00:00:06,639 --> 00:00:08,470
This video will talk
about more and less.

2
00:00:09,349 --> 00:00:12,310
So do you need more
or do you need less?

3
00:00:13,169 --> 00:00:15,000
More was the
original file pager.

4
00:00:15,660 --> 00:00:19,890
We call it a file pager because it allows
you to read the text file page by page.

5
00:00:21,050 --> 00:00:24,910
Now, in Linux, the latch utility
was developed to offer some more features.

6
00:00:25,579 --> 00:00:28,460
And as a reaction to that,
More was developed a bit more.

7
00:00:29,339 --> 00:00:31,320
But still, you can
do more with less.

8
00:00:32,240 --> 00:00:39,119
Does it make sense? It absolutely does. Less is the
default pager file in Linux. Let's do a quick demo.

9
00:00:41,340 --> 00:00:45,310
So I'm going to use
sudo less on var log messages.

10
00:00:45,810 --> 00:00:51,200
If you're on Ubuntu, you need to use sudo
less on var log syslog because they don't have messages.

11
00:00:51,880 --> 00:00:57,950
Now I am going to do what? Well,
I'm going to scroll down, scroll forward a little

12
00:00:57,950 --> 00:01:04,019
bit and hey, I want to know if
there's anything about ssh. So I'm using ssh.

13
00:01:05,900 --> 00:01:08,200
And look at
that. Messages about ssh.

14
00:01:08,739 --> 00:01:13,426
That's how you can use less to scroll
through a file. If you think that looks

15
00:01:13,426 --> 00:01:18,113
familiar. Yeah, there's a reason for it, and
that is because man and Less are based

16
00:01:18,113 --> 00:01:22,799
on the same backend. You could say
that man is built on top of Less.

17
00:01:23,060 --> 00:01:26,260
So the same key sequences
apply, like Q to quit.

18
00:01:27,250 --> 00:01:31,210
Now, one more thing
about less, and that's more.

19
00:01:31,210 --> 00:01:35,170
Let's use sudo more
on var log messages.

20
00:01:36,329 --> 00:01:42,310
There. I'm using spacebar to scroll down and
I'm using the arrow key to scroll up.

21
00:01:43,310 --> 00:01:45,859
That is one of the things
that more couldn't do in the beginning.

22
00:01:46,480 --> 00:01:50,489
Earlier versions of More, you could only
go down. That's why it's called more.

23
00:01:51,170 --> 00:01:55,049
It could only show you more of the
fell. It couldn't show you less of the fell.

24
00:01:55,549 --> 00:02:00,234
And when I say that More is
doing a little bit more than in the

25
00:02:00,234 --> 00:02:04,920
days before. Well, it's mainly about the
option to scroll up in your file.

26
00:02:05,700 --> 00:02:09,735
But in the end, more and Less are
pretty much the same. More or less, use

27
00:02:09,735 --> 00:02:13,770
cue to get out of here and
let's have a look at the next video.
