How do I delete a file from a Git repository?

Deleting a file from a Git repository is a common task when you want to remove unwanted or outdated files from your project history. But how exactly do you do it properly so that the file is removed from both your local folder and the Git repo?

Here’s a simple step-by-step explanation:

Use git rm command:

 The easiest and most standard way to delete a file tracked by Git is to use the command:

  git rm filename

 This command removes the file from your working directory and stages the deletion for the next commit.

Commit the change:

 After staging the removal, you need to commit it to finalize the deletion in the Git history:

  git commit -m "Remove filename from repository"

Push the changes to remote (if using remote repositories like GitHub, GitLab):

  git push origin branch-name

 This updates the remote repository, so the file is deleted there too.

What if the file is untracked?

• If the file is not yet tracked by Git (never committed), you can simply delete it from your file system without using Git commands.
  
• Removing a file from Git history entirely
  
• If you want to erase a file completely from Git history (like for sensitive data), you’ll need advanced tools like git filter-branch or BFG Repo-Cleaner.
  

Summary:

• git rm filename deletes and stages removal
  
• Commit the change with a meaningful message
  
• Push to remote if needed
  
• For untracked files, manual deletion works
  
• Use special tools to remove files from Git history entirely
