What git command do you need to use to know who changed certain lines in a specific file?
To determine who changed certain lines in a specific file, you can use the
git blame command. The
git blame command displays the commit and author information for each line of a file, showing who made the last modification to that line and in which commit.
Here’s the Git command to use
git blame <file-path>
<file-path> with the path to the specific file you want to analyze. For example:
git blame myfile.txt
Running this command will display an output that looks something like this:
^1a2b3c4d (John Doe 2023-07-20 13:30:00 +0000 1) First line of the file
^5e6f7g8h (Alice Smith 2023-07-21 08:45:00 +0000 2) Second line of the file
^9i0j1k2l (John Doe 2023-07-21 14:10:00 +0000 3) Third line of the file
The output shows the commit hash, author name, date, and the line number for each line of the file. The caret symbol
^ before the commit hash indicates that the line is part of the specified commit.
git blame, you can track changes made to specific lines in a file and identify the authors responsible for those changes. This can be helpful for understanding the history of a file, tracing the origin of specific code changes, and collaborating effectively with other developers.
