00:00.460 --> 00:01.719
All right. Hello and welcome to

00:01.720 --> 00:02.720
Command Line.

00:02.800 --> 00:04.466
This video, this is our conclusion

00:04.660 --> 00:06.280
to the course, and we're going to go

00:06.400 --> 00:08.169
over and touch over everything we've

00:08.170 --> 00:09.787
learned so far and how we can use

00:09.970 --> 00:10.970
it. I'm Christopher.

00:11.230 --> 00:12.230
And let's begin.

00:12.970 --> 00:14.079
So we're learning objectives for

00:14.080 --> 00:15.459
this video. We're going to go over

00:15.460 --> 00:17.229
about how to open the command line,

00:17.350 --> 00:18.673
asking for help, navigating

00:19.510 --> 00:21.550
the file system at the Clie,

00:21.790 --> 00:23.309
using these common Seelie tools

00:23.890 --> 00:25.810
to perform these times and tasks

00:25.960 --> 00:27.459
and chaining together commands.

00:28.750 --> 00:30.230
So opening the command line.

00:30.250 --> 00:31.660
This is something we've learned

00:31.690 --> 00:33.258
where we're using it to interact

00:33.970 --> 00:35.709
with the system directly from the

00:35.710 --> 00:36.609
Seelie.

00:36.610 --> 00:38.319
And it's very similar to open it

00:38.320 --> 00:40.149
from Linux and from Windows as

00:40.150 --> 00:42.369
well. So you need to be comfortable

00:42.370 --> 00:43.987
with this and should be very easy

00:44.200 --> 00:46.179
to use asking

00:46.180 --> 00:47.709
for help. This is something that we

00:47.710 --> 00:49.278
talked about a lot and is such a

00:49.570 --> 00:51.459
critical part of using the

00:51.460 --> 00:52.419
CLI.

00:52.420 --> 00:53.259
Absolutely.

00:53.260 --> 00:55.359
Nobody remembers everything from

00:55.360 --> 00:56.360
the command line.

00:56.470 --> 00:58.389
Nobody remembers every switch

00:58.390 --> 00:59.390
for every command.

00:59.500 --> 01:01.329
And I'm constantly looking

01:01.330 --> 01:03.520
at the help or the manuals for

01:03.610 --> 01:04.610
different commands.

01:04.720 --> 01:05.847
And you absolutely need

01:06.760 --> 01:08.799
to use the Internet for research,

01:08.800 --> 01:10.659
asking for help, looking for how

01:10.690 --> 01:11.690
to manipulate

01:12.670 --> 01:14.319
different strings or manipulate

01:14.320 --> 01:15.639
different commands in order to

01:15.640 --> 01:17.499
become effective and

01:17.500 --> 01:18.529
to be able to do what

01:19.480 --> 01:20.949
you need to do from the command

01:20.950 --> 01:22.371
line. And like we were saying

01:22.540 --> 01:24.459
before, it is so important

01:24.550 --> 01:26.499
to be able to ask for help and read

01:26.500 --> 01:27.519
the documentation,

01:29.500 --> 01:30.909
navigating the file system.

01:31.060 --> 01:32.439
Hopefully you're very comfortable

01:32.560 --> 01:33.369
doing this.

01:33.370 --> 01:35.349
It's the same exact file system that

01:35.350 --> 01:37.016
you see in the GUI and we're going

01:37.150 --> 01:38.914
to use the change directory, the DIR

01:39.130 --> 01:40.747
and the commands in order to move

01:41.020 --> 01:42.099
through the different folder

01:42.100 --> 01:43.521
structures and be able to see

01:43.990 --> 01:45.880
what's inside of each folder and

01:46.000 --> 01:47.589
the different types of files and how

01:47.590 --> 01:48.590
we can use them.

01:50.230 --> 01:52.029
And using the sealife or timesaving

01:52.030 --> 01:53.108
test, first of all, we

01:53.920 --> 01:56.199
need to accomplish or identify

01:56.200 --> 01:57.964
what we need to accomplish, and then

01:58.420 --> 01:59.743
after getting this exposure

02:00.400 --> 02:01.920
for all these different tools, we

02:01.930 --> 02:03.159
need to make sure we're using the

02:03.160 --> 02:04.819
correct tool for the job.

02:05.260 --> 02:07.089
And then beyond the need to sort

02:07.090 --> 02:08.805
through the output from these tools

02:08.949 --> 02:10.629
and be able to look through and

02:10.630 --> 02:12.051
identify what we need for the

02:12.460 --> 02:13.449
output.

02:13.450 --> 02:15.165
And we can pipe these together, use

02:15.520 --> 02:17.186
different commands, given right or

02:17.350 --> 02:19.090
bad scripts, read our shell script

02:19.450 --> 02:21.669
and get what we need to be done

02:21.670 --> 02:23.409
very quickly and effectively.

02:24.910 --> 02:26.979
Choosing to give the commands type

02:26.980 --> 02:28.449
commands together, use the

02:28.450 --> 02:30.699
ampersand, use the different

02:30.700 --> 02:32.023
redirection operations, and

02:32.800 --> 02:33.976
we can save so much time

02:35.050 --> 02:37.119
using these different techniques

02:37.120 --> 02:38.559
in order to search through the

02:38.560 --> 02:39.981
output of commands, pipe them

02:40.270 --> 02:42.129
together, execute different things

02:42.130 --> 02:44.259
together and become very

02:44.260 --> 02:45.669
effective at what we do.

02:45.700 --> 02:46.876
Saves so much time using

02:47.680 --> 02:49.389
the command line instead of the

02:49.390 --> 02:50.390
gooey.

02:51.490 --> 02:52.899
And we also have additional

02:52.900 --> 02:54.759
resources for the

02:54.760 --> 02:55.539
command line.

02:55.540 --> 02:57.189
I highly recommend looking at other

02:57.190 --> 02:58.190
Siberry videos.

02:58.270 --> 02:59.500
If you enjoyed this one

02:59.770 --> 03:01.269
specifically, if you're not very

03:01.270 --> 03:02.679
comfortable with Linux, I highly

03:02.680 --> 03:04.209
recommend looking at the Linux plus

03:04.210 --> 03:05.739
videos so you can learn more about

03:05.740 --> 03:07.419
that and how to use it as you grow

03:07.420 --> 03:09.509
within your cybersecurity career.

03:10.030 --> 03:12.009
The Linux manuals are so important

03:12.010 --> 03:13.431
as well as you're using Linux

03:13.840 --> 03:15.699
commands, it's very, very

03:15.700 --> 03:16.869
critical to read through the

03:16.870 --> 03:19.089
manuals. Take your time, understand

03:19.090 --> 03:20.949
exactly how these commands

03:20.950 --> 03:22.714
work and usually they have some very

03:22.720 --> 03:24.000
excellent documentation.

03:24.610 --> 03:26.319
The Saints cheat sheets are very

03:26.320 --> 03:27.888
useful and give some really good

03:28.210 --> 03:29.876
information about how to use these

03:30.100 --> 03:32.409
commands and the most common

03:32.410 --> 03:33.410
types of switches or

03:34.360 --> 03:35.979
uses for these commands as well.

03:35.980 --> 03:37.479
And I highly recommend printing them

03:37.480 --> 03:39.789
out, highlighting the specific

03:39.790 --> 03:41.229
areas you're going to use the most.

03:41.770 --> 03:43.419
And like I said, the Internet is

03:43.420 --> 03:45.339
such a great resource for everything

03:45.340 --> 03:46.761
else. If you don't know how a

03:46.810 --> 03:48.639
specific command works or you need

03:48.640 --> 03:50.110
to look up more information, I

03:50.380 --> 03:52.119
highly recommend using the Internet,

03:52.120 --> 03:54.009
searching, looking on Google

03:54.040 --> 03:55.509
and using that for what you need to

03:55.510 --> 03:56.510
do.

03:57.310 --> 03:59.139
So in this video, we touched

03:59.140 --> 04:00.459
on how to open the command line

04:00.460 --> 04:02.077
again, how to ask for help at the

04:02.230 --> 04:03.879
terminal and why help is so

04:03.880 --> 04:04.759
important.

04:04.760 --> 04:06.869
Understand how to navigate the file

04:06.880 --> 04:08.469
system with the Seelie

04:09.040 --> 04:10.889
using the common tools

04:10.900 --> 04:12.610
for perform timesaving tasks

04:12.940 --> 04:14.770
and chaining together commands.

04:15.100 --> 04:16.717
And I'm so glad that you chose to

04:16.839 --> 04:18.849
take my course and I hope to see you

04:18.850 --> 04:20.679
in future Siberry videos later.
