https://youtu.be/F0mHnwTrNNc When you get many splits going in tmux sometimes its time for a new layout. There are four layout strategies that I use, main-vertical, main-horizontal, even-vertical, even-horizontal. Almost always I am useing the main ones with mod plus a or mod plus shift a keybindings.

https://youtu.be/hpFYE2LU7xc Resizing panes in tmux can be quite difficult in default tmux, I use a set of keybingings to help resize panes in the rare occasions that I do need just a bit more space. I set the keybinding to the same as my split navigation bindings but shifted. They are very vim like (h,j,k,l). Most often when I need to resize panes I just grab the edge of the pane with my mouse. Yes the mouse, its not that often that I actually need to change the size of a pane. How I navigate tmux in 2021 for more information on how I navigate tmux, check out this full post

https://youtu.be/BMkpbfhbkKM The prefix key is an essential part of tmux, by default all of tmuxâs key-bindings sit behind a prefix. This prefix is very similar to vimâs leader key. It is common for folks to change the default (control b) to or if they are a vim user something to match their vim leader key. A few of the essential default key-bindings.

https://youtu.be/kzgyiHap1nQ splitting panes is a core feature of tmux. It allows us to split the terminal vertically or horizontally into new panes. đď¸ note that â#{pane_current_path}âwill keep the split in the same directory as itâs parent, without this it will default to your home directory.

https://youtu.be/RB87EEnnMnU An ultimate productivity key-binding in tmux is one to switch to the last session. I use this to quickly get between sessions really quick. Often I am working and need to lookup a quick note, or copy something into my notes, then get back to where I was quickly. I think of this hub and spoke model, and use to quickly drive it.

https://youtu.be/2ZqFDsJywt8 Tmux popups are actually floating windows that you can drag around the screen. They always open in the middle (by default) when you open them, no matter where you leave them. Here are a couple of keybindings I use to open up popup windows.

In 2021 I changed the way I navigate between tmux sessions big time. Now I can create, kill, switch with ease, and generally keep work separated into logical groups. Update Since making this post, I have made ~20 other posts in short form that all have a YouTube video to go along with them you can find them all on my tmux-playlist. Chris Toomeyâs Tmux Course I took Chrisâs tmux course in December 2020 and it was fantastic. Even as a seasoned tmux user, I learned quite a bit. Before the course, I was proficient in navigating within each of my tmux sessions but rarely started more than one session. A few months later, I have adopted a lot of what I learned from Chris and made it my own. I am now keeping projects to their own session and can move between them fluidly with just a few keystrokes. For high-traffic projects, I have them bound to a single keystroke for instant switching. This change has been a game-changer from the mess of windows I used to have and the nightmare it was to finâŚ

Creating a directory that is a union of several directories can be achieved with a few symlinks at the command line. Creating a Virtual File Gallery Here is how I am creating a virtual directory of all my projects that is a combination of both work and not-work projects. I am creating symlinks for every directory under and. â Notice that first I am recreating the directory each time. This will ensure that any project that is deleted from their actual directory is removed from the virtual gallery. Updating the gallery Since links are always kept up to date without any extra work, all the data is still in the same place it started. But as new directories are added to any project directory they will not be automatically added to the virtual gallery. cron bashrc/zshrc If youâre concerned about system resources, you can add it to a cron job to run at a regular schedule that makes sense to you.

You get a four hour session for free, after four hours everything will be deleted, but you can start a new session. Installing Docker on Linux Installing on Ubuntu. Running Docker commands without sudo In order to run docker commands without using sudo you need to add docker to your group. Architecture and Theory Container - Isolated area of an OS with resource usage limits applied. Namespaces and Control Groups are hard, which is why containers were unusable by mortals before docker. Namespaces Isolation Each container looks and feels like a regular OS. It has its own eth0, users, kernel. These are completely isolated from every other container running on the system. Namespaces are analogous to what Hypervisors do on hardware. Process ID (pid) Network (net) Filesystem/mount (mnt) Inter-proc comms (ipc) UTS (uts) User (usr) ControlâŚ
Replacing text in vim can be quite frustrating especially since it doesnât have live feedback to what is changing. Today I was watching Josh Branchaudâs Vim-Unalphabet series on Youtuve and realized that his vim was doing this and I had to have it. https://twitter.com/_WaylonWalker/status/1346081617199198210 How to do it I had to do a bit of searching and found a great post from vimcasts that shows exactly how to get the live search and replace highlighting using:h inccommand Add this to your config I believe that this is a neovim only feature, add it into your file. You can see it in my dotfiles as well. See it in Action example live substitution The Video that inspired this Check out Josh Branchaudâs great series on the Vim-Unalphabet. https://www.youtube.com/watch?v=5jMiYtXz2QA

Bash is a language that is quite useful for automation no matter what language you write in. Bash can do so many powerful system-level tasks. Even if you are on windows these days you are likely to come across bash inside a cloud VM, Continuous Integration, or even inside of docker. I have three techniques that help me write more composable bash scripts. functions Arguments positional arguments All Arguments Error Handling main script Functions Break scripts down into reusable components Functions in bash are quite simple. They are something that I wish I would have started using long ago. They make your code much more reusable. I often use them in my aliases as well since they can simplify the process and allow more flexibility. syntax Source the file to load the function and run it from the terminal. run it outputs Arguments Make functions a little more flexible Arguments and options are quite a bit more complex in bash.
