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.

"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.

@@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.

VERY useful tips here, I plan to start using them regularly. You’re proving to be my most useful resource on YT in my Linux journey. Also enjoying your sysadmin series.

Huge Thanks for the 2 shell videos you've made. Been using CLI over a decade but did not know any of these tricks and have always found it slow and clunky when compared to the gui. Well no more, not after these massive quality of life improvements... Been 6 months since I watched these videos but I still think of you and smile the endless times a day I use these tricks!

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

11 minutes later and I don't know how I survived without these tricks for so long. Great stuff man

Thank you so much Dave for sharing your knowledge, looking forward for future videos. Keep it up mate!

If you ever need to purposefully mess up a terminal like for 9:47, I've found the command "sleep 1 | vim" will do that consistently on any terminal.

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.

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.

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.

My recommendation for vim users: add ```set -o vi``` (or something like that, too lazy to look it up) to your bashrc, and use your favorite vi-keybindings in your shell (press esc to get into normal mode)

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

Thank you!!! This video should never die!

first useful shell video tutorial I ever ran into

very informative, i often use for example "ssh " to repeat the last ssh ... command

I remember a while back you saying your co workers would give you a hard time about using advanced commands... I can see why , I have watched a lot of tutorials , some of the things you do I haven't seen ANYWHERE else. I like this channel because even if I go way back in your history everything is still relevant and useful. 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.

wow this is just wonderful, especially the reset command for me cos lately I have been using a remote shell and it usually gets weird after a while, but I tend to just manage...so this definitely works and I will be using it from now on, thanks!

Great video! What I use probably the most is Ctrl+r to quickly search the command history. By using Ctrl+r you can go to the next hit and with Ctrl+R to the previous.

I actually found the --curses tangent to be useful. I have cursed ubuntu myself when it popped up in a gui. Great tips keep up the good work.

Great idea with the less +F , I prefer using regular old less then pressing shift+G, it takes you to the bottom of the file and you can scroll up without gluing.

Perfect tricks. thank you so much!

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.

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^"

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

Thanks a lot for these tricks.

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.
