I read that Git mainly adds information about the repository's history, trying to remember every change made, but that there are also commands that make irreversible changes.
What are the commands that I should really pay attention to and avoid using wrongly because there is no turning back?

There are three commands with similar names: git reset , git restore and git revert .
The git reset HEAD~2 command moves the current branch backward by two commits, effectively removing the two snapshots we just created from the project history. Remember that this kind of reset should only be used on unpublished commits.

We can also use it for checking out files and commits. There are some steps you need to follow for successfully switching between branches:

There are two kinds of "destructive" here -- commands that are destructive to your git history and commands that discard changes in your working copy.
Commands that discard work tree changes:
git resetgit checkoutAs others have mentioned, the combination of the reflog and the fact that git objects don't immediately get discarded (unless you turn on automatic cleanup) means that you can usually undo operations like git reset/rebase/merge.
These commands, though, actually discard git objects, eliminating the ability to undo:
git gc (by default, this prunes unreachable objects that are at least 2 weeks old)
