Bash "factoring" (IDK the real term) is useful too: "chmod 775 file{1,2,3,4}" will turn the last part into "file1 file2 file3 file4". It's quicker for creating copies of files too, like "cp file{,.bak}" instead of "cp file file.bak".
@@MrRozburn Oh, nice. I didn't know about the range syntax. It works for characters, too. But it looks like it's limited to ASCII characters. Or to characters with single-byte encodings. Not sure which.
Another useful trick is the key bind “alt+.” to use the last argument for the previous commands. For example, let say the command “cat /etc/resolv.conf” and now you want to edit this same file. This can be done typing “vi” and pressing “alt+.” and /etc/resolv.conf autocompletes in screen. And pressing multiple times it woks like a UP arrow key but for last previous commands arguments.
In general, you can refer to the i-th argument of the previous command using '!!:i'. To get to the last, use $ (-1 won't work) E.g: '!-2:2' gets you the second argument from the command before the previous one

Cant forget the almighty "Ctrl + r" Reverse lookup is hands down one of the best things for quick history stuff. Can be dangerous if your too eager though lol
@@bonkgameing Not to worry, we all start somewhere. If you're quick to press return on what you think is the right command you could end up running a command you dont want.
Just a couple of thoughts about history in bash: I personally don't save my bash history because with so many terminals open I wouldn't know which terminal will save its history; I have the string "\!" in my prompt to display a command number so that I can find the number of a previous command easily when I want to use ! to re-run said command.
“pushd” and “popd” are some cool commands I found useful when I knew I needed to eventually return to a directory. pushd /path/to/directory will push that directory to the “stack” in the terminal, so you can navigate anywhere you want thereafter, and when you execute popd, it’ll return you to the same directory you pushed previously. There’s also the “script” command which records your input and output to a file of your choice which is useful when logging your actions in the terminal.
There is a bunches of nonsense shell plugins that essentially mimic the behavior of pushd and popd in a slightly different way and people cherish these plugins that use a million lines of shell scripting and slow down their shells as if pushd and popd do no exist.
@yuuwe pretty sure if you change default shell from ksh/csh/whatever the default shell is to something like bash or zsh you will get that functionality. Also you could probably alias something together in your default shell in whatever bsd to essentially do a pushd/popd.

I know about changing Bash to vi bindings, but Bash has Emacs bindings by default, even without Emacs installed. Also, vi support is available without Vim or some other vi installed. Both are features of libreadline. Check ldd `which bash` and you'll see libreadline, not anything from Vim or Emacs. Imagine you've switched your keyboard to Dvorak, and everyone else is still using QWERTY. That's what the situation with Bash is like. Even if you're committed to using vi bindings, it's worth knowing Emacs basics for when you inevitably encounter it in the wild as the default.
yeah some people like to bash on (lol) emacs bindings without having even used them. there's seldom a time you need to use vi when you already know emacs, but learning both for the sake of knowing them is obviously a good idea. this example of ssh-ing into a server with only vi installed never made much sense to me, because either you'd use vi on the local machine as a vim user or you'd tramp into the file remotely as an emacs user. (also, modal editing on the command line? ew...)
Top Tier Content. I think the only thing I ever really used was "sudo !!" in the whole video, and I've been using Linux in some degree since I was 14. I did know somewhat of the other history commands and shortcuts, and using VI on the CLI... but never have really applied it. Old habits die hard. I am pretty good with using readline shortcuts to quickly jump by word, etc.
Instead of the double bang, shift up and shift down. Let's you cycle through your shell history. Or just up and down depending on which terminal your using.
On Stackoverflow I found this advice that I cant live without anymore: In my home folder I create a file named .inputrc Inside goes this "\e[5~": history-search-backward "\e[6~": history-search-forward Then typing however much of a previous command I wish & using the page up/down buttons searches the history

I have such towering seniority that, by simply being able to use a command line at all, my colleagues are impressed to the point of fainting. Truly a god among men
I saw `sudo vim` in your history and just wanted to say that there is a command `sudoedit` specifically for that. It allows you to edit files with sudo rights but using your own user, not root
Ah, the vi mode is something I will try out. I do occasionally end up in situations where I start trying to use vi commands while in shell just to realise that I’m not in vim.
Substitution you can preform with ^ instead of !!:s/. So in your example you can just do ^status^start and that will replace the word start with status.
These shortcuts work in weird terminals as well: Ctrl-A: Jump to the start of the cmd line (like Home) Ctrl-E: Jump to the end of the line (like End) Ctrl-P: Jump to the last command (like up arrow) Ctrl-N: Jump to the next command (like down arrow) Ctrl-B: Move the cursor to the left (like left arrow) Ctrl-F: Move the cursor to the right (like right arrow) Ctrl-W: Delete the word to the left of the cursor Ctrl-S: suspend output (like scroll lock on in tty) Ctrl-Q: continue output (like turning scroll lock off in tty) Ctrl-L: clear the screen Did I miss anything?
Ctrl-H: delete last (backspace) Ctrl-U delete from current char to beginning of line Ctrl-D: delete next (delete key) Esc D: delete from current character to word break Ctrl-R: Search backwards (Ctrl-S is search forwards, but you have to disable suspend to use it)
These commands come from emacs, and as such you should also have: Ctrl-K: delete anything ahead of cursor Ctrl-Y: paste the last deleted thing (either with Ctrl-K or Ctrl-W) Alt-Y: If used right after a Ctrl-Y, cycles through the deleted sections
Best commands ever: - CTRL+w = clears word - CTRL + U = clears whole line There is nothing magical about unixy commands.. They are extemely powerful weapons you need to memorize.. There is logic to help you memorize such as `w` standing for word ..
@@crusaderACR yes. They're actually handled by a program called readline. You can configure readline to use vi key bindings. Also you could write your own shell or command line program and use readline as a library to get all the same functionality.
Nice vid. I would skip the advice though with regards to vi and just stick with the default bash keyboard shortcuts from the GNU Readline Library. These default shortcuts are used by many appliances and systems that you may encounter in your engineering career.

Can you get the row number of a history function using grep and then using it with ! Mark? This sounds like a good way to automatically one liner re run specific function by grep and can be added the changes
cat -n ~/.bash_history | grep mySearchPattern will show you the commands with your pattern and number lines, which you can then use with !. Or, if you like danger, you can automatically take the first match :P !$(cat -n ~/.bash_history | grep mySearchPattern | { read -a array ; echo ${array[0]} ; })
2:13 If I use my shell's vim bindings, I can edit the previous command in many less keystrokes than typing that. Still, I don't use bash so I don't have the double exclamation mark either way
I never got the hang of VI mode in bash and tend to stick with Emacs mode which I find much more intuitive. On the other hand I find Emacs too complicated for my needs and stick to VI.
i doubt you will see this but ide like to say thanks for getting linux out there a bit more ive just compiled dolphin from source today ( it was a fucking nightmare) and am currently using unbuntu now. while i have many issues now im ironing them out. the only come out when im using the terminal and are surprisingly easy to fix. no way in hell im trying gentoo anytime soon, fuck compiling from source. i have to say linux runs wonderfully on my little shit box.
If it's a range of something he could also use {1..9} or [1-9]. One thing I've found quite useful is when you want to match on 2 or more characters too, such as ls -d [Aa]?* to list everything that starts with an A or a but not merely a or A on their own. I have multiple folders that are sorted alphabetically.
I saw that you had two GPUs when you did neofetch, but they're different GPUs. Is that for GPU passthrough for gaming (or doing other GPU intensive tasks) on a KVM?
!$ should be mentioned too, it's expand your last word of previous command, it's handy when your last command is a file name or directory, then you can do cd !$ or vi !$. great video as always
Emacs does not need to be installed on the server, you can use it on the client and connect via ssh to the server directly from there (not the usual terminal emulator), and safely use your configuration of emacs
history | grep filters history by that word, also history has a number bedside each command, you can !n where n is the number to run the command, also I disagree on cli being superior, I do a lot of work with aws and its way easier on the gui, 1 click is like 3 commands sometimes
Vim is crucial to know, sometimes you don't have any other option, say you connect to a ssh server or a kubernetes pod that has minimal installation and you dont have permission to use apt. I use vim extension to vscode ( because sometimes you just need to use an IDE).
The exclamation mark commmand is a trap... professional programmers already understand why mutating states is bad idea. That's why functional programming is safer.
Hmm. Unconvinced about !-3* - unless there's an in-line expansion you can see and verify before running it. Also, use ? to match a single character or {...} to specify the endings. Or up-arrow to see the parameters and edit the start of the line.
another really helpful one is repeating the last command start with an 'f' for example, would be " !f " so if you remember the first letter(s), you can do multiple commands from history really quickly e.g. !bison !flex !gcc or !b !f !g
That is because CTRL-R is a default GNU Readline Library shortcut. He advocates using vi mode. So you probably have to tediously switch out of vi insert mode by pressing ESC followed by a sequence of other keys in order to achieve the same.
Honestly way more useful would be SSH tricks. Configuring it to use jumphost for certain Networks, using your ssh user by default, setting custom Ports for certain Servers, etc. Also interesting for new users might be common grep commands and for loops in the shell.

Shame you didn't mention the Ctrl+R trick!
That is because CTRL-R is a default GNU Readline Library shortcut. He advocates using vi mode. So you probably have to tediously switch out of vi insert mode by pressing ESC followed by a sequence of other keys in order to achieve the same.
Honestly way more useful would be SSH tricks. Configuring it to use jumphost for certain Networks, using your ssh user by default, setting custom Ports for certain Servers, etc. Also interesting for new users might be common grep commands and for loops in the shell.
I am kinda interested in getting there, but I don't feel comfortable with going there. so much to strive for.
Thanks👍
Useful tool: github.com/nvbn/thefuck
Cool shell written in Python with Python syntax and shell support: xon.sh/
What really made me look cool was to use CTRL+L instead of clean 😎
damn boy got the threadripper just to drive arch
Protip: Use Ctrl+R in combination with the fzf program for a much better command search experience
I use ctrl+r all the time, never heard of fzf, looking into it now. What's awesome about it?
