,680 --> 00:03:54,100
They have a bunch of options and you can play through them.

50
00:03:54,230 --> 00:03:56,740
The one that I really like is the 'Fish Shell'.

51
00:03:56,750 --> 00:03:58,130
It's very simple.

52
00:03:58,160 --> 00:04:06,060
It has all the operating systems on it and I install it using 'homebrew'. For those on a Mac, Homebrew is

53
00:04:06,480 --> 00:04:09,060
a way to install anything from the web.

54
00:04:09,060 --> 00:04:15,090
So instead of me going to a website and installing something, I can use a command line to download things.

55
00:04:15,090 --> 00:04:21,660
If you go to the Homebrew website, brew.sh, You can actually just copy this link into your terminal

56
00:04:21,870 --> 00:04:22,740
copy and paste it.

57
00:04:22,740 --> 00:04:25,970
Press enter and it will install homebrew for you.

58
00:04:26,870 --> 00:04:34,140
I already have this installed, so I'll just exit that. The way I install fish -

59
00:04:34,180 --> 00:04:39,770
you can see over here all I have to do is say "brew install fish"

60
00:04:39,980 --> 00:04:45,550
And while this is happening, I want to show you another option. So we have the terminal over here,

61
00:04:45,650 --> 00:04:53,000
But 'iterm' which again is specific for Mac is really really nice and it's way more customizable than

62
00:04:53,000 --> 00:04:53,870
the terminal.

63
00:04:53,870 --> 00:05:05,010
So I prefer using 'iterm2'. If I open this and double click and look at that. This looks way nicer already.

64
00:05:06,650 --> 00:05:08,840
So let's just compare them side by side.

65
00:05:10,820 --> 00:05:13,950
I have my - let's make that a little bit bigger,

66
00:05:13,970 --> 00:05:19,770
I have the bash shell here and I have the fish shell here.

67
00:05:20,970 --> 00:05:27,500
Although they both are in the desktop right now they're running on different shells.

68
00:05:27,810 --> 00:05:34,730
The fish shell has - just like we have with the 'bash_profile', has its own profile.

69
00:05:35,220 --> 00:05:41,780
So you can set it up. And you can set up which one gets activated when you first open up the terminal

70
00:05:41,780 --> 00:05:49,170
or iterm. What I recommend is to set up your workstation in a way that's nice to you.

71
00:05:49,200 --> 00:05:54,030
My preferred way is to use iterm and the fish shell.

72
00:05:54,220 --> 00:05:56,680
But if you want to use bash that's great.

73
00:05:56,680 --> 00:06:03,340
The beauty here is that if I type in 'bash', I get taken to the bash profile. And if I type in 'fish',

74
00:06:03,340 --> 00:06:05,450
I get back to fish.

75
00:06:05,460 --> 00:06:12,310
iterm also lets you just customize everything really nicely. If I go to Preferences, you'll see here that

76
00:06:12,430 --> 00:06:19,690
I have Appearance, Profiles, where we can have Colors set up. And there's a ton more you can do with your

77
00:06:19,690 --> 00:06:25,160
terminal. But I won't get into in this video because everybody has their own way of doing things.

78
00:06:25,180 --> 00:06:34,470
I just wanted to show you a basic setup, so that now you have a nice environment that you can work at.

79
00:06:34,640 --> 00:06:36,510
I'll see you in the next one. Bye bye
