git annotate [options] file [revision]
Annotates each line in the given file with information from the commit
which introduced the line. Optionally annotates from a given revision.
The only difference between this command and git-blame(1) is that they
use slightly different output formats, and this command exists only for
backward compatibility to support existing scripts, and provide a more
familiar command name for people coming from other SCM systems.
Show blank SHA-1 for boundary commits. This can also be controlled
via the blame.blankboundary config option.
Do not treat root commits as boundaries. This can also be
controlled via the blame.showRoot config option.
Include additional statistics at the end of blame output.
-L <start>,<end>, -L :<funcname>
Annotate only the given line range. May be specified multiple
times. Overlapping ranges are allowed.
<start> and <end> are optional. "-L <start>" or "-L <start>," spans
from <start> to end of file. "-L ,<end>" spans from start of file
<start> and <end> can take one of these forms:
If <start> or <end> is a number, it specifies an absolute line
number (lines count from 1).
This form will use the first line matching the given POSIX
regex. If <start> is a regex, it will search from the end of
the previous -L range, if any, otherwise from the start of
file. If <start> is "^/regex/", it will search from the start
of file. If <end> is a regex, it will search starting at the
line given by <start>.
o +offset or -offset
This is only valid for <end> and will specify a number of lines
before or after the line given by <start>.
If ":<funcname>" is given in place of <start> and <end>, it is a
regular expression that denotes the range from the first funcname
Use revisions from revs-file instead of calling git-rev-list(1).
Walk history forward instead of backward. Instead of showing the
revision in which a line appeared, this shows the last revision in
which a line has existed. This requires a range of revision like
START..END where the path to blame exists in START.

Specifies the encoding used to output author names and commit
summaries. Setting it to none makes blame output unconverted data.
For more information see the discussion about encoding in the git-
log(1) manual page.
When <rev> is not specified, the command annotates the changes
starting backwards from the working tree copy. This flag makes the
command pretend as if the working tree copy has the contents of the
named file (specify - to make the command read from the standard
Specifies the format used to output dates. If --date is not
provided, the value of the blame.date config variable is used. If
the blame.date config variable is also not set, the iso format is
used. For supported values, see the discussion of the --date option
Detect moved or copied lines within a file. When a commit moves or
copies a block of lines (e.g. the original file has A and then B,
and the commit changes it to B and then A), the traditional blame
algorithm notices only half of the movement and typically blames
the lines that were moved up (i.e. B) to the parent and assigns
blame to the lines that were moved down (i.e. A) to the child
commit. With this option, both groups of lines are blamed on the
parent by running extra passes of inspection.
<num> is optional but it is the lower bound on the number of
alphanumeric characters that Git must detect as moving/copying
within a file for it to associate those lines with the parent
commit. The default value is 20.
between files for it to associate those lines with the parent
commit. And the default value is 40. If there are more than one -C
options given, the <num> argument of the last -C will take effect.
