git命令中的<pathspec>是什么？

我已经在我的应用程序中更新,修改和删除了文件,现在我已准备好提交.这是状态:

C:\G\ab\WebAdminApp>git status
On branch master
Your branch is up-to-date with 'origin/master'.

Changes not staged for commit:
  (use "git add/rm ..." to update what will be committed)
  (use "git checkout -- ..." to discard changes in working directory)

        modified:   WebAdminApp.csproj
        modified:   WebAdminApp.csproj.user
        modified:   app/admin/controllers/ContentController.ts
        deleted:    app/admin/interfaces/IEnumService.ts
        modified:   app/admin/interfaces/IHomeController.d.ts
        modified:   lib/pagedown/Markdown.Sanitizer.ts
        deleted:    lib/typings/global.ts
        modified:   package.json
        modified:   ../abilitest-admin.v12.suo

Untracked files:
  (use "git add ..." to include in what will be committed)

        app/interfaces/IEnumService.d.ts
        app/interfaces/IUtilityService.d.ts
        ../npm-debug.log

没有更改添加到提交(使用"git add"和/或"git commit -a")

当我进入:

git add . 

它给了我一条信息:

C:\G\ab\WebAdminApp>git add .
warning: You ran 'git add' with neither '-A (--all)' or '--ignore-removal',
whose behaviour will change in Git 2.0 with respect to paths you removed.
Paths like 'WebAdminApp/app/admin/interfaces/IEnumService.ts' that are
removed from your working tree are ignored with this version of Git.

* 'git add --ignore-removal ', which is the current default,
  ignores paths you removed from your working tree.

* 'git add --all ' will let you also record the removals.

我希望我在本地PC上所做的一切都得到提交,然后我希望GITHUB上的主人能够反映这一点.

有人可以解释它是什么意思 我现在应该输入什么,以便可以使用git提交来提交所有更改？对不起,我不清楚.是目录还是？
