Learn to list the history of a specific file.
History of a specific file
The git log command normally lists the entire commit history in the repository. To see only the commits related to a specific file, add the file path to the end of the command. This filtering lets you quickly find who made changes to that file and when.
git log dosya.txt
git log --oneline -- dosya.txtPlacing a double dash (--) before the path prevents the filename from being confused with a branch name.
Renamed files and --follow
When a file is renamed, a standard git log lookup might lose the history prior to the rename. The --follow flag tells Git to follow file renames and provide the complete history. You can also add -p to inspect the patch diffs.
git log --follow yeni_ad.txt
git log -p --follow yeni_ad.txtThis allows you to review the full journey of a file even if it was moved or renamed multiple times.
Practice List commit history of a file
List the commit subjects touching ayar.json using the command git log --format="%s" -- ayar.json.
