Basic usage of git via command line

On github.com, create repository with readme.md so that it wil be ready for cloning.

clone remote:

git clone https://github.com/atmelino/bananapi.git

cd bananapi

git command line daily workflow

change into directory of local repository

When you start working on your computer, update local repository from remote repository:

git pull

When you are done programming, send changes to remote repositoy:

git add (your filename)

git commit

(enter your comments)

git push

Python

A python program is automatically started (via crontab) when the Pi boots. How do we stop it?

1. find process ID

ps -ef | grep python

output:
UID        PID  PPID  C STIME TTY          TIME CMD

UID or USER    Username of the process's owner

PID                    Process ID number
PPID                  ID number of the process's parent process
C or CP              CPU usage and scheduling information


2. kill the according process

sudo kill 1234
