^p and ^n for previous and next line, ^w to kill last word, ^y to yank last word (yes, cut and paste work in the terminal, without the mouse, but don't share the mouse kill buffer).
ctrl u to delete the whole line, ctrl t to switch places of the 2 last letters behind the cursor, ctrl shift c/v to copy and paste in the terminal; obv there are more shortcuts. also you can write to a file without opening it using "echo banana > file.txt" the > symbol will delete all in the file and write what you want, you can append with >>. you can use the output of a command as a command itself by entering the command in "$(command)" and you can redirect standard output in standard input with the | symbol (e.g find banana | grep something). these are just some useful tricks to do stuff in a faster way
Good tips for beginners! Maybe add: - locate / find to search for files - rsync for nice backups / more comfortable way to copy files - du -m | sort -n or baobab to see what takes up how much space on the disk (when you need to clean up) - grep to search inside of files - ip r to find out IP of the router - ping to see if machine on the network / internet is reachable - traceroute maybe? - xprop to find out more about an opened window - lsof maybe in order to see which processes access a file? - chown / chmod maybe? - history - apropos / man - diff maybe - loginctl in case the session seems frozen? - watch .... I'm sure there are a lot more and a lot better examples but they don't come to my mind right now :)
@@AnujRaool you have to install bash-completion but i think is already installed in most distros packages.ubuntu.com/search?keywords=bash-completion But that completion is different than ctrl+R
Its work in every command 5he !! Is just print whatever you print before Lets say you want to change to a directory but you forget to put cd in the start You can just type cd ! ! And it will work
Using the up arrow and typing sudo at the beginning of the line is quick too, if you go to the beginning of the line using Ctrl+a. In some shells the Home key works as well. Ctrl+e takes you to the end of the line, by the way.
I don't know what's hot about sudo !!. I just do Up Home then type "sudo", or alternatively Up Ctrl-A also works as well. That works just fine and uses just as many keypresses. Additionally, it previews the command you're about to run, so much less risky than !! It also fits better with Ctrl-R (reverse-i-search), which !! can't really do.

FYI htop also shows processes in tree form Its "htop -t" You can make alias htop to run htop -t And htop tree shows full path of process instead of just name so its pretty useful when I'm using python virtial environments. I knw exactly which python process is to quit.
An empty SPACE in front of a command makes it skip the BASH history. Perfect to do some housekeeping of your bash history 'as you type'. Because my absolute favourite is CTRL + R to turn the BASH history into an autocomplete interactive session.
Random useful tip that I like: When I compile stuff from github that is not available in my repos, then I use "sudo checkinstall --install=no" first instead of "sudo make install" to be able to easily remove the github stuff through my favourite package manager. (Usefull for when sudo make uninstall does not work properly)
Why even install software globally if you do not have to? If I can run something in place I do. I'll just make a script to launch it and put that on my personal path. Learn to live in your home directory. Then crap won't get shotgun scattered all throughout your OS.
A fun little thing about that TTY bit: It's just a "virtual" console. Linux can manage dozens of these things, and if you're sitting at a Linux install in your DE right now, you're already logged into a TTY. You can do anything here you could do anywhere else, including typing startx to get into your UI. Even when you already have your DE up and running in a different TTY! Meaning you can have multiple users logged in different TTYs, or even the same user for that matter. Back in Ye Olde Days people would connect to different TTYs over serial to interact with the system. This is how deep in the roots of Linux the whole multi-user thing is. On my server, I actually run the UI session in one TTY while server terminal apps are running in others. It means I can log in and out of any user I want in the UI, open a bazillion console instances there to do whatever I need to, all while my server software is just quietly humming away in the background, probably tucked away in a tmux instance, completely unconcerned. ...And I'm just a novice, I can't imagine what people who have a better grasp of linux can do with this kind of flexibility.
Learned a few thing there, thanks, including some surprisingly basic things, like shortcut for system monitor instead of htop, sudo !!, and even combination of lsblk and then blkid! In particular the ctrl-alt F7 to get back to normal window after mucking in tty.
I love these top videos. I switched to Linux fully around 6-7 months ago and I challenge myself to learn something new at least a few times a week. Alias’ for directories is an awesome idea. Idk why I never thought of that lol
A few more: $ ps afx shows the full tree of your processes in the terminal $ df -h shows sizes and available space on all mounted devices $ free -h shows memory status (but the same information is available in top too) and couple pushd/popd allow jumping from directory to directory and return back
For auto-mounting drives instead of editing fstab directly I just use gnome-disks utility and edit the mount options. Makes auto unencrypting drives easy as well so I only need to remember my bootup drive password and I can keep the rest in Bitwarden in case I forget them
I did not know about !! thats gonna save me time from all the sily spelling mistakes. Also I use bashtop rather than htop as its a slightly more user friendly terminal monitoring tool. Thanks again for the great tips
The most important Linux tip in my opinion: use timeshift or something like that. Tinkering is a great way to learn, but when you inevitably mess things up, it's nice to be able to restore a snapshot.
I don't mess computers up. In the 30+ years I've been running them it's only happened like once. OK there was that time when I was setting up a parallel libc but I knew that was going to go bad. I did get that to work eventually too. I wanted to run KDE on Slackware and at the time Slack did not support glibc2. I was not going to run Red Hat either! You're pink to Bob.

Hi Chris, Thanks a lot! For me as a beginner, this is very helpful. I've learned a lot from your videos. Thanks for sharing your knowledge and improve others people life!
A cool tip on the command line is if you want to clear the line you hit ctrl-k from the beginning of the prompt. #> I just typed a bunch of junk and want to start over. Home Key, Ctrl-k
In Terminal xkill lets you kill a process without needing to know its official name. Type xkill & enter, then click the window of the process (e.g. vlc) you want to stop.
7:38 It's CTRL+ALT+F3 on my (as default) Ubuntu 20.04.2 LTS - *not* CTRL+ALT+F1, as you say. Neither does CTRL+ALT+F7 get me back to terminal shell . . . With that command my system is stuck on the disk block checking - and stays there.
You youngin's be lazy. In the olden days we had to do a ps -aux | grep to find the process number and then do the kill -9 to take care of those hung processes.
try pkill instead of killall! Always pivot to root from another user on another machine, don't permit root login on ssh also gets you an audit trail on the other machine.

An extra interesting tool that replaces noMachine for Linux. Its x2go. Its a fork by the times NoMachine was open source. It is very easy to set up and use.
I'd like to see you do some videos on the following: Bash Doing bash scripts with IF statements, which can make them have selections and help modes. like typing the name of the script with the typical ---h after it. I use bash for many things, but mostly to ssh into two different local computers all of the time, and notes on samba and terminal use. These bash scripts are in the path, so they can be called up just like a command, like "linux terminal" calls up my notes on commands used in the terminal. I used "linux terminaledit" to edit that file to put in the tip you gave on the Matrix screen. The ssh command is "s lucid" for may machine lucid and "s dragon" for my machine called dragon. Both are the same bash script, but the $1 string to call up different computers. This is the same with my "linux terminal" or "linux samba" call up is the same bash script that can call up 5 different sets of notes with one script or edit any one of them in nano. Before doing a script, make sure it isn't a command already on the computer. CRON Use of the cron directories to run scripts to back things up. I know you did the command line cron, but these can run whole scripts, which wouldn't fit on a command line. Also these scripts can write the run status to a file, like did it work and how. LOCAL Also I see people advice others to "ssh 192.168.0.41", when they could do "ssh lucid.local" (where lucid is the computer name and local makes ssh look it up in your router) to do the same thing on the local network. That is much easier to remember. Also doing ssh -X lucid.local will make it so you can pull up things like the file or web browsers as a GUI. Dragon has my folding on it for the Cronavirus, and it is in the other room. I can see what the status without leaving my man cave by typing s dragon, which does the ssh -X dragon.local command. Then I pull up Firefox. Aliases are easier than doing scripts. if it is a one line command. I got tiered of typing in "echo $PATH" so now it's just path, an alias, which is easier to remember than "echo $PATH." I have no idea where they got the idea to make it more complicated than just typing in path. Also launchers and places in the task bar.
I'd suggest using a separate .bash_alias file and sourcing it within .bashrc (source ~/.bash_alias) Also I always install sox, nano, imagemagick, tmux, w3m/lynx and your preferred mailutils package (snail, mail, mailx etc) or even alpine/cone/mutt so you have a usable environment should X fail (or if not using X) Oh and use bash functions

I set it to shut down but it does nothing crtl Tab to switch windows inside apps doesn't work either
Did you know about jump? Perhaps you don't need a big CD alias but just a magic CD command that jumps to previously cd'd directories based on a fuzzy search. Install jump, set it up and type in j pi to jump to for example your pictures folder from anywhere if you've previously cd'd into it. It will basically keep a history of directory structures. And uses fuzzy search for those directories. For example I type j dev to go to my Development folder that I have in my home folder
Chris, now that I'm actually paying attention, I now seen how to make the fancy prompt. Too bad I missed that older video. Guess I need to go back and watch all your videos. Thanks for your great tips. (Plus I enjoy your occasional sarcasms) ;-)
'cd -' allows you to flip between directory locations on the FS. e.g. If you 'cd /etc/' from the '$HOME', then 'cd -', will bring you back to $HOME; Do 'cd -' again, and end up at '/etc/'
calc is a pretty nice calculator application , the normal graphical calculators are pretty boring in comparison, you can't even do algebra in most of them.
I find the package manager, software manager, update manager and I think maybe install manager confusing. Also, when start with the Debian vanilla - how do we add other than package manager? Thanks.
Depends on what computer I'm on, ZSH is cool, but I really don't care if it is bash or zsh. ZSH is a bit faster with the plugins like auto complete and other shortcuts, but Bash is already there and I just didn't feel like reinstalling it hehe.

Excellent video, switched to Linux about a year ago. I have watched a lot of videos and gotten a lot of tips. I have to say there were 3 or 4 I did not know. Thank you. One question: What is the CLI command for the system monitor in debian?
Systemd.automount www.freedesktop.org/software/systemd/man/systemd.automount.html If you put systemd.automount in fstab the mounting is posponed to the first usage of the filesystem. For example if you do automount in your net fs, It won't block the boot and It will be mounted after you do a ls folder. We can call it "on demand mounting" if you wish.
Hi Chris, thanks a lot for your tips as always! Some times my Linux Mint just freezes with no responses to any keys or mouse movement. Do you have any keys combinations to restart Linux at once? Cheers.
Great tips; I add my aliases at this location. ~/.bash_aliases so I don't have to clutter my .bashrc and just have one place for all my aliases. Only tip I can think of is the virtual keyboard. Where your actual keyboard is on a blink or some keys just don't work, where you have to replace your keyboard. But if you don't have a spare around or just have to get what every you have to do to finish up a project. For the time being you can bring up your virtual keyboard to continue typing without a real keyboard. Lot of people don't know about this. Which my is call onboard to bring up my virtual keyboard. hopefully those keys work for you or at least your hotkeys can bring it up for the time being. My hotkeys are set as Ctrl + T(continue typing). As long your mouse works, you can continue to type with your virtual keyboard. Even go to the menu with your mouse to bring up the onboard application to continue to type, if your real keyboard is on the blink.
ctrl + a - move cursor to beginning of line in terminal
ctrl + e - move cursor to end of line in terminal
thx you ctrl e is saving my life
Thank you my keyboard shortcut warrior!
With this I shall rule the world!
Fn+left. (right) combination also works for same..😋
^p and ^n for previous and next line, ^w to kill last word, ^y to yank last word (yes, cut and paste work in the terminal, without the mouse, but don't share the mouse kill buffer).
ctrl u to delete the whole line, ctrl t to switch places of the 2 last letters behind the cursor, ctrl shift c/v to copy and paste in the terminal; obv there are more shortcuts.
also you can write to a file without opening it using "echo banana > file.txt" the > symbol will delete all in the file and write what you want, you can append with >>.
you can use the output of a command as a command itself by entering the command in "$(command)" and you can redirect standard output in standard input with the | symbol (e.g find banana | grep something).
these are just some useful tricks to do stuff in a faster way

A cool tip on the command line is if you want to clear the line you hit ctrl-k from the beginning of the prompt.
#> I just typed a bunch of junk and want to start over.
Home Key, Ctrl-k
Over my head but fascinating to watch.
Loved the sudo !!
In Terminal xkill lets you kill a process without needing to know its official name. Type xkill & enter, then click the window of the process (e.g. vlc) you want to stop.
wow this was the full enchilada. great job.
sudo !! Awesomeee! Thanks man!
7:38 It's CTRL+ALT+F3 on my (as default) Ubuntu 20.04.2 LTS - *not* CTRL+ALT+F1, as you say.
Neither does CTRL+ALT+F7 get me back to terminal shell . . . With that command my system is stuck on the disk block checking - and stays there.
Probably MATE is what is causing you trouble with VLC. Try KDE or XFCE4 please. People vote up please.
This was a fantastic vid. I learned a lot here. More info on. Commands such as editing the prompt to look good, or, the sudo !!
You youngin's be lazy. In the olden days we had to do a ps -aux | grep to find the process number and then do the kill -9 to take care of those hung processes.
Excellent!
try pkill instead of killall! Always pivot to root from another user on another machine, don't permit root login on ssh also gets you an audit trail on the other machine.
Thanks for making these videos fun. Your awesome. I have first time moved over from win 8 to Linux mint and all your videos really help. There are other content creators but honestly they are a bore to watch. You rock amigo. Keep it up. 👍
!! gives you last command. If you type history - each typed entry has a . Type ! to execute that command.
I think new users should know more about ttys and runlevels. I would like to be reminded how to add and subtract virtual consoles- ttys. At least text ones.
Ctrl + Alt + F1 - F12 for ttys, either F1 or F7 is your graphical session.
@@justsomerandompersononthei2595 No, I mean if there is only 6, create more or if there is 12, and I want 6, remove them. Also change which are GUIs, which are system logs, etc.
How did you get VLC dark mode?
Thanks Chris! Great stuff!
An extra interesting tool that replaces noMachine for Linux. Its x2go. Its a fork by the times NoMachine was open source. It is very easy to set up and use.
Which one is the better way? open the fstab or #mount -a.?
This is very useful indeed. Thanks for that ! Cheers
I'd like to see you do some videos on the following:
Bash
Doing bash scripts with IF statements, which can make them have selections and help modes. like typing the name of the script with the typical ---h after it. I use bash for many things, but mostly to ssh into two different local computers all of the time, and notes on samba and terminal use. These bash scripts are in the path, so they can be called up just like a command, like "linux terminal" calls up my notes on commands used in the terminal. I used "linux terminaledit" to edit that file to put in the tip you gave on the Matrix screen. The ssh command is "s lucid" for may machine lucid and "s dragon" for my machine called dragon. Both are the same bash script, but the $1 string to call up different computers. This is the same with my "linux terminal" or "linux samba" call up is the same bash script that can call up 5 different sets of notes with one script or edit any one of them in nano. Before doing a script, make sure it isn't a command already on the computer.
CRON
Use of the cron directories to run scripts to back things up. I know you did the command line cron, but these can run whole scripts, which wouldn't fit on a command line. Also these scripts can write the run status to a file, like did it work and how.
LOCAL
Also I see people advice others to "ssh 192.168.0.41", when they could do "ssh lucid.local" (where lucid is the computer name and local makes ssh look it up in your router) to do the same thing on the local network. That is much easier to remember. Also doing
ssh -X lucid.local will make it so you can pull up things like the file or web browsers as a GUI. Dragon has my folding on it for the Cronavirus, and it is in the other room. I can see what the status without leaving my man cave by typing s dragon, which does the ssh -X dragon.local command. Then I pull up Firefox.
Aliases are easier than doing scripts. if it is a one line command. I got tiered of typing in "echo $PATH" so now it's just path, an alias, which is easier to remember than "echo $PATH." I have no idea where they got the idea to make it more complicated than just typing in path.
Also launchers and places in the task bar.
I liked the htop and killing processes. I couldn't figure out how to do that yesterday so I restated my computer.
I'd suggest using a separate .bash_alias file and sourcing it within .bashrc (source ~/.bash_alias)
Also I always install sox, nano, imagemagick, tmux, w3m/lynx and your preferred mailutils package (snail, mail, mailx etc) or even alpine/cone/mutt so you have a usable environment should X fail (or if not using X)
Oh and use bash functions
so we create a ~/.bash_aliases file and add source ~/.bash_aliases to .bashrc in the user's home directory?
Noob here!
@@tonyravindran exactly right, then either manually source the .bashrc file for it to source the aliases file, or log out then log in
You can type xkill in the terminal and click in the program for killing it.
golden hotkeys
windows E - Nemo
windows right - snap window to the right
windows left - snap window to the left
windows up - toggle maximize-restore
windows down - minimize
windows M - minimize all
alt Tab - switch windows
crtl alt right - go to desktop 2
crtl alt left - go to desktop 1
crtl alt up - show all desktops
crtl alt T - terminal
crtl alt End - logoff
unfortunately, crtl alt del does nothing on Cinnamon. I set it to shut down but it does nothing
crtl Tab to switch windows inside apps doesn't work either
windows!? windows key!? There is no windows key on my computers?
Ah, you mean the Arch Key or as some folks call it, the application key! 😂
"xkill" and click what you want to kill :) also F5 in Htop gives you tree view
You really should make a video about autofs. It takes a little work to set up but I think it's a lot slicker than using fstab
Out of curiosity what terminal are you using? It's really easy on the eyes
Did you know about jump? Perhaps you don't need a big CD alias but just a magic CD command that jumps to previously cd'd directories based on a fuzzy search.
Install jump, set it up and type in j pi to jump to for example your pictures folder from anywhere if you've previously cd'd into it. It will basically keep a history of directory structures. And uses fuzzy search for those directories.
For example I type j dev to go to my Development folder that I have in my home folder
Chris, now that I'm actually paying attention, I now seen how to make the fancy prompt. Too bad I missed that older video. Guess I need to go back and watch all your videos. Thanks for your great tips. (Plus I enjoy your occasional sarcasms) ;-)
history, then ! to run command again
'cd -' allows you to flip between directory locations on the FS.
e.g.
If you 'cd /etc/' from the '$HOME', then 'cd -', will bring you back to $HOME; Do 'cd -' again, and end up at '/etc/'
Thanks for all the tips... many I did not know!
what terminal is that? Please and thanks.
Thank you titus you help new user
Wow, since when did UA-cam add the timestamp in progress bar feature?
something like a month ago
please add some tabs to your fstab to make it more readable, it's way more understandable when you can see columns.
calc is a pretty nice calculator application ,
the normal graphical calculators are pretty boring in comparison,
you can't even do algebra in most of them.
What window manager is he using?
Could you possibly do a video on porting Halium onto a device?
I find the package manager, software manager, update manager and I think maybe install manager confusing. Also, when start with the Debian vanilla - how do we add other than package manager? Thanks.
Hey, Chris.
Have you dumped your Zsh shell? :D
Depends on what computer I'm on, ZSH is cool, but I really don't care if it is bash or zsh. ZSH is a bit faster with the plugins like auto complete and other shortcuts, but Bash is already there and I just didn't feel like reinstalling it hehe.
ah yes Z Shell Shell
@@igorordecha Brings back old memories. CD-disk, DAT-tape and so on. At least in my language (CD-skiva, DAT-band, and no, don't try to pronounce it, you'll most likely fail miserably, at least if you are a native English speaker… 😁).
I use "glances" instead of htop on servers. God it's good.
glances and htop are two different but useful beast, lot of htop in glances but not all (that easy)
Why -9 for killall? I don't think that you need that -9. At least not for VLC. I wholeheartedly recommend using workspaces!
Excellent video, switched to Linux about a year ago. I have watched a lot of videos and gotten a lot of tips. I have to say there were 3 or 4 I did not know. Thank you. One question: What is the CLI command for the system monitor in debian?
Systemd.automount
www.freedesktop.org/software/systemd/man/systemd.automount.html
If you put systemd.automount in fstab the mounting is posponed to the first usage of the filesystem.
For example if you do automount in your net fs, It won't block the boot and It will be mounted after you do a ls folder.
We can call it "on demand mounting" if you wish.
Hi Chris, thanks a lot for your tips as always! Some times my Linux Mint just freezes with no responses to any keys or mouse movement. Do you have any keys combinations to restart Linux at once? Cheers.
@gilkesisking Cheers bro! You are a gentleman! :)
@gilkesisking thanks a lot once again! Just tried and it works just fine! God bless!
@gilkesisking cheers bro! Will listen for sure these Linux-Gods! :)))
Great tips; I add my aliases at this location. ~/.bash_aliases so I don't have to clutter my .bashrc and just have one place for all my aliases. Only tip I can think of is the virtual keyboard. Where your actual keyboard is on a blink or some keys just don't work, where you have to replace your keyboard. But if you don't have a spare around or just have to get what every you have to do to finish up a project. For the time being you can bring up your virtual keyboard to continue typing without a real keyboard. Lot of people don't know about this. Which my is call onboard to bring up my virtual keyboard. hopefully those keys work for you or at least your hotkeys can bring it up for the time being. My hotkeys are set as Ctrl + T(continue typing). As long your mouse works, you can continue to type with your virtual keyboard. Even go to the menu with your mouse to bring up the onboard application to continue to type, if your real keyboard is on the blink.
