Combine log options to produce a custom history report.
Combine Advanced Log Options
You can combine graph, custom format, and date filters to inspect Git history in greater detail. --graph displays branching relationships, while --format organizes output fields. --since selects only commits after the specified date.
git log --graph --since="2026-01-01" --format="%h %an %s"Practice Prepare a Custom History Report
Assign a Git command to command with these features: display the branching graph, filter commits after January 1, 2026, and print the abbreviated commit hash, author name, and commit subject in that order. Separate the fields with |. Finally, print the command.
Starter code
// Özel geçmiş raporu komutunu oluştur
const command = "";
// Komutu yazdırSample solution
const command = 'git log --graph --since="2026-01-01" --format="%h | %an | %s"';
console.log(command);Expected output
git log --graph --since="2026-01-01" --format="%h | %an | %s"
Questions and answers
Review the lesson questions together with their answers. To test yourself, solve the lesson interactively.
1 Which command is suitable for a report requiring a branch graph, custom commit fields, and a date filter?
- git status --graph --since="2026-01-01"
- git log --until="2026-01-01" --oneline
- git log --format="%h %s"
- git log --graph --since="2026-01-01" --format="%h %an %s" Correct answer
Explanation: The second command uses a graph, a starting date, and a custom output format simultaneously.
2 Complete the Report Command
git log --graph --since="2026-05-01" --format="%h %s"____git log --graph --since="2026-05-01" --format="%h %s"--since="2026-05-01"Explanation: The report should display only commits after May 1, 2026. Therefore, you must specify the starting date with --since.
