Summary - Advanced log

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"

Exercise 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.

Show example solution

const command = 'git log --graph --since="2026-01-01" --format="%h | %an | %s"';
console.log(command);

Test yourself

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"
Show answer

git log --graph --since="2026-01-01" --format="%h %an %s" — The second command uses a graph, a starting date, and a custom output format simultaneously.
