To find the commit that introduced a specific line in a file, you can use the git blame command. This command shows information about the last modification for each line in a file, including the commit hash, author, and date.
The basic usage is:
git blame <file_name>
If you want to find the specific commit that introduced a certain line number, you can use:
git blame -L <line_number>,<line_number> <file_name>
Where <line_number> is the line number you're interested in.
Additionally, if you want to see the history of changes for a particular line, you can use the following command:
git log -L <start_line>,<end_line>:<file_name>
This will show you the commit history for the specified line range in the file.
Remember to replace <file_name> with the actual name of your file, and adjust <line_number> or <start_line>,<end_line> depending on your needs.
