Exercise - Creating Commits

Tips

  • git add <file/directory> Before a commit, changes must be registered with add in the staging area (also called the index).
  • The directory name . (which stands for current directory) can also be specified. The command is then applied to all files in the current directory and also subdirectories.
  • git commit -m 'My two cents' Creates a commit with all changes registered in the staging area.
  • git commit -a Registers all changes to files already versioned in Git in the staging area, so you can save the separate add call.
  • The options -a and -m can also be combined: git commit -am "Comment"
  • git log --follow -- <file-name> Shows the history of a file, even across renames.

Setup

In the repo directory, a Git project is waiting to be edited.

Step 0 - START 

$ cd repo


Step 1 - Commit - with Staging

Start in directory git-uebungen/aufgaben/<unknown>.

Edit the file hallo-welt, add it to the index with git add (staging) and create a commit with these changes.

Step 2 - Commit - automatic staging

Start in directory git-uebungen/aufgaben/<unknown>.

Edit the file hallo-welt again and create another commit, but this time with -a.

Step 3 - Commit - new file

Start in directory git-uebungen/aufgaben/<unknown>.

Create new-world and confirm it with a commit.

Step 4 - Commit - delete file

Start in directory git-uebungen/aufgaben/<unknown>.

Delete hallo-welt and confirm this with a commit.

Step 5 - ⭐ Add - recursively add files

Start in directory git-uebungen/aufgaben/<unknown>.

Create a file superneu and a directory sub with a file auchneu, add both with one add call and then create a commit.

Step 6 - ⭐ Commit - move/rename file

Start in directory git-uebungen/aufgaben/<unknown>.

Rename the file hello-world to renamed-world and confirm this with a commit.

Step 7 - ⭐ Rename detection

Start in directory git-uebungen/aufgaben/<unknown>.

Rename the file datei1 to datei2 with git mv. Make sure that the Rename Detection does not recognize this.

repo $ cd ..
