The git blame<\/code> command is used to examine the content of any file line by line. It helps you determine who made changes to a file and when those changes were made. This command is particularly useful for tracking down the origin of a specific change or understanding the history of a file.<\/p>\n\n\n\n

Examples<\/h2>\n\n\n\n
1. Blame a Specific File<\/h4>\n\n\n\n
To see who modified each line of a specific file, simply run:<\/p>\n\n\n\n
$ git blame example.txt<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
This will display the author, date, and commit hash for each line in example.txt<\/code>.<\/p>\n\n\n\n
2. Blame a Specific Line Range<\/h4>\n\n\n\n
If you only want to see who modified a specific range of lines in a file, you can use the -L<\/code> option:<\/p>\n\n\n\n
$ git blame -L 10,20 example.txt<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
This will display the blame information for lines 10 to 20 in example.txt<\/code>.<\/p>\n\n\n\n
3. Blame with Additional Options<\/h4>\n\n\n\n
You can also use the -c<\/code>, -w<\/code>, and -M<\/code> options to customize the output:<\/p>\n\n\n\n
    \n
  • -c<\/code>: Displays the original commit for lines that have been moved or copied.<\/li>\n\n\n\n
  • -w<\/code>: Ignores changes in whitespace.<\/li>\n\n\n\n
  • -M<\/code>: Detects lines that have been moved within a file.<\/li>\n<\/ul>\n\n\n\n
    For example, to blame a file and ignore whitespace changes:<\/p>\n\n\n\n
    $ git blame -w example.txt<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    This will display the blame information for example.txt<\/code>, ignoring any changes in whitespace.<\/p>\n","protected":false},"excerpt":{"rendered":"
