00:00:06,900 --> 00:00:08,490
- We are now at the end of this lesson.

2
00:00:08,490 --> 00:00:11,160
Let's have a look at
commands that we have seen.

3
00:00:11,160 --> 00:00:14,700
It started with ln for creating
hard and symbolic links.

4
00:00:14,700 --> 00:00:16,230
Then we have used find,

5
00:00:16,230 --> 00:00:17,460
a convenient utility

6
00:00:17,460 --> 00:00:21,000
that allows you to find
files based on any property.

7
00:00:21,000 --> 00:00:24,930
Locate is convenient if you
want to be a little bit faster,

8
00:00:24,930 --> 00:00:27,660
but locate needs you to run updatedb

9
00:00:27,660 --> 00:00:29,820
because it works with a database.

10
00:00:29,820 --> 00:00:33,030
And which is finding files
that are in the path variable.

11
00:00:33,030 --> 00:00:35,790
So which is good for executables,

12
00:00:35,790 --> 00:00:37,230
but not for textiles

13
00:00:37,230 --> 00:00:40,350
or any other document
that you may have created.

14
00:00:40,350 --> 00:00:42,210
Tar was the utility that we have seen

15
00:00:42,210 --> 00:00:44,160
that you can use to archive files.

16
00:00:44,160 --> 00:00:47,400
And gzip is what you can
use to compress the file.

17
00:00:47,400 --> 00:00:49,230
After archiving,

18
00:00:49,230 --> 00:00:53,160
or you can call it directly
from tar using the z option.

19
00:00:53,160 --> 00:00:55,650
Now gzip was not the
only compression utility.

20
00:00:55,650 --> 00:00:59,520
We have talked about bzip2,
and xz, as well as zip.

21
00:00:59,520 --> 00:01:02,370
Of these utilities,
zip is not very common.

22
00:01:02,370 --> 00:01:04,710
Gzip is probably the most common.

23
00:01:04,710 --> 00:01:08,820
Bzip is giving a very
nice balance between time

24
00:01:08,820 --> 00:01:11,040
that it takes and compression ratio.

25
00:01:11,040 --> 00:01:13,290
And xz is what you wanna use

26
00:01:13,290 --> 00:01:16,800
if you want the best compression
that you can imagine.

27
00:01:16,800 --> 00:01:17,940
Now, we have seen file.

28
00:01:17,940 --> 00:01:21,000
File can be used on any
file to identify what type

29
00:01:21,000 --> 00:01:24,540
of file it is so that you
know what to do with it later.

30
00:01:24,540 --> 00:01:26,640
And last, we have talked about mount.

31
00:01:26,640 --> 00:01:30,090
Mount is how you connect a
device to a specific directory.

32
00:01:30,090 --> 00:01:33,090
Df is how you can see the mounted devices,

33
00:01:33,090 --> 00:01:35,433
including disk space still available.

34
00:01:37,020 --> 00:01:41,100
Findmnt is showing the
mounts in a nice overview.

35
00:01:41,100 --> 00:01:43,770
Findmnt is oriented on
the file system tree.

36
00:01:43,770 --> 00:01:45,780
So you can see where in the tree

37
00:01:45,780 --> 00:01:48,690
you have specific devices
that are mounted somewhere.

38
00:01:48,690 --> 00:01:51,480
And finally, we have talked about lsblk,

39
00:01:51,480 --> 00:01:54,183
which will list blocked
devices that are available.
