This is a follow-up to my other post on contributing to a project on Git. Whereas the other post dealt with pulling, commiting, and pushing, this post covers reverting to a previous version.
Viewing a Previous Version
View the previous version of a specific file.
git show HEAD~1:path/to/file
Or view all the files in the second (or n-th) commit back in time.
git show HEAD~2
You can use
git log to see all of the commits. You can refer to specific commits using the hash value in the log using the following formula,
git show <HASH>:path/to/file
Or you can use a relative “path” back in the commit history using the
git show "<HASH>~n":path/to/file
Viewing the Difference Between Two Versions
You can view the difference between the current version and the previous version using the
git diff path/to/file
You may also compare the current version to an arbitrary version in the commit history using the commit hash
git diff <HASH> path/to/file
Reverting to a Previous Version
Once you’re happy that you’ve found the version that you’d like to rever to, then you can revert to that version using the
git checkout <HASH> path/to/file
Alternatively, you can use the
~n pattern, with the commit hash value, or the
