Linux is sooo offensive. I think we should replace the 'sudo' command with pretty_please or something like that. What if the PC doesn't feel like executing the command? At this point, sudo-ing can be considered rape.10

Biggest terminal hack I've discovered till now which is so fucking obvious I can't believe I literally just started using it:
Executing the date command right before and after another command/series of commands to see how long shit takes.
$ date; command or commands; date
This is incredibly useful when rendering loads of data in screen sessions!
I actually feel rather retarded for only thinking of this now.17 -

Here is a preview of my Python devRant client
The client supports both CLI and GUI modes.
This is the CLI mode using the rant command.
CLI mode currently supports dynamic importing of custom commands (and creating your own command is documented already too).
If you do not like my rant command? Download or make another one.
Also, the command execution, import, and registration process all send events to the application object. This is in preparation for allowing mods!
Unfortunately, emojis are technically 2-width, so they totally fuck up the box I draw around the rant. Lots of work to do, but I was pleased with my first visual payoff today.

Anyone else having connection problems after the recent Windows 10 update? We've been slammed at work with them. If you do, here's an easy fix:
0. Go to Command Prompt (Run as Administrator)
1. First command:
netsh int ip reset resetlog.txt
(One of them will probably fail, that's fine.)
2. Second command:
netsh winsock reset
3. Restart the computer.13 -

Knowing the Linux command line saved my bacon!
I was on a plane, unable to connect to wifi, and needed to take a note... while not having any note taking applications or text editing applications on my phone. but what I DID have was a terminal application.
So, I made a file in my documents folder and echoed my notes into the file! A bit longer and more complicated than it needed to be, but it worked when I needed it to!12 -
When I was about 13, I opened up command prompt on Windows, and changed the color of it to green then ran the tree command. So, not thinking of anything, this was in the library in front of about 60 people and 2 teachers.
All others saw was green text going down fast, and instantly presumed that I was hacking since they knew I was into coding and finding exploits, and just knew how to use a computer better than them in simple terms (HACKER MAN). Thus this lead to me getting sent to the principal's office... I almost got suspended cause I ran the tree command in green.
Two questions for me remain unanswered, that I would love to know. What would've happened if command prompt was printing text in red. Another question becomes, what would've happened if people saw me pinging Google or some popular site.4 -

Oh God.
So I'm working on something and I needed to see how it looks when you type a command into the terminal (like the animation).
Quickly Google "Kali linux terminal," since it's kinda where I'm getting some of the design from.
First video "Kali Linux basic commands (every ethical hacker must know in 2018)"
1st command: whoami
2nd command: date
3rd command: pwd
4th command: cd
5th command: ls
I'd say that's a wee bit basic there and those are commands that literally anyone who touches linux should know, dontcha think there pal?

VIM! ViM! vim! Vi Improved! Emacs (Wait ignore that one). What’s this mysterious VIM? Some believe mastering this beast will provide them with untold mastery over the forces of command line editing. Others would just like to know, how you exit the bloody thing. But in essence VIM is essentially a command line text editor at heart and it’s learning curve is so high it’s a circle.
There’s a lot of posts on the inter-webs detailing how to use that cruel mistress that is VIM. But rather then focus on how to be super productive in VIM (because honestly I’ve still not got a clue). This focus on my personal journey, my numerous attempts to use VIM in my day to day work. To eventually being able to call myself a novice.
My VIM journey started in 2010 around the same time I was transiting some of my hobby projects from SVN to GIT. It was around that time, that I attempted to run “git commit” in order to commit some files into one of my repositories.
Notice I didn’t specify the “-m” flag to provide a message. So what happened next. A wild command line editor opened in order for me to specify my message, foolish me assumed this command editor was just like similar editors such as Nano. So much CTRL + C’ing CTRL + Z’ing, CTRL + X’ing and a good measure of Google, I was finally able to exit the thing. Yeah…exit it. At this moment the measure of the complexity of this thing should be kicking in already, but it’s unfair to judge it based on today’s standards of user friendly-ness. It was born in a much simpler time. Before even the mouse graced the realms of the personal computing world.
But anyhow I’ll cut to the chase, for all of you who skipped most of the post to get to this point, it’s “:q!”. That’s the keyboard command to quit…well kinda this will quit the program. But…You know what just go here: The Manual. In-fact that’s probably not going to help either, I recommend reading on :p
My curiosity was peaked. So I went off in search of a way to understand this: VIM thing. It seemed to be pretty awesome, looking at some video’s on YouTube, I could do pretty much what Sublime text could but from the terminal. Imagine ssh’ing into a server and being able to make code edits, with full autocomplete et al. That was the dream, the practice…was something different. So I decided to make the commitment and use VIM for editing one of my existing projects.
So fired the program up and watched the world burn behind me. Ahhh…why can’t I type anything, no matter what I typed nothing seemed to appear on screen. Surely I must be missing something right? Right! After firing up the old Google machine, again it would appear there is this concept known as modes. When VIm starts up it defaults to a mode called “Normal” mode, hitting keys in this mode executes commands. But “Insert” entered by hitting the “i” key allows one to insert text.
Finally I thought I think I understand how this VIM thing works, I can just use “insert” mode to insert text and the arrow keys to move around. Then when I want to execute a command, I just press “Esc” and the command such as the one for saving the file. So there I was happily editing my code using “Insert” mode and the arrow keys, but little did I know that my happiness would be short lived, the arrow keys were soon to be a thorn in my VIM journey.
Join me for part two of this rant in which we learn the untold truth about arrow keys, touch typing and vimrc created from scratch. Until next time..

Hiii devRanters, I have a TypeScript question for you...
How do I dynamically import classes?
I have a class like this:
export default class Foo implements Bar {
...
....public getName(): string {
........return this.name;
....}
}
and then I have another file with this:
import(`./class-cmd/${file}`).then((command) => {
....winston.debug(command);
....winston.debug(command.getName());
});
the first command spits out something like this:
debug: default=class Foo {
....constructor() {
........this.name = "foo";
....}
....getName() {
........return this.name;
....}
}
and I would expect that the second command will work, however it throws this:
UnhandledPromiseRejectionWarning: TypeError: command.getName is not a function
Any idea what I might be doing wrong?18 -

Wanted to know it's dependency version:

I found the best text editor for basic code fixing
For a couple of days, I was looking for a simple terminal-based text editor for taking simple code notes or basic code fixing kinds of stuff.
As an aspiring developer, I really like the concept of coding without touching the mouse.
So I downloaded the king of CLI text editors, Vim.
Now, guess what happened.
Yeah, you're right. I stuck inside vim and couldn't even quit from there.
Then, I started watching a bunch of tutorials and started reading vim's documentation.
But then I realized, I have to learn a lot of things only to operate vim and it's a pretty lengthy process.
At that time, I really needed a very simple text editor for doing basic stuff.
But, vim is not simple... you know :)
So, I had to come back to 'nano' & I was not happy enough to write codes by using 'nano'.
Suddenly, I discovered another really cool text editor called 'micro'.
It's really awesome.
It's not as advanced as vim but definitely a lot better than nano.
Micro is an open-source command-line text editor created by Zachary Yedidia.
Some basic key points of Micro:
1. It's really easy to operate.
2. It has different colours and highlights.
3. It supports syntaxes for over 70+ programming languages.
4. It has mouse support.
5. Plugins & colour schemes.
The best thing for me is colour schemes & screen split support.

#TIL that you can navigate part of your Linux commands with CTRL like CTRL+A gets you to the beginning of the typed command, CTRL+D deletes the forward command and CTRL+E gets you to the end of the typed command.
NONE OF THIS WAS FOUND IN ANY LINUX-FU LESSONS! THESE WERE WAY EASIER TO USE THAN USING THE ARROW KEYS GODDAMMIT!2 -
Command Prompt is archaic and useless. The most I can do with it (without using other programs) is copy files and overwrite user passwords. Both useful, granted, but nothing compared to the Windows GUI - or, like, any other command line? Heck, I'd rather just have a python shell and nothing else.

I try map my Capslock key to ctrl key while using vim and I search for this on stackoverflow and I found
```Linux? With X, use xmodmap to alter the key mapping, e.g.
xmodmap -e 'clear Lock' -e 'keycode 0x42 = Escape'
Will map Esc to the CapsLock key. Google for more examples.```
following command it will map Esc key to CapsLock key but when I run this command my CapsLock key did stop working and nor my esc key map to CapsLock key. How do I get back my Capslock key default working state, I mean I don't want to map Capslock key to ctrl key?7 -

I don't know how to avoid the bug(?) described at the bottom.
Last time when I made one, used a line break, but whenever I went back in the command history and there is a long command (chain) it just messes up whole PS1 by getting inside, pressing backspace furiously to get the start of the command (mostly eating half of the PS1) and an up and a down to get back to command and see it properly.
Any good ideas to destroy that bug while it isn't born yet?1 -

What's the minimal feature set that can make a language as ornamented as JS into a comfortable REPL?
Should I write a full parser or should I try to patch my way around with regex?
It will have to interface a lot with JS so it has to be able to manage JS datastructures in some fashion, which means that I can't just make a whole new command line with its own programs.
My current plan:
Some delimiter (probably a semicolon) will take the output of a command and inject it in the next in case you decide halfway through a line to do some more processing, It also awaits promises and does some other nice stuff to make controlling such pipelines easy. I have an elaborate system in mind to decide where a value must be injected to make the line valid so in most cases you don't even have to indicate it. JS has beautifully simple syntax rules so I have a lot of technical balance to burn before I start building technical debt.
I have some ideas for automatic parentheses and commas in function calls. I realize while using a command line you do not want to tap shift often. My main idea here is that two names or values in js are always joined by an operator so the first missing operator is a call and following missing operators are commas until the end of line. This has lots of nasty edge cases though, like that no argument expression can begin with a unary operator or a bracket of any shape. You can always prepend a comma but it's cognitive load.
Anyway, do you have any suggestion or warning besides "js bad" which I know but it's the most popular sandboxable language and has a massive existing set of libraries which I kinda need.3 -
Does anyone have any recommendations for command line parsers for Python? I've looked at argparse click docopt so far. I am clearly bad at making informed decisions.
