Git for Beginners: Call for Coaches
View gist:3754453

The OpenTechSchool has set up and hosted a few tech workshops and meetups here in Berlin now. Aside from the monthly Beginners Meetup and hosting the Udacity Global Meetup we hosted workshops for program beginners in Python and Javascript on our own and on the premise of CampusParty.

One thing that was extraordinary popular on CampusParty was the Workshop on Git for beginners. And we decided to do it again, this time with a closer focus on version control as a major benefit in code sharing (by using git and github) for beginners - free of charge.

So if you are interested in

Git pre-commit hook to add a new line at the end of a file and remove trailing whitespaces
View pre-commit.sh
#!/bin/sh
#
# An example hook script to verify what is about to be committed.
# Called by "git commit" with no arguments. The hook should
# exit with non-zero status after issuing an appropriate message if
# it wants to stop the commit.
#
# Usage:
# Remove the .sh file extension when you put the script in your hooks folder!
