Cyber Weapons Lab, Episode 209
Bash is a simple scripting language that's useful for chaining together various Linux tools without requiring you to learn any programming. In this episode of Cyber Weapons Lab, we'll use aliasing to call programs and then use Bash to automate tasks.

This is my kind of guy. His eyes tell me he's wasted no more than 3 hours sleeping since birth.
Pissed my pants lol
he's an EXPERT at what he does, and i like it.
@Badger anti R? Which programming language is that?
@@rikkertkuklinski4410 R is the language
@@aminechei8509 just be carefull. Dont piss the guy off. He might hack you while you're taking a dump and staring into your phone ...
I’ve watched a lot of technical training videos with 20 years in the industry.
You do a great job explaining things included with real live demos! Thank you for sharing what you do! Helping others learn too. 🙌🏼
Dude where have you been? I was about to call 911 and report you as missing. Glad you are back.
Oh wow false alarm for 911
Good luck at trials bro
@@KangJangkrik It was a joke.
@@kingseekerbackup3085 I know
The grim reaper pulled him into a dimension between space and time, to see who would blink first in exchange for his soul. Cody clearly won 👏👏👏
@@sprBEAST211 lmao
Great video. Exactly what a bash nab (me) needs to start up, see how to make a basic one then build on it, then add more and more and bit of polish ... brilliant.
I shortened that alias and implemented it into all my servers immediately (in my home) because it is simple and brilliant. I know them anyway because they are static, but I love the simplicity of it.
Just what I needed. I was literally just thinking about this! Thumbs up
Same bro, thought the algorithms recent update was to read my mind xD
just getting started with Linux Mint on a VM. This video just taught me so much. thank you :)
thanks from France!! I can't wait for the next video about bash scripting ! :)
I love your videos, can't thank you enough for what you do out here, and thanks for taking the time to "give us" this knowledge. Keep. Up the good work!
Studying for my Linux+, this is gold
You didn’t need the `echo $(`…`)` at the end, you just needed to escape the `$` so it doesn’t get expanded in the string: `alias ipaddress="ifconfig | grep broadcast | awk '{print \$2}'"`.
Thanks for this tip. It is more short and useful.
Phew I’m glad I’m not the only one that caught this. 😅😅
Fortunately for the civilized jq users among us, there is now “ip -json addr show | jq …”
No more ifconfig (I guess? Honestly I never got the ip tools memo, so this has been very confusing for me)
Writing bash scripts has saved me thousands of hours over the years. Thank you for the video, this is incredibly useful.
any real world sample you can share? thanks
@@charlesmagno28I got the same situation. For example - it really helps handle server apps, particularly deploy updates (or configs, patches), do system tasks
Thank you for showing the error you ran into and the work arounds in the video.
Thanks a lot, this is very well explained. It is the best explanation I have come across unlike many scripting/programming videos where the narrator often spends a lot of time even hours talking to themselves in vain because they are so badly explained.
Cool video- There is a lot of content like this on youtube but your style makes this easy to ingest for beginners. Couple if things though- You don't have to have .sh at the end of it and it you're going to run it with `bash ` you don't need the shebang either. Also, why did you have to fuzz the ifconfig command?
I hope you continue this series- bash offers some much more advanced capabilities.
Nice bash intro.
Half the battle when writing bash is knowing which command and arguments (flags) to pass to it;
# hostname -I
Returns the system primary IP address. Type hostname --help for details.
Of course, I understand the exercise was to demonstrate pipping capabilities of bash. But the less pipping the faster your script will run.
Also, this is much better than without the curly brackets.
# echo "${STRING}"
Excellent job.
You guys are reading my mind! This is EXACTLY the video I was looking for. This video is gold. More like this.
this is what i was gonna type in comment .....lol
@@sachinmaurya3259 I was going to type this too haha
@@dawidsadzak8137 sad u.u but great they made this video
@@dawidsadzak8137Way to devalue for the video for others my guy. If you don't get excited about this, you're in the wrong place.
@@dawidsadzak8137 True. I've seen a few. But it was a nice coincidence to watch this video today. I know how the world works, still, i think it's a great short video about things you can do with bash scripting.
Been trying to execute a bash file forever! First resource that actually helped!
This guy explains it better than my professor did last week
Are you taking computer science? Or IT
Lmaoo thx I will never go to university
I feel thee!!
Mine tooooo😅
@@cyberrock9018 which are you in?
Amaizing ,i did this tutorial on termux(android) , works like magic! Thanx alot!
I ENJOY your helpful interventions and your professional knowlege. TANK'S TOO MUCH.
I was looking exactly for this. Very nice content.
Amazing. Actually the advance commands was awesome
I taught my self this exact thing for batch scripting, time to learn bash!
Hey Kody, Thank you for your time and for your video
Great work man 😀 love your videos 👍
Thanks for sharing.
A minor correction, re 2:17 - the .sh extension is not actually necessary.
And just a note re 12:55, while some folks do call those "curly brackets", a less-confusing name for them would be "braces" -- { and } -- whereas "brackets" (or "square brackets") would be [ and ].
Awesome presentation! Thanks for the clarification.
My dad had me watch this video for a class I'm going to take. This looks interesting. I like coding.
Thanks man, you helped me a lot. I appreciate your work.
Last task was awesome..thnx man
A lot of power to the user. Very useful.
Thanks dude, great description.
Please continue this bash series.
Need more parts of it. 😍
Hello , très interessant ce tuto de découverte . J'ai apprécié vos explications et vous dis un grand merci pour ce partage .
Nice trick using a subprocess in an alias! Thanks
sick video , the alias thing is really cool.
From man bash: For almost every purpose, aliases are superseded by shell functions.
So no, aliases are not cool (apart maybe for just one command, but it gets crazy when you want to put more than one command with quotes; and also they can't handle arguments). Functions are cool!
woooow, Vibrasphere - Sweet september music on the beging.... I am delighted... :)
Holy crap, I'm shocked I actually know almost all of this. I was genuinely nervous thinking I forgot a lot of this stuff.
Amazing video. Ty Nullbytes
Yay I'm early - I love your videos man ❤
Even though it's quite a simple quide, it's great!
Thank you!
Excellent video brother
Nice~♡ dig the first ifconfig 🤣
This is good stuff mate 🧠👍
“Oops this isn’t python” hahah
"Kody"? Jackie is the punk. Thanks for shooting and sharing such a great tutorial.
Thank you so so much for this tutorial.
Intermediate Tip: Use "man bash" to learn the semantic differences of: "&" (ampersand), "&&" (double ampersand), "|" (bar), and ";" (semi-colon).
Most of my aliased commands use these punctuations, with one being "firefox & discord &" and another being "git fetch ; git status ;".
GL, HF
I enjoy your support. your work is very benefit. TANK'S.
well this was fun and educational thanks!
Well made! Thank you 😁
He stares the information into my soul.
This guy teach like a master.
AMazing video sir for beginners.
Thank you man for sharing this stuff
Thanks for the video
Please do make more videos for daily task automation
In the case of shebang, it's better to use `/usr/bin/env bash` instead of the exact shell location so it can be ram on different machines without changing a single line.
thank you :D
thats neat and smart tip, if i was to write malware on my linux machine and wanted to transfer to a remote machine somewhere else that might be using different shell. It could in cases like that then
Actually to find out the shell you are currently using you need to execute which $SHELL since most of the time you want your current shell to interpret your script
great video wish we could have more of
Argumentative bash script! hilarious :D
that cracked me up bro
Greatly appreciated sir!
Cool You really help me Well done!
Great timing 😁
I swear this is what I wanted
@Null Byte what that "Codes" book behind you?
Bash scripting in the new Windows Terminal is very useful.
Great work Mate. Keep Staring
Very well explained
Your videos are perfect to learn
That's very cool thanks!
Great video, thanks for sharing
hello . 0:40 It's get my attention that black blanket on the wall. The blanket surface is like the equipment on the voice lab to eliminate external sound effect. Am I right？
Good info, thank you.
Thanks for this video!
That's sweet! You can put target IP in $IP and bash scripting enumeration easily now
You made my life so much easier
This term, Linux, good timing❤️💋
I've been searching for a tutorial to make my terminal look like this, old green monitor, for a long time.
Do you have any tutorial for that?
I'm a complete newbie here in Brazil, learning Linux and Terminal prior to learn coding itself.
Thanks for the video.
didnt know th alias command. Thanks
do we have to edit with nano or is it cool to create the .sh files with vim?
The no-blink guy is back!
Lol
Bash was my entry point into coding!
I just wanted to save time on repetitive tasks and chill more while at work; upside was that I learned I could annoy my supervisor by being such a TryHard.
See but now they'll just give you more work if you prove yourself to be so efficient.
@@pianochannel100 yes if you ever make these kind of tweaks keep it to yourself and dont brag about it! :)
@@justinc4782 it depends where you want to go, to have a cushiony job with few working hours, then just quietly do your part.
If you want to be more successful and have a job that recognizes this effort, then ask for more work.
Any book recommendations to learn it more advanced?
I was going to comment to bash you for using nano but then I realized that I started doing anything on the *nix command line using nano instead of vi so I can't really say stuff; but vi is the best thing to learn.
Wow!!! Thank you!
Industrious intelligent geek. Awesome!
Would you do a similar video but with powershell?
Good video!
A person talking to his code is a brother. 😍😍😍
"belive"... Great video, as always, though.
Really cool! Thank you so much, Please make more cool videos like this...
Very informative
Can you have windows scheduler run a shell file as an admin? If so, how would you do that?
Really helpful video . Do you have any course on Udemy that I can purchase ?
Tks, Man!! pt-br!!
Why would I put a command (like whoami) into echo to get it to appear when I can just put whoami on a line in the script and it does the same thing?
Can you make a script for making post on social media as planed per user and on given time
Hi and thank you. You should make a complete serie on that
Good habits put in a "header" with the date, your name and purpose of the script.
Also keep upper case vars for env vars.
^^^ being kind to your future self
