Let’s Git Started: do your job… 19.05.2018 Let’s Git Started: do your job… Do any modification to the content of the files. Get the update of the status of the repository $ git status Visualize the differences in the terminal. Visualize the differences in a GUI client $ git diff $ gitk ; git gui ; gitx (for MAC)

Some hints how to use GIT for your code 19.05.2018 Some hints how to use GIT for your code Commit often. Use appropriate commit messages. Do not rename the file names manually (use git mv) New files are not automatically indexed, must be added. Careful with git add . Rather choose the files: git add file1 Write a .gitignore file or use git ignore for files that you never want to commit (e.g. big datasets)
