Bash Tutorial!

A brief overview of Bash, on your way to becoming a Linux expert. When a computer boots up, a kernel (MacOS, Windows, Linux) is started. This kernel provides a shell that allows user to interact with a most basic set of commands. Typically, the casual user will not interact with the shell as a Desktop User Interface is started by the computer boot up process. To activate a shell directly, users will run a “terminal” through the Desktop. VS Code provides ability to activate “terminal” while in the IDE.

Prerequisites

Setup bash shell dependency variables for this page.

  • Hack: Change variables to match your project.
%%script bash

# Dependency Variables, set to match your project directories

cat <<EOF > /tmp/variables.sh
export project_dir=$HOME/vscode  # change vscode to different name to test git clone
export project=\$project_dir/teacher  # change teacher to name of project from git clone
export project_repo="https://github.com/nighthawkcoders/teacher.git"  # change to project of choice
EOF
%%script bash

# Extract saved variables
source /tmp/variables.sh

# Access the variables
echo "Project dir: $project_dir"
echo "Project: $project"
echo "Repo: $project_repo"

Project dir: /Users/johnmortensen/vscode Project: /Users/johnmortensen/vscode/teacher Repo: https://github.com/nighthawkcoders/teacher.git

Setup Project

Pull code from GitHub to your machine. This script will create a project directory and add “project” from GitHub to the vscode directory. There is conditional logic to make sure that clone only happen if it does not (!) exist.

%%script bash

# Extract saved variables
source /tmp/variables.sh

echo "Using conditional statement to create a project directory and project"

cd ~    # start in home directory

# Conditional block to make a project directory
if [ ! -d $project_dir ]
then 
    echo "Directory $project_dir does not exists... makinng directory $project_dir"
    mkdir -p $project_dir
fi
echo "Directory $project_dir exists." 

# Conditional block to git clone a project from project_repo
if [ ! -d $project ]
then
    echo "Directory $project does not exists... cloning $project_repo"
    cd $project_dir
    git clone $project_repo
    cd ~
fi
echo "Directory $project exists." 

Using conditional statement to create a project directory and project Directory /Users/johnmortensen/vscode exists. Directory /Users/johnmortensen/vscode/teacher exists.

Look at files Github project

All computers contain files and directories. The clone brought more files from cloud to your machine. Review the bash shell script observe the commands that show and interact with files and directories.

  • “ls” lists computer files in Unix and Unix-like operating systems
  • “cd” offers way to navigate and change working directory
  • “pwd” print working directory
  • “echo” used to display line of text/string that are passed as an argument
%%script bash

# Extract saved variables
source /tmp/variables.sh

echo "Navigate to project, then navigate to area wwhere files were cloned"
cd $project
pwd

echo ""
echo "list top level or root of files with project pulled from github"
ls

Navigate to project, then navigate to area wwhere files were cloned /Users/johnmortensen/vscode/teacher

list top level or root of files with project pulled from github Gemfile Gemfile.lock LICENSE Makefile README.md _config.yml _data _includes _layouts _notebooks _posts _site csa.md csp.md csse.md images index.md indexBlogs.md nohup.out scripts

Look at file list with hidden and long attributes

Most linux commands have options to enhance behavior

ls reference

%%script bash

# Extract saved variables
source /tmp/variables.sh

echo "Navigate to project, then navigate to area wwhere files were cloned"
cd $project
pwd

echo ""
echo "list all files in long format"
ls -al   # all files -a (hidden) in -l long listing
  • Basically just lists all of the hidden files in a certain directory

Look inside a Markdown File

“cat” reads data from the file and gives its content as output ```bash %%script bash

Extract saved variables

source /tmp/variables.sh

echo “Navigate to project, then navigate to area wwhere files were cloned”

cd $project echo “show the contents of README.md” echo “”

cat README.md # show contents of file, in this case markdown echo “” echo “end of README.md”

## Blog site using GitHub Pages and Jekyll
> This site is intended for Teachers.   This is to build lessons and distribute across different sections.
- This support 3 computer science sections that are in a pathway (JavaScript, Python/Flask, Java/Spring)
- JavaScript documents are new material for entry class into the pathway, they are prerequisites for the Python and Java classes.
- All course material works off of Notebooks using Python kernel, except Java which requires it own kernel.

## Preview Site 
> GitHub Pages development is optimized by testing and developing on your local machine.  This is called previewing you work, prior to commit and push. 
- GitHub setup for, [Testing your GitHub Pages site locally with Jekyll](https://docs.github.com/en/pages/setting-up-a-github-pages-site-with-jekyll/testing-your-github-pages-site-locally-with-jekyll).  After requirements are met for Jekyll and Ruby you need to install requirements for project.
```bash
bundle install
  • Now the project is ready for preview. To simplify typing and sharing logging the details for running have be place in a Makefile
    • run preview server
        make
      
    • stop preview server
        make stop
      
    • test notebook conversions … make clean ```

This introductory paragraph and this line and the title above are generated using tee with the standard input («) redirection operator.

  • This bulleted element is still part of the tee body.
  • This bulleted element and lines below are generated using echo with standard output (») redirection operator.
  • The list definition, as is, is using space to seperate lines. Thus the use of commas and hyphens in output. - ls: list directory - cd: change directory - pwd: present working directory - if then fi: test condition - env: bash environment variables - cat: view file contents - tee: write to output - echo: display content of string - echo “sample text” >$file: write content to file - echo “sample text” »$file: append content to file

    Env, Git and GitHub

    Env(ironment) is used to capture things like path to Code or Home directory. Git and GitHub is NOT Only used to exchange code between individuals, it is often used to exchange code through servers, in our case deployment for Website. All tools we use have a behind the scenes hav relationship with the system they run on (MacOS, Windows, Linus) or a relationship with servers which they are connected to (ie GitHub). There is an “env” command in bash. There are environment files and setting files (.git/config) for Git. They both use a key/value concept.

  • “env” show setting for your shell
  • “git clone” sets up a director of files
  • “cd $project” allows user to move inside that directory of files
  • “.git” is a hidden directory that is used by git to establish relationship between machine and the git server on GitHub.

Student Request - Make a file in Bash

This example was requested by a student (Jun Lim, CSA). The request was to make jupyer file using bash, I adapted the request to markdown. This type of thought will have great extrapolation to coding and possibilities of using List, Arrays, or APIs to build user interfaces. JavaScript is a language where building HTML is very common.

To get more interesting output from terminal, this will require using something like mdless (https://github.com/ttscoff/mdless). This enables see markdown in rendered format.

Output of the example is much nicer in “jupyter”

%%script bash

# This example has error in VSCode, it run best on Jupyter
cd /tmp

file="sample.md"
if [ -f "$file" ]; then
    rm $file
fi

Blog site using GitHub Pages and Jekyll

This site is intended for Teachers. This is to build lessons and distribute across different sections.

  • This support 3 computer science sections that are in a pathway (JavaScript, Python/Flask, Java/Spring)
  • JavaScript documents are new material for entry class into the pathway, they are prerequisites for the Python and Java classes.
  • All course material works off of Notebooks using Python kernel, except Java which requires it own kernel.

Preview Site

GitHub Pages development is optimized by testing and developing on your local machine. This is called previewing you work, prior to commit and push.

  • GitHub setup for, Testing your GitHub Pages site locally with Jekyll. After requirements are met for Jekyll and Ruby you need to install requirements for project.
    bundle install
    
  • Now the project is ready for preview. To simplify typing and sharing logging the details for running have be place in a Makefile
    • run preview server
        make
      
    • stop preview server
        make stop
      
    • test notebook conversions … make clean ```

Hack Preparation.

Review Tool Setup Procedures and think about some thing you could verify through a Shell notebook.

  • Come up with your own student view of this procedure to show your tools are installed.
  • Name and create notes on some Linux commands you will use frequently: ls and cd (do go back to directory the current directory is in, do cd..)
  • Is there anything we use to verify tools we install? Review versions checks.
  • Is there anything we could verify with Anaconda? or WSL?
  • How would you update a repository? Could you do that in script above? I would usually just update the repository through git commands and gui, like push then commit and just push again. But sometimes when necessary, I will use the script.
