Combine show and log options to research the history.
History inspection tools summary
With git show, you inspect the details and patch diff of a single commit. Meanwhile, git log lets you search history using --author, --since, and file filters. For renamed files, you rely on the --follow flag to keep tracking history.
git show -s HEAD
git log --author="Ece" --oneline
git log --follow -- ayar.jsonUsing these tools together lets you effortlessly trace any change across the project.
Practice Combine author and file filter
Run git log with --author="Ece", --format="%s", and -- modul_a.py to list the matching commit subject.
