1
00:00:06,480 --> 00:00:07,313
- All right.

2
00:00:07,313 --> 00:00:08,495
Let's have a look

3
00:00:08,495 --> 00:00:09,339
at the commands that we
have seen in his lesson.

4
00:00:09,339 --> 00:00:13,510
It all started with editors,
nano the easy editor

5
00:00:14,709 --> 00:00:17,130
or vimtutor, the best
way to prepare yourself

6
00:00:17,130 --> 00:00:18,603
for life with VIM.

7
00:00:20,202 --> 00:00:22,043
Then there is VI as well as VIM

8
00:00:22,043 --> 00:00:24,243
which both are basically the same editor.

9
00:00:25,140 --> 00:00:26,430
VIM is VI improved.

10
00:00:26,430 --> 00:00:28,710
VI is just the original editor

11
00:00:28,710 --> 00:00:33,450
as it was created in the, in 1984.

12
00:00:33,450 --> 00:00:37,140
You will appreciate VIM. And
in some cases, if you get

13
00:00:37,140 --> 00:00:39,990
to a real old system,
you might not find VIM.

14
00:00:39,990 --> 00:00:42,270
You can use vi instead.

15
00:00:42,270 --> 00:00:44,550
More is what you can use as a pager

16
00:00:44,550 --> 00:00:46,560
to see the contents of text files.

17
00:00:46,560 --> 00:00:48,690
And less is doing the same as more

18
00:00:48,690 --> 00:00:50,667
but just a little bit better way.

19
00:00:50,667 --> 00:00:53,650
Head is showing the top couple
of lines in the text file

20
00:00:53,650 --> 00:00:57,180
and tail, it's showing the
last lines in the text file.

21
00:00:57,180 --> 00:00:59,860
Now we have cat, which will
dump the entire text file

22
00:01:01,017 --> 00:01:03,060
and don't forget about
cat minus uppercase a

23
00:01:03,060 --> 00:01:05,583
which will print special
characters as well.

24
00:01:07,027 --> 00:01:09,288
And tac is printing a text
file in reverse order.

25
00:01:09,288 --> 00:01:11,583
And last we have talked about grep.

26
00:01:11,583 --> 00:01:15,930
Grep is the amazing utility
that allows you to find text

27
00:01:15,930 --> 00:01:17,913
in files as well as command output.
