Shows a summary of the repository or a path within it.

<committish>

Summarize only the range of commits included in the <committish>.

<path>

Summarize only the range of files included in the <path>.

--dedup-by-email

Remove duplicate authors who belong to the same email address. For example,

$ git summary
...
133  TJ Holowaychuk            9.9%
115  Tj Holowaychuk            8.5%

$ git summary --dedup-by-email
...
248  TJ Holowaychuk            18.4%

--no-merges

--line
