Git – git show Command-Line Utility

git show is a command-line utility in Git that allows you to view the details of a single commit or a range of commits. This is useful for troubleshooting issues and reviewing changes that have been made to your repository.

Basic Usage

To use git show, you simply need to provide it with the hash of the commit that you want to view. For example, if you want to view the details of the last commit, you can use the following command:

git show HEAD

This will display the details of the most recent commit.

Viewing Changes

One of the most useful features of git show is the ability to view the changes that were made in a particular commit. To do this, use the -p option, like so:

git show -p HEAD

This will display a diff of the changes made in the commit. You can also use git diff to view changes between two commits.

Viewing File History

Git allows you to view the changes made to a specific file over time. You can use git show to view the history of a file by providing the filename and revision hash:

git show <revision hash> <filename>

This will display the changes made to the file in the specified revision.

Conclusion

git show is a powerful command-line tool that allows you to view the details of a commit, view changes made to a file, and view the history of a file. By using these commands, you can gain a better understanding of the changes made to your repository, and troubleshoot issues more effectively.
