UNIX

UNIX is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, development starting in the 1970s at the Bell Labs research center. The OS made it possible for a lot of users to interact with a single machine at the same time. Before, this was done by a batch process via an operator/administrator.

Rasperry Pi

Raspberry Pi is a small single board computer used for learning basic computer science.

Basic tasks & experiments:

• Logging into the Raspberry Pi
  
• printing with Matrix printer, ascii word-art generator (more), text-to-speech
• creating public_html directory and index.html on the Sandbox (note: remote login not possible)
• modifying texts (bio) through Terminal using Dadadodo and SED (changing and replacing certain characters)
• working with Unix HTML - editor: ne nice editor
• chaining programs a.k.a PIPING (command: |) / concatonate files (command: CAT)

IP adres of the Pi:

145.24.139.127

Copying files from personal machine to Sandbox:

scp file.txt username@145.24.139.127:/home/username

• Basic tasks & experiments:

• Creating and cofigured personal Keys (passphrase) for R-Pi
• Introduction to GIT
• Configuring GIT and working with repositories

How to work with GIT & repositories in UNIX

How to initiate a git repository?

git init

How do I create a (version) commit of my project?

git status
git add (f.e: index.html style.css)
git commit -m "first 2 files of website"
git log

What did change since my last commit?

git diff 
git diff style.css

How do i remove the changes of a file before it gets commited?

git checkout -- style.css
git restore style.css

How do i see what my project looked like in a cetain commit, and how do I go back to where I was (HEAD)? How do I go back in history my changes?

git revert

How do I create a remote and push my changes to that remote?

How do I clone a repository from git.xpub.nl?

git clone (link)

Make your changes and commit

git commit -m 'added new quote'
git commit -a -m 'edited links'

How publish my commit back to the "remote"?

git push 

How do I avoid conflicts?

git pull origin master

Before you go back to working on projects, where you are not the only collaborators.

How do I deal with conflicts?
Merge conflicts can happen when you are about to push your commit, however git is not able to merge you commit into the remote, probably because another collaborator was also working on the same file.
