A friend of mine once went into a library and opened a cmd on one of the computers, to run a little batch rename script on his usb stick. 5 minutes later he got kicked out because they though he was hacking the computer 😅4

A friend called ITIS guys about some network issue on his system.
Frnd : Hi, I'm facing some security policy issues on my system. Could you help me connect?
ITIS guy: Ok. Please run 'gpupdate /force' cmd from cmdpromt.
Frnd: Well actually I'm on Linux.
ITIS guy: Well, at least give it a try and tell me how it goes.
*Facepalm*? *Bodypalm*? Murder?4 -
Taught my whole team that you can enter cmd/bash commands directly into windows explorer in the location bar.
No point in opening git bash to just clone a repo or open cmd just to run a php server.8 -
Dad: God I hate Windows!
Me: Why? You know you can just run the getmac command in CMD, right?
Dad: What? There is a command for that?
Needless to say, my dad is not a network engineer...1 -
My idiot friend nearly destroyed his install because of me.
He was complaining to me about some program he was running in terminal writing too much lines to terminal he didn't care about.
So I wrote to him verbatim:
"Just redirect the output to /dev/null by running it like ```cmd > /dev/null```.
Or better yet do ```cmd > /dev/sda``` it will be more fun ;)"
Three minutes later I get a screenshot from him where he's trying to run ```cmd > /dev/sda```, but it keeps saying Permission denied. He's tried to use sudo in the screenshot like million different ways.
Thank god he doesn't know how to use sudo with redirects...12 -
I love how my University CSSE courses make it hard for Windows users.
Student: Is it possible use VALGRIND in Windows CMD?
prof: I don't know, I only use Linux command line. Next question.
All programs must compile and run on Linux using g++. So everyone using windows has strip the IDE bloat and transfer the project files over to the remote Linux lab every single time they compile and run.
Benefits of being a Linux user!5 -
Seriously, you can watch star wars in command prompt
Run this command in your cmd - telnet towel.blinkenlights.nl
But, this will not work in git bash ;)17 -
Spent the last half hour helping my wife over text trying to "fix" FireFox. She said any site she tries to go to just "spins and spins". Chrome, Edge, all work fine. Tried the trusty 'ipconfig /flushdns'.
Me: "Open the command line, by selecting Start and start typing cmd. You'll see the Command Prompt application. Right click and run it as an administrator"
<15 seconds later>
Her: "Do I left click or right click to run as adminstrator?"
Me: "Left click. You'll get a pop message, just click yes"
<about 10 seconds later>
Her: "This thing popped up, what do I do?"
Me: "Click yes"
<more waiting>
Her: "Says something about making changes to my computer, what do I do?"
Me: "Click yes"
Her: "Is it going to make changes? Are you sure I should click yes?"
Me: "YES!!"
Her: "Don't yell at me. You're supposed to know how to do this, not me. What do I do now?"
Me: "Type ipconfig /flushdns"
Her: "OK, is this right.."
<sends a screenshot of 'Type ipconfig/flushdns'>
Me: "No, just ipconfig /flushdns"
Her: "OK, is this right.."
<sends a screenshot of 'ipconfig/flushdns'>
Me: "Yep, just put a space between ipconfig /flushdns and press enter"
Her: "Is this right.."
<sends a screenshot of ' ipconfig/flushdns'>
Me: "No, the space goes between ipconfig /flushdns, not before."
Her: "You're not making yourself clear. OK, now what?"
Me: "Press enter"
Her: "It didn't do anything."
Me: "Did you press enter?"
<more waiting>
Her: "OK, it's done. Now what?"
Me: "Restart FireFox"
Her: "Still not working. Just spins and spins."
<not 100% sure restarted FireFox>
Me: "I'll look at it when I get home."17 -
We have a bunch of legacy applications that runs on Windows only. I'm pretty much the only dev here who doesn't use a Windows machine.
In order to run those applications, I need use remote desktop to a Windows VM.
I use a Mac. And I use a lot of keyboard shortcuts. Case in point, CMD + L to go to the address bar in the browser.
This happens every time when I need to access those applications.
me: *remote desktop to the VM
me: "oh I need to get to the index/landing page"
me: *CMD + L
VM: "I'm locked now"8 -
!Rant #lazy
I setup my local server so I can test my apps and to mount my partitions on my www folder in a folder named "mnt" with numbered folders for each mounted partition
So I can access and download my files to phone and other devices from all over the network :)
And even watch movies that are in my computer on my phone or tv
And when I want to sleep I usually watch a movie or one episode of series which is stored in my pc ,on my phone by this method in my bed 😅
So the thing is I'm too lazy to get out of bed and shut down the server and pc
So I setup this file so I can run commands on my PC from my phone 😅😂😂😂

My life was troublesome today, had to help a non programmer to run jar files.
The jar executed well from command line in Windows 10 but didn't work on double click.
Did all the tricks, registry edits, cmd commands and at last I found a miracle tool called Jarfix.
Just double click and all okay.
The root cause of the problem was 7zip.
This bug is reported in the Oracle bug reporting and they have closed it as " Will not fix" low-priority report.2 -
IDK man, it took me a while to finally learn iptables and now switch to firewalld? Oh come on. It's not that I'm against learning new things, no. It's just that firewalld looks a bit.. crappy. If I get a server provisioned and run
firewall-cmd --add-port=53/udp --permanent
firewall-cmd --reload
and I get my ssh connection killed that's no good news, no sir! I mean come on, how can I rely on a tool this critical when a single line in its config file can make my machine inaccessible. Even better -- this config file is managed by that tool entirely!!! My commands passed all the tool's checks and they worked, but when I wanted to make those commands permanent and reload state from the config -- the tool starts spitting bile and blood and says "fuck off, it's my server now!"
IDK man.. It's just way too fishy. The good ol' iptables works very well and I'm kicking its retard younger brother out of the server.
shoosh you dirty pig firewalld, shoosh!6 -
Don't quite get this.
There's some bug where u run sudo -u#-1 cmd, it lets you run it as root.
But then it says only if you have permission to do so.
Does that just mean "run sudo" or something else?
I'm thinking sudo -u#-1 /bin/bash would basically give anyone root?

I JUST REALISED HOW POWERFUL ARE COMMANDLINE ARGUMENTS !!
F*** you college u didn't teach me shit,they just taught us how to pass cmd arguments.
I just tried on my own to pass a command using PHP to run a simpe python script on the server! But its so fun!
Damn,now I see a sea of possibilities of what I can do with this new Power I discovered !!1 -
I hate that when developing on Windows I need like four different terminals. CMD, MINGW64/Cygwin/MSYS2, PowerShell. Each one has different functionality:
CMD - basic Windows commands
MINGW64 - emulates Linux terminal with frequent Linux commands and great support for Git
Powershell - access Windows COM, .NET etc.
Now there are solutions that attempt to solve this like Cmder (which is just more user-friendly ConEmu). These are console emulators which wrap all these in one window (with multiple tabs). But they are slow as hell. I have to wait like 10 seconds each time I start a terminal in Cmder, because the emulators need to run some huge startup scripts. But I just need to run one command from this one freaking folder!
Eventually I end up having like 30 different terminal windows open, each one different in functionality and each time I need to do something I must think about which terminal I need and in which folder. Furthermore I have to think about whether to run the terminal as administrator, but I usually forget that, so I have to close the terminal and reopen as admin. Why don't you just add something like su or sudo, Microsoft?

I hate the elasticsearch backup api.
From beginning to end it's an painful experience.
I try to explain it, but I don't think I will be able to cover it all.
The core concept is:
- repository (storage for snapshots)
- snapshots (actual backup)
The first design flaw is that every backup in an repository is incremental. ES creates an incremental filesystem tree.
Some reasons why this is a bad idea:
- deletion of (older) backups is slow, as newer backups need to be checked for integrity
- you simply have to trust ES that it does the right thing (given the bugs it has... It seems like a very bad idea TM)
- you have no possibility of verification of snapshots
Workaround... Create many repositories as each new repository forces an full backup.........
The second thing: ES scales. Many nodes / es instances form a cluster.
Usually backup APIs incorporate these in their design. ES does not.
If an index spans 12 nodes and u use an network storage, yes: a maximum of 12 nodes will open an eg NFS connection and start backuping.
It might sound not so bad with 12 nodes and one index...
But it get's pretty bad with 100s of indexes and several dozen nodes...
And there is no real limiting in ES. You can plug a few holes, but all in all, when you don't plan carefully your backups, you'll get a pretty f*cked up network congestion.
So traffic shaping must be manually added. Yay...
The last thing is the API itself.
It's a... very fragile thing.
Especially in older ES releases, the documentation is like handing you a flex instead of toilet paper for a wipe.
Documentation != API != Reality.
Especially the fault handling left me more than once speechless...
Eg:
/_snapshot/storage/backup
gives you a state PARTIAL
/_snapshot/storage/backup/_status
gives you a state SUCCESS
Why? The first one is blocking and refers to the backup status itself. The second one shouldn't be blocking and refers to the backup operation.
And yes. The backup operation state is SUCCESS, while the backup state might be PARTIAL (hence no full backup was made, there were errors).
So we have now an additional API that we query that then wraps the API of elasticsearch. With all these shiny scary workarounds like polling, since some APIs are blocking which might lead to a gateway timeout...
Gateway timeout? Yes. Since some operations can run a LONG (multiple hours) time and you don't want to have a ton of open connections hogging resources... You let the loadbalancer kill it. Most operations simply run in ES in the background, while the connection was killed.
So much joy and fun, isn't it?
Now add the latest SMR scandal and a few faulty (as in SMR instead of CMD) hdds in a hundred terabyte ZFS pool and you'll get my frustration level.
PS: The cluster has several dozen terabyte and a lot od nodes. If you have good advice, you're welcome - but please think carefully about this fact.
I might have accidentially vaporized people sending me links with solutions that don't work on large scale TM.2 -
I cannot believe that MS has not thought of something better than UAC... trying to re-install ADConnect after fixing an error, msi shits out 2502/2503 errors even though it worked first time on the original install. The fix, run the msi from an elevated cmd. Come On Microsoft!!!7

Mann i will always be a newbie to the world of linux, but running cmd on it, its always scary. Like one purge command and it went on deleting so many packages i didn't knew even existed at the first place.
I feel like a blind man following the blogs hoping to god that no wrong shit happens. And the blogs are also like "do step1 then step2 then step3, you will see x , do y and it will work" , and surprisingly it works!.
Linux is a beautiful mystery.
And why the hell is almost every browser in linux broken?
- Netflix, hotstsr and Spotify won't run on any versions of opera or chromium because opera didn't got some widevine installed.
- chrome runs but no good free vpn(i prefer hola/1click) works
- firefox is weirdly slow.
And yet this is the world's most lovable platform for web dev5 -
I am currently playing dumb with a potential hire and it's just so much fun I don't know if I should stop.
We gave the dev a little coding challenge to code a small expense tracking app. Nothing fancy, just to see how he well he could do on his own. We told him to take as much time as he requires.
He submitted it and I tried to run it. It worked alright but I could not register or login.
I debugged the issue with him for a while and told him I would look at it later since I am tied up with other tasks..
We are communicating via an IM.
Him: Or how did you run the project. I wish I was there to run it for you. Lol
Me: dotnet run. start without debugging
Him: From the cmd?
At this point I about to get pissed. Where else would I run 'dotnet run' from??
Me: I would hope so
Him: I always run it from the cmd. With administrative privileges
Me: Really?? Where can I find cmd?
Him: Yes. Do you use a Mac?
Me: nope. I am using windows2 -
Today a colleague of mine managed to run cmd as admin without credentials. He does not have admin privileges so normally he can't do that.
He refuses to tell us how he did it.
Any idea how to do this in windows 10?14
