I'm in love with your videos and Linux series. This is the best possible way to explain how this sucker works! Please make a video about Linux machine common troubleshooting. Like check what's happening with cpu/ram/memory, how to see what's wrong with database on a server or website if it's hosted on a linux machine.

[@papakeks]

Another simple way to create nested directories is with ranges. For example: mkdir -p \ shelf{0..9}/book{0..9}/page{0..9}/letter{0..9} Then you get a path like this shelf0/book1/page2/letter3/ And about 10000 directories 😉

[@KCrouch-t2o]

library of babel?

[@andreasklindt7144]

This is also a good example why scripting or learning cli commands should always be done in bash. Because when I enter your command in fish I get this: └── shelf{0..9} └── book{0..9} └── page{0..9} └── letter{0..9} 4 directories, 0 files My advise to new linux users: Don't use fancy terminals like fish when you learn basic commands. Stay in bash for that.

[@jcbenge08]

Glad you're back, Chuck! Hope your time off was relaxing, we don't want you to burn out!

[@jasonbaldini]

I think you should add at the beginning for beginners to type alias and find out if there are any default aliases setup for commands you’re using, because it’s normal or has been normal that they are setup.

[@seigfredvincentcagoco]

Thanks, chuck! I just finished all your Linux for Hackers playlists.

If you are back up files with cp command, use -p option to preserve time related metadata. It's really useful to see when it has actually modified last time, and not the time when it's been backed up.

And all the directories contain the "Aughhhhhh" sound💀💀

[@tensionspan]

Try these for multiple directory and file creations: mkdir dirs{0001..9999} touch files{0001..9999} BTW in bash it's called "Brace expansion" and can some funky stuff with it. Look it up!

[@bobpond6381]

Great content as always. Before Linus existed and when databases were prohibitively expensive I wrote a complete job control system in the first port of AT&T Unix to i386 using directory names as primary keys and the best we had at the time for forms on terminals. The file system was a pretty good database. We used that thing for years.

[@dinohunter7176]

Fun fact: windows calls them folders, but in cmd is using mkdir as well to create folders

[@v01d_r34l1ty]

It's more of a DE/CLI difference. When in a DE, most operating systems are going to refer to directories as "Folders." When in their respective CLI, they will be referred to as "Directories." (Edit: for clarification, DE stands for Desktop Environment and CLI stands for Command-Line Interface)

[@rdx8122]

first video of NetworkChuck where i really learnt something (actually only something, but still something ), nice tutorial

[@williamo1938]

You may think from Chucks joking, but this is a truly an eye opening learning experience. It proves that ms is just a data miner, not a software developer. This is how you show the true capabilities of good programming; by maxing things out to the limit, showing us how much are machines are truly capable of.

[@DarkGT]

You can change the color pallet of the terminal to match your visibility ability.

[@IntenseGrid]

Directory vs Folder, unix and dos predate Windows with directory as both of them go way back and have the mkdir command. I think "Folder" might have originated with the Mac. AmigaDOS and GUI had an even worse "Drawers". Can't we all just go with an already set standard terminology of "directory"???

[@falxonPSN]

I think you are correct that Macintosh was the first to use "folder" syntax which was then adopted by Windows 3.x. I can't remember what Windows 1.0 and 2.0 had but I want to say they still used "directories."

[@sir6693]

Not only he creates cool directories but he's also cool at teaching. Thank you for the amazing stuff you teach!

[@zapityzapzap]

It's totally Windows that renamed directories to folders. Don't believe me? Remember MS-DOS? MKDIR, DIR, RMDIR, etc?

[@anilkumarhansda8087]

Wait I never thought about it that way ... I just typed mkdir like I do in Linux and moved on

[@Shirtysneez]

@tradde11 Actually there's a historical reason why Microsoft used "\". The first MS-DOS versions did not yet support directories. But "/" was already used by IBM as a "switch'" to run a program with an option to change the behavior of the program. For example: a sorting program might list names from a-z but using a switch the program reversed the order of the list. The word "switch" dates back to an actual switch on a computer in the 70ies. An operator (a real person) could load a program and (optionally) flip a switch to change the behavior of that program. Back then computers did not have computer screens. Everything was outputted to a printer. Most of the physical actions (like flipping a switch, loading a program) were done by a person: the operator. But soon lot of these physical actions were taken over by software: the 'operating system'. (the operator was replaced by the operating system) So when MS-DOS finally supported directories they could not use "/" as that was already being used as a program switch. So they chose "\".

[@nathanlaird]

@@Shirtysneez Yes, it's IBM's fault. They could have just used "-" to pass parameters if they had been interested in being compatible with the Unix world.

[@Sockcatgoldpuppet]

​@tradde11it's fucking disgusting and they can't keep getting away with it

[@paulistastars]

windows also call Directories es in Unix, people started to call it folders after windows got a GUI

THANK YOU again

[@austinmorganmakesmusic]

Nice video. You could run: mkdir dir{1..1000000} and that would also do it. You could then run top and or htop in another window/terminal to watch how that effects the machine.

13:22 pretty sure DJ Khaleds directory looks like this

[@circadianrebel]

They are technically called "directories" in windows too. The use of "folder" in a colloquial term that showed up after GUIs became common, as an easier to understand concept for people that are less tech literate. The two can mostly be used interchangeably. In both windows and linux almost everything API or CLI uses "directory" and user facing GUI will use the word "folder" when needed.

[@shashanksinghgautam]

Really Enjoyed this video 😂👌

[@gmc9753]

8:25 Actually, you can just use the command "mv file.txt coolstuff". If there is an existing directory called coolstuff in the current directory, the file will be put into that directory. If coolstuff doesn't exist, the file will be renamed to coolstuff in the current directory.

[@Chamaeleo]

I just want to say sudo thank you to you! That was a great course, exactly what I needed :)

[@petermergenthaler604]

Bro I love your videos!!! You missed out a directory/anotherone/bites/the/dust joke hehe

[@James-li8cm]

directory became "folder" when windows 95 first came out (in the dos days it was directory) that is when they came out with the windows file explorer which displayed directories as folders... although apple did this same thing WAY BEFORE Microsoft ever did remember dos command to list contents of a "directory" is "dir" (dirp, dirp) but in the linux world which has always been command line first (insert political statement here), it has always been "directory"

[@donaldmickunas8552]

Folders is a gui related term while Directory is a tty/command line related term. They mean the same thing from different perspectives.

[@gregf9160]

A million directories on a Linux filesystem is irrelevant. Depends on the actual file system, but _any_ genuine UNIX or Linux FS wouldn't care. However, utilities like tree, and probably ls, will simply not work ... for example: ext4 does not limit the number of subdirectories in a single directory, except by the inherent size limit of the directory itself. (In ext3 a directory can have at most 32,000 subdirectories.) To allow for larger directories and continued performance, ext4 in Linux 2.6.23 and later turns on HTree indices (a specialized version of a B-tree) by default, which allows directories up to approximately 10-12 million entries to be stored in the 2-level HTree index and 2 GB directory size limit for 4 KiB block size, depending on the filename length. In Linux 4.12 and later the _largedir_ feature enabled a 3-level HTree and directory sizes over 2 GB, allowing approximately 6 billion entries in a single directory.

[@jonakers704]

Having seen directories with hundreds of thousands of files in them (no... really... God I had biologists sometimes) this is both a blessing and a curse. A blessing because when those people created all of those little files (seriously, why do you need thousands upon thousands of little 4k files?) it did not crash the system, but also a curse because it let them create that many in the first place without saying "Nope... sorry... you have reached your limit... learn how to program better so that you aren't using the filesystem like a database!"

[@jonathanbuzzard1376]

@@jonakers704 Argh the curse of the bioinfomatics people. I have seen that myself. What we do to "avoid" the problem on our HPC system in the first place is put a quota on the number of files they can have. I think we are at about 100 millions files on the file system now, but no individual user can have more than one million. Actually the hard quota is two million, with a 30 day grace period, but the soft quota is one million. Actually they can but they firstly have to ask and secondly there is a charge. Only a handful of people have ever asked and nobody has gone ahead when the issue of the cost was raised. Prior to the introduction of quotas on files we had one user with 17 million files. We are using GPFS and with the right setup a search of one billion files will take under an hour, ~15 minutes springs to mind.

[@jonakers704]

@@jonathanbuzzard1376 We are using lustre for our HPC system, sitting on around seven PB of storage. Users have to purchase their storage allotment on the system, so they get to do with it as they wish. We have had to take an "education of the user" approach for huge numbers of files in order to combat the problem, as we are not able to utilize quotas on the number of files due to our favorite 8th OSI layer... politics.

[@jonathanbuzzard6648]

@@jonakers704 well thankfully we are no longer using the pit of some that is Lustre and are on GPFS, but that is a different story. However the point is that in addition to cost for capacity, every file has a cost too. So a single file 1MB in size is cheaper to store than a thousand files 1KB in size. You are burning through those expensive flash disks for metadata rather than cheap large capacity spinners. You are also filling up the TSM database which is also on expensive flash. All we do is put a reasonable default limit on both capacity and number of files. Above this you have to pay and I have this costed out for both capacity and files. If a user wants to store 10 million files that is absolutely possible they just have to pay the full economic cost of doing so, and they baulk at the cost in my experience. Basically it means they have to have a discussion with use *before* they store millions of files which gives us the opportunity to educate them.
