INFORMATION_SCHEMA is your friend. Even though it’s not a base table and a view (no actual data files exist for views) it contains useful information about your mysql database; including create_time. See full documentation here.

To show deleted files:

“git ls-files -d”

To restore the deleted files use:

“git ls-files -d | xargs git checkout”

View your log:

“git log”

Reset to a previous head

"git reset --hard HEAD~1" (The HEAD~1 means the commit before head.)

"git reset --hard <sha1-commit-id>
