Don't forget the lovely functionality of hitting the TAB key while cd'ing around.. saves alot of typing

I've been using Linux since 2002 and I didn't know about "-". Yay learning! Linux is awesome, and so are you.

I missed the "...and so are you!" Part at the end😢❤ great vid. Always comforting to watch one of these

Not related specifically to `cd`, but using Alt-. (hold alt, tap period) is fantastic when navigating the shell. If I've just done `mkdir -p /some/long/path/name`, I can then go to the newly created directory by typing `cd ` , pressing Alt-. to insert the last word of the last command, and then enter. If it's from several commands ago, I just keep pressing Alt-. Then there's also `pushd .` and `popd` if you wanna get fancy.

Alt-. does not seem to work in vi mode. After some googling I found that adding the following to ~/.inputrc will do it: set editing-mode vi set keymap vi-insert "\e.":yank-last-arg Those who do not have a ~/.inputrc can just create it. Up to now I simply used !$ but Alt-. has the advantage of going back in history when pressed repeatedly.

Huh. Interesting. I come from a Windows background but have absolutely loved PowerShell. The more I learn about UNIX shells and commands, the more I see the roots of what I'm more familiar with. I want to be better on Linux, so I'll keep learning to do it the Linux way !

when I saw this video was published, I thought, "I'll bet I manage to learn something new". And I did. Never knew about "cd -". Awesome!

Was thinking.. oh cute the 'cd' command. I will watch for fun. And then BAM! Veronica hits me with the cd - It's been something like 42 years and I did not know (remember) that. Thank you!

Your videos have a @Technology Connections vibe. So comforting to watch.

One of the things that I both love and hate about Linux is that even though I've been using it for years, I still learn new things about even basic stuff all the time. I love that there's all that depth, but hate that it's all kind of secret knowledge. The only tip I would add to this, btw, is how helpful tab autocomplete can be when using CD. For example, if you were in ~/Downloads/songs/RockyHorror and wanted to get to Absolute Treasures but couldn't quite remember how to escape spaces, you could always type "cd Abs" and then the tab key and it'll complete all the escaping for you. Sure it's lazy, but it's also very very safe.

I totally never knew about man builtins, and I've been using this stuff for decades!

It's a good one!! :)

Just a quick comment on the question raised at the end of why cd is a shell built-in. It's a function of the chdir system call. That system call changes the working directory of the process that calls it. But when running an external program, the shell forks a child process. So a chdir call made there would only change the working directory of the child, not of the shell process itself. As a result you can't really have an application program that changes the working directory of the interactive user, short of starting a new shell and killing the parent process. Another interesting tidbit is that the behavior of things like '-' and the '~' notation are actually implement in the shell, and not the kernel. I.e., you can't expect them to work if you write a program that calls chdir to change the directory the program is running in. On the other hand '..' is implemented in the OS and in most file system implementations is literally stored in the directory data structures on the disk. (Okay, that wasn't as quick as I intended.)

here's a thing I tripped over in my early linux days: there has to be a space between "cd" and ".." unlike in DOS, where it works without the space. this may not be a common problem anymore though :)

I'm just happy to hear someone else pronounce sudo like "pseudo" or "judo". All jokes aside, I like the Lil Linux Lesson series, very informative.

"cd" is one of those very important commands in the shell. Plus it allows me to go places in my computer and sometimes I can go on an adventure in my system. OK I know I'm a nerd.

OK I've been using Unix since the early 90s, I watched this just for fun expecting to learn nothing cause it's like the a-b-c's, and damned if I didn't actually learn something! I never knew about "cd -"! Nice!

I actually learned multiple things new to me here, thank you! :)

Good video. Using aliases you can go to your most used folders typing a single world like "Downloads". I created aliases for all my most used folders so I can move between them really fast.

I didn't know the thing about spaces in folder names, I've been confused by that before so I'm glad to know what was happening. I try to avoid the terminal if possible as I'm not as comfortable using it so these videos are really helpful for when I need to use it.

This is such based Linux content! Glad to discover more content creators that seem inclusive and passionate about the subject! 🎉

Good video. CD is familiar to me because of the similarity to the DOS CD command, and I was quite a DOS wizard many years ago. My big stumbling block has been learning to navigate through different drives, given that Linux treats every thing as one big directory structure. There's always more to learn...

Thanks Veronica. A lot of the CLI commands like this make sense for me (as DOS 6.22 was my first operating system and all of them made sense) because their initials actually stand for what they do (CD, Change Directory, MkDir (or MD) Make Directory, etc,) but what about some of the commands that don't do this like (PWD, which I thought was for password, but, no, and the Touch command, not a clue.) I hope that you carry on with this series. Thanks Veronica.

You can configure some shells so they treat entering a directory name as an implicit cd to that directory: bash: shopt -s autocd zsh: setopt autocd tcsh: set implicitcd fish: default, but requires a trailing / or leading / or ./ nushell: default, but requires a leading / or ./

You rock, Veronica! Love the Amiga Workbench screenshot. I am horrified to admit that as a UNIX user off and on since about 1990, I only learned about cd - about a year ago. I never liked using pushd/popd, they seemed a little too clunky for me.

I love the shirt! Ethernet twisted pair? :D

I am a windows user and I would like to start using the linux subsystem. Considering this channel talks about a varied number of distributions of linux, I would like to suggest making about about wsl. For example, I still don't know if it is fully compatible with a standalone installation of linux, or if it performs better or worse... It would be interesting to have a video on that. But I do understand that viewers might not want to know about windows hehe

In Bash, to get help about each builtin, use the "help" builtin: e.g. `help cd`. This is something Z shell overlooks. In general, I find zsh man pages divided in an unintuitive way, as opposed to bash's single page that you can easily `/`-search through.

I didn't know about cd -. I don't do a whole lot of navigation on the bash prompt, though. I prefer using vifm for directory and file navigation. Once you're there, it's easy to open a shell if you want.

hi there, nice vid, i like: alias ..='cd ..' yay

I tend to go with either one. I also go with "drawer" from Amiga stuff, so my mind is pretty flexible on it. If I think about it, I imagine I call it "directory" more from the terminal and "folder" more from a GUI.

Thank you for the series Lil' Linux Lesson! Quick question about the BASH-BUILTINS(7) what the (7) for IP(8) has (8) any help explaining it would be most helpful.

Fun little fact, the dot is used as a symbol for the current directory by the cd command. Also when you specify an absolute path, the cd command starts at the root of your files system, then it switches to relative mod, then it starts reading the path directory by directory, you can see that by trying something like cd /home/user/Pictures/../Desktop/RandomDirectoryOnMyDesktop which is equivalent to run cd /home/user/Desktop/RandomDirectoryOnMyDesktop

About the /usr/bin/cd file, I would guess that is is to support the use of other shells that don't have cd builtin, without the need to make (and maintain) a separate binary for the command.

cd ~ cd `pwd -P` Are useful additions

Seems like I've skipped a few docs because after a decade with Linux I learnt today 'cd -' -command.

You can use `help cd` rather than man built-ins and scrolling. The built-ins have entries under `help`

Was waiting for `cd -` to yell "I KNEW THAAAT!!" but I didn't know why it worked. I also use cd without args to get to home a lot these days since getting a tilde and then pressing Enter is rather uncomfortable on a de_DE keyboard.

to correct you ed is actually a UNIX program that came from the Official UNIX system nd its not on Linux as that is a kernel its on GNU.

Not everyone knows what you know. I'm making things at multiple skill levels.

For bash builtins, the help command is a bit more sensible than the manpage I never knew I could find (at least under Debian, don't know in RedHat world) help cd

Single dot refers to the current directory (which is usually 100% redundant when using cd) and double dot means one directory up. I think it's sad that the pattern doesn't continue. Triple dot for two levels up, and so on.

Nice! I always just type the two dots '..' to go up a directory, instead of 'cd ..' I'm not sure if this works everywhere, as I am using zsh as my shell.

@mulad

"cd.." (no space) could definitely be set up as an alias if you wanted, and I imagine ".." is a default alias on some distros. I imagine the "cd ..." (3 dots) in zsh was done for people who remembered using that trick in DOS/Windows. In the broadest case, "cd .." works because there is literally a directory named ".." in most paths, which you can see with "ls -l", but "..." (3 dots) isn't really there. There isn't a ".." directory in the root (/) directory, so some shells or programs could throw an error if you tried to go up a directory from that path

There is no manual entry for builtins on Void Linux.

I've a question that you could even do a video about :D What company will be the first to make an AI operating system? Do you think it will just be a regular OS with AI capability or a completely new kind of OS that runs off the back of an AI? What would it even look like or be like??

TIL cd - and cd

After watching almost all videos I have a recommendation. Can you leave important text a little bit longer on screen. I almost can never read everything and have to rewind the video. For jokes gags and other kind of potentially vimy humor it's OK obviously. 😊

The cd command is also very useful with combining them with other shell commands, such as 'ls [directory] -al' to view all hidden files and the permissions assigned to them, such as 'cd /bin && ls -al', where the '&&' operator allows a second command specified right after the first. One way to familiarise with all the built-in shell commands and individual app commands, is through installing Arch Linux, Gentoo, Void Linux or some distribution in where you can manually install the OS.

@theherk

`;` allows a following command in most shells, where `&&` is a condition that will only execute the next command if those preceding return 0. Using this in the case of combining `cd` with `ls` is actually more keystrokes than just using the return key. But other examples work well for combination with `cd` like `find … -exec cd {}; … && cd -`.
