Rewriting History – Changing the already existing commits

• Refer Here for rewriting history

Changing latest commit message

• We have created a commit
  
• Commit message has a typo
• we need to change the commit message
  

Changing the older commit message

• We have the following commits
  
• We need to change the commit message of 594526a to “Added 4.txt”
• we need to rewrite from one position behind head HEAD~1
  
• When using interactive rebase use HEAD~1+1
  
• In this we need to reword since we need to change the commit message.
  

Other scenarios

• Refer classroom video for
  • deleting commits
  • combining commits

Git reflog

• Refer Here for official docs
• Git reflog is like a permanent log of local git repo
• Now using reflogs we can undo certain stuff
• Exercise:
  • Create 5 commits assuming 5 is latest commit
  • Delete commit 4 and try to recover using reflog.
• Try now
