Yep, I ran a short "introduction to the command line" course for the devs in my team. Afterwards, I noticed that their usage of the vscode terminal was much higher, and folks were more comfortable exploring on their own.

Quick outline of the course, in case anyone wants a starting point:

  * Introduction
    Quick history of Unix

  * When you log in
    Difference between login and interactive shells
    System shell files vs user shell files
    .zshenv for environment variables like PATH, EDITOR, and PAGER
    .zprofile for login shells, we don't use it
    .zshrc for interactive shells
    Your login files are scripts, and can have anything in them

  * Moving Around

  ** Where am I?
    pwd = "print working directory"
    stored in variable $PWD
    Confusingly, also called current working directory, so you may see CWD or cwd mentioned

  ** What is here?
    ls
    ls -al
    ls -alt
    . prefix to filenames makes them hidden
    . is also the current directory!
    .. means the parent directory
    file tells you what something is
    cat displays a file
    code opens it in vscode

  ** Finding my way around
    cd
    cd -
    dirs | sed -e $'s/ /\\\n/g'

  ** Getting Help From The Man
    man 1 zshbuiltins
    manpage sections

  ** PATH
    echo $PATH | sed -e $'s/:/\\\n/g'
    zshenv PATH setting
    which tells you what will be run

  ** Environment Variables
    env | sort
    EDITOR variable

  ** History
    ctrl-r vs up arrow

  ** Permissions
    Making something executable

  ** Prompts
    zsh promptinit
    zsh prompt -l

  ** Pipes and Redirection
    Iterate to show how pipes work
    cat ~/.zshrc | grep PATH
    ls -al > ~/.tmp/ls-output.txt

  ** Commands

  *** BSD vs GNU commands
    BSD are supplied by Apple, and Apple often uses old versions
    GNU are installed via homebrew, and match those commands available in Linux
