[@whiskeytuesday]

Instead of you can also just use !$ the same way you used !! in the first tip. There's actually a lot of notation for this which is terminal agnostic and supported in zsh as well as bash and probably others. For instance !-2 gives you the command before last, !-3 the one before that etc. $ on the end gives you the last argument of that command. !^ gives you the first argument, !:2 or !* gives the second argument. All of these things can be combined too, for instance !-3:2-$, which gives the second to last argument of the third-last command or !-3:2-3 which gives the second and third arguments to the third last command. Hard to keep straight at first but a very powerful way of getting around once you jam it into your head.

[@jplflyer]

I've been programming professionally for 40 years, most of that in the Linux world, and it's amazing the learning process never ends.

[@JerryPenna]

Yeah, I’ve used less a ton but not with other flags. I tried less +F but didn’t work.

[@allen_joji]

Do you still love programming ?

[@jplflyer]

@@allen_joji Yeah, I do. I'll eventually retire, but it's unlikely I'll ever stop programming. I'll do my own projects is all. My opinion about careers: you should find something you can be passionate about, that you want to do even if you weren't being paid. We spent far too much of our lives at our jobs, and do you want it to be soul-sucking? The last people I want to work with: the ones who see it as a job. They're only there for the paycheck. Yeah, if I won the lottery, I'd quit the day job. But I'd still program. I'd just get to pick what I work on.

Another nice trick worth mentioning is reverse search (Ctrl + r), where you can type a part of your command and it'll bring on the last command entered with the expression in it. You can see older/newer commands by pressing Ctrl+r and Ctrl+R respectively. It's a bit more common so maybe not really a trick, but still some people might not know about it.

"Alt + backspace" is more useful than "ctrl + w" in my oppinion. While the latter only stops at whitespaces, the former also stops at special characters, e.g. slashes, so you can edit your way to parent directories much faster.

Both are useful but for different cases. Clear entire arg or go word by word. Personally I use both depending on the case.

[@josephknightcom]

thanks

[@frydac]

try fzf, it makes ctrl-r a dropdown list (i think it opens a tmux pane on the fly iirc) and lets you search in a fuzzy manner. And also search for files like that, I can't live without it anymore..

I remember a while back you saying your co workers would give you a hard time about using advanced commands...

I've been subscribed but I forgot to hit the bell icon , so I didn't even know you were back. Glad to hear it though.

[@AleksandarBosakov]

Holy cow, it's been 12 years since the last time I used Windows on my home PC, and I do use the CLI a lot, yet I didn't know some of those tricks. Great work!

[@AndrewDeFaria]

Good video. I learned a couple of new tricks! One trick I knew already and always use is the Alt- thing. I describe it to others this way - Alt- brings up the last "word" of the previous command. Think of it as an object. So you do ls /tmp/file. Now /tmp/file is the object. Want to know more about the object? Type ls -l Alt-. Contents? - more (or less) Alt-. File's junk - rm Alt-. But what's more is say you have this in your history: 501 touch /tmp/file 502 ls /tmp/file 503 echo file? 504 uname -a 505 history Typing Alt- at the command prompt will bring forth "history". But typing another Alt- will bring up "-a". Another one and you get "file?". One more and you get "/tmp/file". So if you want that Alt- object because it was say a filename object but it was not the last word of the immediately preceding command then keep hitting Alt- until you get back that file object.

[@locusinbloom]

I was expecting to be disappointed (didn't notice who published it before I clicked watch, lol) but I didn't know a single one of these, thank you! All of your videos are great.

[@TheDave000]

How did I not know about less +F? This literally changes everything in my job!

[@nonconsensualopinion]

Maybe it's overkill, but I always just use vim. It loads very quickly and gives me the ability to search all around any log, jump to the bottom, etc. vim logfile, shift-g to get to bottom, :q to exit. Done.

[@SJmurov]

@@nonconsensualopinion But does it follow?

[@EdselAdap]

Great video! I consider myself a seasoned shell user since I've been doing this stuff for 30+ years but you've taught me some new stuff. Two things to add though to fix a borked terminal is "stty sane" and "echo ctrl-v ctrl-o". Excellent tutorial!

[@KirtFitzpatrick]

Great tips, thanks for sharing! I'm proud that I knew a couple already but most are new to me. I'm going to incorporate these into my day to day for sure. The comment section is gold too.

[@tildessmoo]

Quick note on the keyboard shortcuts: These are default Bash terminal commands, which are based on Emacs commands; however, you can also add "set -o vi" to your .bashrc to set Vi mode, and then you can use Vi shortcuts instead. Since one of the big things that keeps Vi[m] competitive with Emacs is the power of its navigation commands, this can make you even more efficient, though the learning curve is pretty severe if you're not already used to navigating in Vi, so obviously this is only something to do if it's already your preferred editor.

[@IRgEEK]

Thanks for the video. Although I am using GNU/Linux for more than 15 years, I forgot about !! and I didn't know about C-x-e. Thanks.

[@donaldwebster2866]

If your terminal is really borked, you may need to use Ctr-J (before and after reset) instead of as in: reset. Also, G and 1G in less are super useful, being go to the end or beginning of a file. I like Alt-. I might start using that instead of !$ The other bang command is ! which is insert the last command that starts with . In you one example, if find wasn't the previous command, you could have run "sudo !find" or what I do many times is "!le" to run my last less command; likewise "!ls"

[@AjitV]

BONUS tip was the best. I have the issue all the time especially after using gdb ... Thank you sir, U've earned a Subscriber

[@Colony28]

Thanks for the tips! When I saw the alt+f/b, I realized how annoying it is without it. About less +F, it's great for one logfile, but I can do tail multiple logs with tail, which is sometimes useful: tail -f /var/log/something/*.log

[@ryanbard3560]

Fyi, another nice thing about using less over tail is that you can put in some search terms before kicking on the live tail mode and they'll be highlighted. Ex. put in a /error|warning|critical then hit shift+F and as things scroll by, error, warning, and critical will be highlighted.

[@beeeeep]

You can even use & interested of / to filter what you like to see.

[@ALTracer]

| ccze --mode ansi also does that

[@KirtFitzpatrick]

I wonder if there is a way to get automatic highlighting like with bat.

[@RedStefan]

Sudo!! I hit the ground Sudo!! That awful sound Sudo!! My baby shot me down

[@zerbitx]

The ctrl-x-e trick is great for small modifications to commands from your history as well. You can up arrow, or bang or history | grep or whatever to a previous long gnarly command, then hit ctrl-x-e to make easier surgical modifications to it.

[@lawrencedoliveiro9104]

4:51 A few further tips with less: * I like to add the -i and -X options. -X stops it clearing the screen when it exits, and -i means searches are case-insensitive. In fact, I like to have the alias “more='less -iX'” defined, since I don’t see the point in the standard “more” command. * The +F option corresponds to pressing F while already in less. This is true of all the options beginning “+”: they correspond to keystrokes you type within a less display. Another useful one is +G, to start viewing the file from its current end.

[@sarundayo]

Just came across this channel and I love it! Thanks for showing us how wonderful Linux can be and how to use it.

[@kleetus88]

as an adjunct to !!, I find I use !$ A LOT. This handy thing refers to the last argument on the last command. e.g. mkdir -p /home, then cd !$. This will be equiv to cd /home.

less -n helps a TON on large files (doesn't count line numbers). -S can be useful in logs as well (no wrap)

[@codeman99-dev]

I almost always use `less -FRS` -F will "quit if one screen" or "there is no need for scrolling" -R will allow correct width calculation of control characters. Especially useful if you are piping a command and still want the color output.

[@Albertux]

One thing to mention, keyboard shortcuts are using emacs key bindings bash, you can run "set -o vi" to have vi key bindings

[@tutoriaLinux]

Yep, I mention that in the basics tutorial linked at the beginning of the video -- but it's useful to have here as well. Thanks!

[@davidmaxwaterman]

Yeah, it seems really odd to see him use Emacs on the command line but then use vi for editing. Better to be consistent one way or the other, imo.

[@bloodgain]

Well, it's not technically emacs bindings, but readline bindings, which were based on emacs since it was written first. Since it's so ubiquitous in GNU shell apps, it's a good idea to be relatively familiar with it, no matter what your favorite editor is. Using it every day in your shell is a good way to remain familiar. It also means you can walk up to an unconfigured shell (e.g. someone else's) and function normally. Plus, modal editing makes a lot of sense for a file, but less so for your command line, until you need to edit a complicated multi-line command. So I leave my bash settings at the readline default, and just fire up Vim with Ctrl-x,e when I need it -- best of both worlds.

[@thomasmarshall4472]

bloodgain , I just love that people seem to be re-"discovering" vi{m} again for text editing. Keeping your hands on the primary keys is SUCH a win over getting emacs-pinky and/or lifting your hand up to jump to the arrow keys. Been using it since the 80's, and if only the "vi-like" plugins for IntelliJ and Netbeans worked as well.

[@bloodgain]

Thomas Marshall The Vim plugin for IDEA-based editors like IntelliJ is pretty decent, but I agree that in general they leave a lot to be desired over native Vim. I'd much rather see Vim integrated as an editor. That's not too difficult with emacs, but it's much harder with Vim. I think Neovim is trying to address that; let's hope they succeed! Anecdotally, I find that the kind of people who are lifelong learners tend to take quickly to Vim once they get a taste of modal editing. I'm helping a PhD engineer learn it at work now, and he mostly writes Matlab for us (though he's falling in love with Python, as you might expect).

[@aemonge88]

This works for a chosen default input method. Bash auto set the option "set -o emacs", so you can move in the line like you would move in emacs. For VIM input method like you can set it to vi "set -o vi", then you can move vi style. Important to remap you esc key to some key which is more near to your fingers ( like blocCaps ), since vi heavelly relays on the esc key to switch from and to visual and insert modes

[@osquigene]

For tip 5 you can just do "mtr !$" (last argument) or "mtr !*" (all arguments) which both have the advantage of not being terminal dependent (just relies on history). I think even without history "mtr $_" would work. Or you can even have a bit of fun "^ping^mtr^"

[@osquigene]

Yes, if you want the detail of that you can refer to 9.3.1 and 9.3.3 in bash manual. You can do stuff like, creating a file: touch A/B/C/d.txt then moving to the directory: cd !$:h # h: Remove a trailing pathname component, leaving only the head. You'll also see: ^string1^string2^ Quick Substitution. Repeat the last command, replacing string1 with string2. Equivalent to !!:s/string1/string2/. Similar things exists for parameter substitution (which I personally only use for file names/paths manipulation): www.gnu.org/software/bash/manual/bashref.html#Shell-Parameter-Expansion www.tldp.org/LDP/abs/html/parameter-substitution.html You have an example in the documentation that shows how this can be used: www.gnu.org/software/bash/manual/bashref.html#A-Programmable-Completion-Example

One note, it needs to be after a newline, if it doesn't work try pressing enter first. Also if you're connected to another host over ssh and you're using tmux and connecting to other hosts (like two ssh jumps), you can still use this trick to kill the remote ssh sessions by using tmux send-keys. `ctrl+b :` and then at the tmux prompt type `send-keys "~."`

less will also re-load a file when you press "end" on the keyboard so you can follow at your own pace and not have stuff scrolling by that you can't even keep up.

Heads up, ctrl+W uses spaces to delimit words only if your $IFS is equal to [SPACE]. It's the variable (bash) uses to determine what separates bash keywords

[@EbonySeraphim]

If you're a capable vim user you should do the following: 1. set -o vi # in your shell (not sure what it is outside of bash) 2. Remap your CAPS LOCK key to CTRL. 3. Understand that you can get to normal mode in your shell by pressing CTRL+[ instead of ESC so you don't have to lift your hand to get there or stretch your left pinky. There ya go. Fast access to command history, with vim motions to edit your command input. Pretty much erases the need to jump into my editor to manage a command.

ctrl+x+e That was a *really* nice trick. I didn't know about that one! I think it would also be very useful when you're testing things. At least that's my workflow - I'll write my program, but need to test a specific command or something. I then go to just a shell and experiment. I could write a temporary script that does this, but to drop into a temporary file like that, directly from the shell, is probably much nicer.

I did not know less' +F option. Thanks a bunch, I'm sure that'll come in handy.

ctrl-k, ctrl-u, ctrl-w, ctrl-y Game changers for me. Thanks!

less -n tells less to not count lines, makes +F quick on large files. less -j20 tells less to highlight search results 20 lines below the top, gives you context for the results. My default less invocation is less -nj20, never hurts.

These videos are great! Looking forward to more and more in-depth practical and theory based tutorials.

Yeah, I've got some advanced ones coming -- in-depth systemd tutorials, compiling a kernel, writing your own syscalls. Woohoo!
