Question

对于git中的某些子命令，如果我没有指定任何参数，我会得到一个方便的＆＃34;用法＆＃34;该命令的输出。例如：

$ git blame
usage: git blame [options] [rev-opts] [rev] [--] file

    [rev-opts] are documented in git-rev-list(1)

    --incremental         Show blame entries as we find them, incrementally
    -b                    Show blank SHA-1 for boundary commits (Default: off)
    --root                Do not treat root commits as boundaries (Default: off)
    --show-stats          Show work cost statistics
    --score-debug         Show output score for blame entries
    -f, --show-name       Show original filename (Default: auto)
    -n, --show-number     Show original linenumber (Default: off)
    -p, --porcelain       Show in a format designed for machine consumption
    --line-porcelain      Show porcelain format with per-line commit information
    -c                    Use the same output mode as git-annotate (Default: off)
    -t                    Show raw timestamp (Default: off)
    -l                    Show long commit SHA1 (Default: off)
    -s                    Suppress author name and timestamp (Default: off)
    -e, --show-email      Show author email instead of name (Default: off)
    -w                    Ignore whitespace differences
    --minimal             Spend extra cycles to find better match
    -S <file>             Use revisions from <file> instead of calling git-rev-list
    --contents <file>     Use <file>'s contents as the final image
    -C[<score>]           Find line copies within and across files
    -M[<score>]           Find line movements within and across files
    -L <n,m>              Process only line range n,m, counting from 1
    --abbrev[=<n>]        use <n> digits to display SHA-1s

但是，某些子命令实际上在没有传递参数时执行操作，例如git log。我已查看了git help的文档，但我没有看到简单显示“使用情况”的方法。用于命令而不是拉起我的Web浏览器。有谁知道我如何强制子命令将其使用信息显示到git blame这样的命令行？

我在Windows上使用msysgit 1.9.2。提前谢谢。

使用git add -h代替git add --help。

[:~] $ git add -h
usage: git add [options] [--] <pathspec>...

    -n, --dry-run         dry run
    -v, --verbose         be verbose

    -i, --interactive     interactive picking
    -p, --patch           select hunks interactively
    -e, --edit            edit current diff and apply
    -f, --force           allow adding otherwise ignored files
    -u, --update          update tracked files
    -N, --intent-to-add   record only the fact that the path will be added later
    -A, --all             add changes from all tracked and untracked files
    --ignore-removal      ignore paths removed in the working tree (same as --no-all)
    --refresh             don't add, only refresh the index
    --ignore-errors       just skip files which cannot be added because of errors
    --ignore-missing      check if - even missing - files are ignored in dry run

如何为任何命令制作git输出用法？
