blame command shows who last modified each line of a file, along with the commit ID and date.
<path> is the file to show blame information for.
[-L <start,end>] limits the output to a specific line range. For example, -L 10,20 shows only lines 10 through 20.
For each line, the output includes:
- Commit ID - the commit that last changed the line
- Author - who made the change
- Date - when the change was made
- Line number and content - the current line text
