What is the syntax for using git revert commit?

git revert commit is an important command to understand when working with version control systems such as Git. It allows you to turn back the clock on a repository to a prior commit, which can be useful in retrieving lost or deleted files and undoing miscellaneous changes that weren't supposed to happen. This article will discuss the syntax for using Git Revert.

The basic syntax for using Git Revert is:

git revert

The "commit_hash" is an alphanumeric string that references the commit you want to revert. It can typically be found by running the git log command, which displays all of the commits in reverse chronological order along with their respective hashes. Once you have identified the commit hash for the version you want to revert, simply enter it after the "git revert" command and it will create a new commit with all changes from the specified version reverted.

If for some reason you don't know what commit hash you need (e.g., if the version was committed several weeks ago and isn't down in your git log), there are other parameters you can use in combination with git revert that make it easier to identify specific versions, such as:

* --no-edit: This option allows you to skip over any editing steps and goes right back to specified commit without making additional changes beforehand.

* -n/--no-commit: This option tells Git not to create a new commit with all of the reverted changes, but rather, just undoing all of those changes in place in your current working directory.

* -m : This parameter tells Git which parent number (starting at 1) of a merge commit should be used when reverting changes back to that commit, which is helpful if working within branches that have merged together previously.
