What are the options available for modifying commits during an interactive rebase?

During an interactive rebase in Git, you have several options for modifying commits. Here are the main commands you can use:

pick: Use this option to keep the commit as it is. It means you want to include this commit in the rebase without any changes.
edit: This option allows you to modify the commit. Git will pause at this commit, and you can make changes to the files, stage them, and amend the commit.
squash (or s): This option combines the commit with the previous commit. It allows you to merge the changes into the previous commit and can also prompt you to edit the commit message.
fixup (or f): Similar to squash, but it combines the commit with the previous one without prompting for a new commit message. The commit message of the commit being fixed up is discarded.
drop: This option removes the commit entirely from the history. It effectively deletes the commit from the branch.
reword (or r): This option allows you to change the commit message of the commit without modifying the content of the commit itself. Git will prompt you to edit the commit message.

Example of Interactive Rebase Commands:

When you run git rebase -i HEAD~N, you might see something like this in your editor:

pick abc1234 Commit message 1
edit def5678 Commit message 2
squash ghi9101 Commit message 3
reword jkl2345 Commit message 4
drop mno6789 Commit message 5

Summary

The options available during an interactive rebase include pick, edit, squash, fixup, drop, and reword. Each option allows you to modify the commit history in different ways, such as keeping, editing, combining, or removing commits.
