When using Git for version control, it is very important to know the commit history of the project. The git logcommand is a powerful and flexible tool that can help us view the commit history and extract the information we need. This blog will introduce in detail how to combine parameters such as author, time, file name, directory name and key string to filter and locate the required commit history.
1. Filter by author
Use --authorthe options to filter the commit history by committer's name or email address. Here is an example command using this option:
git log --author=<作者名>
For example, if you only want to view the history of commits whose author is "John Doe", you can run the following command:
git log --author="John Doe"
2. Filter by time
You can use --sincethe and --untiloptions to set the time range of the query in order to filter the relevant commit history. The following are example commands using these options:
git log --since=<起始日期> --until=<结束日期>
Wherein, the start date and end date can be a specific date (such as "2022-01-01") or a time difference relative to the current date (such as "2 weeks ago"). By setting an appropriate time range, you can easily filter the commit history for a specific date.
3. Filter by file name and directory name
If you only want to see the commit history of a specific file or directory, you can use -- <文件路径>the option. Here is an example command using this option:
git log -- <文件路径>
For example, if you want to view all the commit history under the folder "src", you can run the following command:
git log -- src/
This will only show the history of commits related to the specified file path.
4. Filter by key string
git logIt also supports filtering the submission history based on keywords in the submission information. You can use --grepoptions and specify keywords to search for. Here is an example command using this option:
git log --grep=<关键字>
For example, if you want to find the history of commits containing the keyword "bug fix", you can run the following command:
git log --grep="bug fix"
This will only show the history of commits that contain the specified keywords.
5. Combine multiple filter conditions
By combining multiple filters, you can further extract exactly the commit history you want. Here is an example command that demonstrates how to use multiple filtering options:
git log --author="John Doe" --since="2022-01-01" -- <文件路径>
This command will display the author as "John Doe", the commit date in 2022 and the history of commits relative to the specified path.
With judicious use git logof filtering options, you can get exactly the commit history you need to better understand the evolution of your project. Hope this blog is helpful to you! If you have other questions, feel free to continue asking.
