The tutorial of how to install oh-my-zsh

1. You need to install Zsh first:
   • sudo apt install zsh
     • if you get an error (dpkg was interrupted) you must run this command: sudo dpkg --configure -a
2. Verify installation:
   • zsh --version
3. You need to make it your default shell:
   • chsh -s $(which zsh)
4. You need to log out and login:
   • Test that it worked
     • echo $SHELL If your result is /bin/zsh or similar then you're good to go
   • Do another test
     • $SHELL --version Expected result is zsh 5.4.2
5. Installing oh-my-zsh:
   • You can use curl
     • via curl

         sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

6. Download the .zshrc file to your HOME directory

   • If it's done change the USER part to yours:

     export ZSH=/home/<USER>/.oh-my-zsh

     It will look something like this:

     export ZSH=/home/theuserijusttyped/.oh-my-zsh

OPTIONAL PART

7. Plugins:
   • You can use the .zshrc file I uploaded to github it uses:
     • git
       • adds a lot of aliases, see here
     • sudo
       • if you forgot to write sudo before some command you can easily put it by pressing the ESC key twice
     • docker
       • gives autocomplete support
     • docker-compose
       • gives autocomplete support
     • history
       • if you type h (history) oh-my-zsh will show you the command-history
     • history-substring-search
       • if you start typing in any previous command (part of it) and hit UP key then the similar one will be shown

Other (useful) features

From ZSH

• no need to type cd to change directory
  • you can simply type in the correct folder name and press ENTER to... well... ENTER to the directory
  • this is same for leaving a directory as well
    • simply type in .. instead of cd ..

From oh-my-zsh

• typing l is like typing in ls -a

Custom

• tre is a shorthand for tree with hidden files and color enabled
• reload will reload your terminal window and you don't need to close and reopen after modifying your environment
