Git contd..

Adding multiple changes to index area

• In Git we can deal with multiple changes at one time and add all of those changes to the staging/index area.
• Lets create two new files in folders and make changes to existing file and execute status command
• For git
  • untracked file => This was not present in the local repo and you have created a new file
  • modified => Made changes to existing files
  • If the new files are part of some folder, then git will show folder in the status but actually will track files.
• Now lets add the changes
• Now lets commit the changes to the local repository
• Now lets create two more files in src app.py and requirements.txt
• Now make changes in existing file (Readme.md) and execute git status
• Now if we want to add only modified files not untracked files to index/staging area
• Now lets make some more changes in main.py of src
• Now lets navigate to test folder
  • here git add . will not workout as changes are not in test folder, lets add all the files to the staging area using git add -A
• Lets do a change by deleting a file src/app.py
• Now lets add these changes to repo via staging area
• Now execute git log
• Now lets make changes in 3 files and add that to staging area
• Now lets try to reset the change in test/main.py and src/main.py
• Now if we want to remove the changes in test/main.py and src/main.py in the working tree as well
• If you want to remove all the changes in index area and working tree with one command
• Now lets create a new set of changes with untracked files, modified files
• Now to remove the untracked files
• Exercise: Findout the difference b/w git reset –hard and git reset –soft
• Git Log Variants
  • Display All commits
  • View n most recent commits git log -n
  • Filter commits by author
  • Filter commits by date

  git log --before <date>
  git log --after <date>
  

  
  • Viewing all the changes done in each commit git log -p
  • To view summary of each commit git log --stat
