Introduction

Git is a powerful tool that allows developers to track changes in their code, collaborate with others, and roll back changes if necessary. However, with large codebases, it can be difficult to keep track of changes and locate specific lines of code. In this article, we will discuss how to use Git diff and log with line numbers to efficiently track code changes.

Git Diff

Git diff is a command that shows the differences between two sets of code. By default, it shows the changes made to each file. However, adding the -U flag followed by a number will show the context of the changes and the number of lines before and after the changes. For example, git diff -U3 will show the changes along with three lines before and after each change.

To display line numbers in Git diff, use the -n flag followed by the number of lines to display. For example, git diff -U3 -n5 will show the changes along with five line numbers before and after each change.

Git Log

Git log is a command that shows the commit history for a repository. By default, it shows the commit hash, author, date, and message for each commit. However, adding the -p flag will show the changes made in each commit.

To display line numbers in Git log, use the -L flag followed by the line numbers and file path. For example, git log -p -L 10,15:file.txt will show the changes made to lines 10-15 in file.txt for each commit.

Conclusion

Using Git diff and log with line numbers can greatly improve code tracking and make it easier to locate specific changes in a large codebase. By adding the -U and -n flags to Git diff and the -L flag to Git log, developers can view changes along with context and line numbers. Incorporating these tips into your Git workflow can save time and increase efficiency.
