diffstat 命令

常用示例

说明

diffstat reads output from `diff` (or any unified/context diff, including `git diff`, `svn diff`, `hg diff`, or a `patch` file) and produces a histogram showing insertions, deletions, and modifications per file. It is commonly used to summarize patch size and churn. By default `diffstat` reads from stdin; a file argument reads from that file. Filenames in the header lines drive grouping; the `-p` option strips leading path components the same way as `patch -p`.

参数

-C

Strip ANSI color escape sequences before parsing. Useful with colordiff output.

-c

Show concise output with a single histogram code per file: `+` (insert), `-` (delete), `!` (modify).

-D _dir_

Directory of result files to compute unchanged line counts.

-f _format_

Filename format: 0=path, 1=name, 2=auto, 3=dir, 4=count.

-l

List filenames only.

-m

Merge insert/delete counts from each chunk to approximate modified lines.

-p _num_

Strip num leading path components (like `patch -p`).

-S _dir_

Directory containing original files (before applying diff).

-t

Output as a comma-separated table.

-u

Assume patch was created with old and new files swapped.

-w _width_

Set output width (histogram is never shorter than 10 columns).
