============ |
|
|
|
NAME |
|
---- |
|
git-blame - Show what revision and author last modified each line of a file |
|
|
|
SYNOPSIS |
|
-------- |
|
'git-blame' [-c] [-l] [-t] [-f] [-n] [-p] [-S <revs-file>] [--] <file> [<rev>] |
|
|
|
DESCRIPTION |
|
----------- |
|
|
|
Annotates each line in the given file with information from the revision which |
|
last modified the line. Optionally, start annotating from the given revision. |
|
|
|
This report doesn't tell you anything about lines which have been deleted or |
|
replaced; you need to use a tool such as gitlink:git-diff[1] or the "pickaxe" |
|
interface briefly mentioned in the following paragraph. |
|
|
|
Apart from supporting file annotation, git also supports searching the |
|
development history for when a code snippet occured in a change. This makes it |
|
possible to track when a code snippet was added to a file, moved or copied |
|
between files, and eventually deleted or replaced. It works by searching for |
|
a text string in the diff. A small example: |
|
|
|
----------------------------------------------------------------------------- |
|
$ git log --pretty=oneline -S'blame_usage' |
|
5040f17eba15504bad66b14a645bddd9b015ebb7 blame -S <ancestry-file> |
|
ea4c7f9bf69e781dd0cd88d2bccb2bf5cc15c9a7 git-blame: Make the output |
|
----------------------------------------------------------------------------- |
|
|
|
OPTIONS |
|
------- |
|
-c, --compatibility:: |
|
Use the same output mode as gitlink:git-annotate[1] (Default: off). |
|
|
|
-l, --long:: |
|
Show long rev (Default: off). |
|
|
|
-t, --time:: |
|
Show raw timestamp (Default: off). |
|
|
|
-S, --rev-file <revs-file>:: |
|
Use revs from revs-file instead of calling gitlink:git-rev-list[1]. |
|
|
|
-f, --show-name:: |
|
Show filename in the original commit. By default |
|
filename is shown if there is any line that came from a |
|
file with different name, due to rename detection. |
|
|
|
-n, --show-number:: |
|
Show line number in the original commit (Default: off). |
|
|
|
-p, --porcelain:: |
|
Show in a format designed for machine consumption. |
|
|
|
-h, --help:: |
|
Show help message. |
|
|
|
|
|
THE PORCELAIN FORMAT |
|
-------------------- |
|
|
|
In this format, each line is output after a header; the |
|
header at the minumum has the first line which has: |
|
|
|
- 40-byte SHA-1 of the commit the line is attributed to; |
|
- the line number of the line in the original file; |
|
- the line number of the line in the final file; |
|
- on a line that starts a group of line from a different |
|
commit than the previous one, the number of lines in this |
|
group. On subsequent lines this field is absent. |
|
|
|
This header line is followed by the following information |
|
at least once for each commit: |
|
|
|
- author name ("author"), email ("author-mail"), time |
|
("author-time"), and timezone ("author-tz"); similarly |
|
for committer. |
|
- filename in the commit the line is attributed to. |
|
- the first line of the commit log message ("summary"). |
|
|
|
The contents of the actual line is output after the above |
|
header, prefixed by a TAB. This is to allow adding more |
|
header elements later. |
