Inside my iPad Pro SSH Setup - TMUX

[@jeffreyhunter4115]

This may be the day where I make the switch from ‘screen’ after many decades! Great video. Very well organized.

[@tech_craft]

I moved over to tmux from screen many, many years ago and I haven't looked back. I remapped Ctrl-A to the prefix for a while before deciding I wanted to locate it somewhere more convenient, but I think it helped with the move.

[@paulmesaric5059]

Love the way you layout your videos, intro, tours and timestamps

[@smoocher]

I've recently started using my iPad as my main laptop and have been using one terminal window to connect to my Pi. This will help a lot. Thanks!!

[@fredlaxton]

I used to use screen for many years, until it was abandoned. I switched to tmux with little pain, remapping it to use Ctrl-a as the prefix, like screen (muscle memory!). Instead of using ssh directly, I use mosh, which uses ssh internally to connect. Why mosh? Because you can close your laptop, iPad, whatever on one network, go somewhere else where you’re on a different network. Open it back up and your mosh connection is still working. No more dead ssh sessions! Also, it will predict feedback and type it on the screen, even on a slow connection, so it makes slow connections “feel” faster than they really are. I did learn a few tricks, especially about the status line customization. I’d been doing it the hard way with powerline - I will give this a try. Great video!

[@tech_craft]

Fully agree with the mosh sentiment - I covered that in my previous video.

[@fredlaxton]

@@tech_craft AND I too had done this tmux status line the hard way. I got it set up on Linux and then couldn’t duplicate it on Mac. Following your instructions, I threw out my old powerline mods and got it set up with Dracula in about 10 minutes. THANK YOU!

[@Oscar-ni3fx]

Great video as always. A small suggestion that would have been helpful for this video. Blink has keycast, which shows on screen the keys you are pressing. For regular videos where what’s important is the text you are typing, it does not matter, but here it could have been useful to show the sequence of prefix+shorcut. Blink even lets you toggle keycast with a keyboard shorcut so you can activate it only when necessary.

[@PowerLlama]

not sure if it's mentioned in the comments, but something that helped me remember the prefix is that "b" stands for "buffer". so Buffer-o to cycle etc

[@chirpybee]

Been using Tmux for years and ashamed to admit I had never used a number of these options. Thank you 👍

[@MelRiffe]

I've been using tmux for a while, but not consistently. Because of your video I'll be doing some customizations, especially mouse support. And, until you mentioned it, I hadn't thought to start tmux sessions on my Linux SSH sessions. IMHO, a great tip right there. Thanks!

[@micleh]

Never bothered about using tmux, but you had me sold right from the start. I enjoyed every bit of your explanation and your selection of shortcuts and configuration items felt sensible through and through. Thanks so much for another extremely helpful video.

[@tech_craft]

I don't think you'll regret giving tmux a whirl. The more you use it, the more it becomes like second nature.

[@夕阳-n1h]

Such a great video. Thanks for making this, was able to start from never having used tmux to complete setup in under 30 mins.

[@traal]

I've been using GNU screen instead for decades... This video finally gave me the push to switch over to tmux. No major problems yet, so I think it'll work. 😊

[@tech_craft]

I was screen user too. I do think tmux is a nice upgrade and I hope you'll not be disappointed!

[@dmitrykhangulyan4349]

I like this channel -- it is so much fun to listen to the explanations of why the tools I use (xmonad, tmux, etc) are the best.

[@prgnify]

I used to use TMUX because it was simply the first thing that showed up when I looked for what I wanted/needed to do. But one day it hit me > "I have a thousand lines long vimrc that simply goes to waste when I'm remoting somewhere, especially if all there is is vi". That was when I started using EMACS, of course with evil mode. Since you can open terminals and run a multiplexer from inside emacs, you can just use your editor on literally everything.

[@ViniciusProvenzano]

fantastic Tech Craft, and you make your setup look SOOOOOOOO beautiful

[@GPTkhan]

broken it down makes it seem so user-friendly and easy to use. I can’t wait to start making soft! Thanks again!

[@JEROENHAHAHA]

My left ear really enjoyed this informative video.

[@nathanaelculver5308]

I also remap CapsLock as Ctrl, then A as the prefix key, making it super-convenient.

[@nathanaelculver5308]

Good video, as always. But what I’d really like to see is a tutorial on automation and inter-pane and inter-window communication, such as sending commands to other panes. You could, for example, script the creation of a tmux layout and launch and control apps in other panes, and so forth.

[@ryanmchale8902]

How do you do this?

[@nathanaelculver5308]

@@ryanmchale8902 Here’s an example script that will open three panes and send a command to each. You’ll need to run the script from within TMUX: tmux new-session -d tmux rename-window ‘TMUX-automation’ tmux split-window -v -p 35 tmux split-window -h -p 50 tmux select-pane -t 0 ; tmux send-keys ‘echo THIS IS PANE 0’ C-m tmux select-pane -t 1 ; tmux send-keys ‘echo THIS IS PANE 1’ C-m tmux select-pane -t 2 ; tmux send-keys ‘echo THIS IS PANE 2’ C-m tmux -2 attach-session

[@joaopauloalbq]

I use tiling window manager (Awesome) which has similar behavior but can be used in GUI programs too, it's the most productive environment!

[@billeterk]

Ooh.. I’ll have to check out plug-ins. It took me a little while to find a free enough key combo for a prefix but have settled on ctrl-space which works well with space as vim leader too.

[@navajyoth814]

Hey Rob, fantastic video as usual! I am really interested in how you customized your shell. Mind doing a video on that or sharing the dotfiles?

[@tech_craft]

I have this video that covers most of the shell setup: kzbin.info/www/bejne/bn3GhXRropuSqtU - if you have questions you can get me on Twitter @tech_crafted

[@doomikusz]

Please consider either going stereo or dual-mono. Thank you for your videos

[@tech_craft]

This issue has been fixed on my latest video. I have a new camera and it's taken me a while to get it sorted.

[@micleh]

Hi. As to tux and macOS, are you aware that the tmux keyboard combinations can be remapped to match those commonly used in macOS (and other OSs)?. There is a great tutorial by Josh Medeski called "macos keyboard shortcuts for tmux". Thought this info might be interesting.

[@tech_craft]

Nice idea. I've gone the other way - I use the same shortcuts I have in my XMonad setup on the Mac.

[@theloniuser]

Fantastic video. I have done all of this and am excited to use in my workflow. I am getting question marks in the powerline ststus bar at the bottom despite having install what I thought were the correct fonts. Also, I noticed that all sessions disappear on reboot. Thanks!

[@tech_craft]

Sadly sessions won’t survive reboot of the host. The question marks sounds like you have a font that’s missing the powerline characters. Which font is it? It may have a dedicated powerline variant that you can find in NerdFonts

[@theloniuser]

@@tech_craft I'm not sure how to tell which one it's missing.

[@sfuoncall]

I like tmux for the automation that is possible. The one thing that I prefer "screen" over tmux is that screen can: 1. Save the output to a log file. 2. You can scroll back. screen is only full screen unlike tmux that lets you create panes.

[@sfuoncall]

Note: I use both.

[@sfuoncall]

Another Note: I also re-map the prefix from Ctrl-B to Ctrl-Z because I am a heavy vim user.

[@fredlaxton]

You can scroll back with tmux too.

[@sfuoncall]

@@fredlaxton Yeah. I posted a little prematuraly and missed the scroll back. But I still like the log feature to capture the output of long running tasks quickly

[@fredlaxton]

@@sfuoncall I was under the impression that screen was abandoned, right? That was a major factor in me switching to TMUX. Has it had more development?

[@zonnefroske3225]

Thank you so much for sharing your experience with us. God bless you .

[@halemmor]

Which font are you using here? I don’t see it listed in the description. Great video! Been using tmux for a while, albeit very basic setup, but definitely going to incorporate some of the tips and customisations from this video

[@tech_craft]

It’s JetBrains Mono

[@marcelwiget8996]

I'm using Blink with tmux for some time now. The lack of using mouse to resize pane issue I worked around by using the standard ^B and hitting the arrow keys while keeping ^B pressed. This is good enough for me.

[@tech_craft]

Same. I just need the touch to work for my sanity. It really annoys me I haven’t figured it out.

[@totallyperfectworld]

Okay, so how do you combine tmux with mosh in blink - so basically try to attach to an existing tmux session, but if non exists, then create a new session?

[@tech_craft]

Essentially yes. You can configure Blink to launch tmux automatically when you log in. You can use a command like `tmux new -A -s ` to attach to a session,creating it if it doesn't already exist.

[@Klausterfull]

Thanks a ton! Didn't know Tmux had a package manager!

[@x0rZ15t]

TMUX has also different plug-ins that can be managed by TPM (Tmux Plugin Manager). Plugins I use on day-to-day bases are: tmux-sensible tmux-resurrect tmux-continuum tmux-sessionist tmux-logging

[@rul1175]

[@drumpf4all]

[@acafella11Music]

Is this a jail broken iPad? How else is he running a different os?

[@OlaInTheClouds]

Great tips, been using tmux for a while. awesome tool, being able to leave a running session and pick it up again from else where. It's funny how these "old" terminal tools like vi(m) and screen (from 1987) replaced by tmux is having a second coming. GUI dev tools are nice but sometimes you can't use them and need good cmd line alternatives.

[@JaisonMiller]

Cool video, going to give it a go - what do you think of byobu? It’s a bit like a preconfigured tmux install that’s quite nice ‘out the box’ :)

[@linkindescription1183]

[@cppdev2729]

dude u saved my life

[@StefanWolfrum]

Couldn't wait and started immediately. 😂 Problem: after adding the Dracula plugin line to the .tmux.config file, saving it, reloading with ctrl-t r and doing a ctrl-t I - nothing happens. I don't get that fancy status bar that we see in your video. 😞 Am I maybe missing an installation step for the Dracula tmux theme? On the other hand: no extra installation seems to be needed according to their webpage. #bummer

[@StefanWolfrum]

Ohhkayy ... exited the tmux session completely, started a new one, learned that the config file should be named .tmux.conf (not .tmux.config) to be read automatically (because all of a sudden ctrl-t wasn't the command key anymore) and all of a sudden, dracula showed up! 😉

[@StefanWolfrum]

Now even configured the hosts I connect to in Blink so that mosh & tmux starts autmatically, tmux attaching to the last session. Very nice! Now I need a cheat sheet for tmux commands next to my iPad Pro screen! 😂 And I have yet to find my command key because ctrl-t is bound in some tools (like nano) to other functions.

[@billeterk]

@@StefanWolfrum ctrl- is good for me.

[@zestynotions]

Long term user of tmux too, but never tried to tpm plugin manager, brilliant! have you tried the tmuxinator for async session and automation that works with tmux? you can then start predefined tmux environment with panes etc and run commands automatically in those panes. Can also have it create multiple ssh sessions in the panes to update many servers async etc. :)

[@zestynotions]

btw this is also nice to add in your .zshrc or .bashrc on the servers you connect to = tmux attach || tmux new That way on ssh/mosh login you will always automatically connect to the previous tmux session or create a new if one does not exist :)

[@tech_craft]

I was using tmuxinator for a few years, but then I stopped in favour of just leaving the sessions running on machine that I rarely shutdown. I may have to revisit to see what is new though!

[@zestynotions]

@@tech_craft Good point, I guess it is more useful for session management on mac so not very helpful if your primary dev environment is the ipad :)

[@WeilongYou]

I guess my question is, what terminal are you using (that I have to setup) before install tmux...

Been waiting for this video for a while Quick question: do you use homebrew on any of your Pi’s ? Is there any need since it already has a package manager ?

[@tech_craft]

I don't use Homebrew on the Pi because apt is available, but you certainly can use it. I have considered using Linuxbrew and Homebrew as a way of sharing more of my setup across machines.

[@cedricvillani8502]

Blink commercial? I mean of course you can do all this and normally, terminal setups are really old, still use them but there’s so many options and obviously you want to first get Blink. But that’s more of a environment setup like i3w lol or was it iw3, for Linux a free easy one is Terminator

[@tech_craft]

I’m not really certain what your point is. Terminator and i3 don’t run on iPad. The bulk of this video is about tmux and not blink.

[@basilfeitknecht6430]

[@Taddy_Mason]

[@bobsisic5714]

Can you install Tmux on iPad without having to ssh to a network pi

[@tech_craft]

You can try it out with the iSH app, but there's no native support on iPad sadly.

[@niallkelly1577]

you are a legend!

[@acafella11Music]

Noob here. What exactly is he using these terminals for?

[@kalekold]

Forget tmux, just use Terminator as your terminal emulator, it has window splitting and tabs straight out of the box.

[@tech_craft]

A fine option for terminal directly on the machine, but terminator doesn't help with saving remote sessions.

I would love to use Ubuntu on iPad Pro using Raspberry Pi, if you can figure somehow.

[@tech_craft]

I have that working now. I updated the pre-built images with an Ubuntu Server image: github.com/techcraftco/rpi-usb-gadget/ For Ubuntu Desktop, the resulting images are too large for Github. I'm looking for a good hosting alternative, but I'll also post a video with instructions on how to set up Ubuntu Desktop with a nice VNC setup too.

@@tech_craft Why do you need hosting? Make an image on the SD Card. Ubuntu 20.04 natively now supports on Raspberry Pi.

That’s one of my main uses. I run the editor in one tab, then I’m running Eleventy with live preview in another tab. I have my browser window open and basically just get to see the changes live as I make them. For a bit extra I also have tests on auto execute in a terminal tab too. Works a treat.
