blame

The git blame command is used to display the author information and commit details for each line of a file. This is useful for identifying who made specific changes and when those changes were made.

Detailed Explanation

  1. Basic Usage: git blame shows the commit hash, author, date, and the line number for each line in the file. This helps in tracking the history of changes line by line.

  2. Options:

    • -L <start>,<end>: Limits the output to the specified line range.

    • -e: Shows the email address of the author instead of the name.

    • -w: Ignores whitespace changes when assigning blame.

  3. Use Cases:

    • Identifying the author of a specific line of code.

    • Understanding the history of changes for a particular section of a file.

    • Debugging and code reviews to trace the origin of a bug or feature.

Examples

  1. Basic Blame:

    git blame Writerside/topics/Git-Blame.md

    This command shows the commit history for each line in the Writerside/topics/Git-Blame.md file.

  2. Blame with Line Range:

    git blame -L 1,10 Writerside/topics/Git-Blame.md

    This command shows the commit history for lines 1 to 10 in the Writerside/topics/Git-Blame.md file.
