git commit -m vs. git commit -am
提问by slindsey3000
Seems easy but I just don't get it. I am in the root of my application.
看起来很简单，但我就是不明白。我在我的应用程序的根目录中。
Here is my workflow.
这是我的工作流程。
git add .
git commit -m "added a new feature some files changed"
git push heroku master
This usually works. All my changes are pushed.
这通常有效。我所有的更改都被推送了。
But sometimes I have a file that I change but when I push to Heroku the changes are not there for THAT ONE FILE... but for most of the files the changes are there...
但有时我有一个我更改的文件，但是当我推送到 Heroku 时，该文件没有更改......但对于大多数文件来说，更改都在那里......
But if I do
但如果我这样做
git add .
git commit -am "added a new feature some files changed"
git push heroku master
Everything (all changes) are pushed to Heroku
一切（所有更改）都被推送到 Heroku

From the docs:
从文档：
git commit -a automatically stage all tracked, modified files before the commitIf you think the git add stage of the workflow is too cumbersome, Git allows you to skip that part with the -a option. This basically tells Git to run git add on any file that is "tracked" - that is, any file that was in your last commit and has been modified. This allows you to do a more Subversion style workflow if you want, simply editing files and then running git commit -a when you want to snapshot everything that has been changed. You still need to run git add to start tracking new files, though, just like Subversion.
git commit -a在提交前自动暂存所有跟踪、修改的文件如果您认为工作流的 git add 阶段过于繁琐，Git 允许您使用 -a 选项跳过该部分。这基本上告诉 Git 对任何被“跟踪”的文件运行 git add - 也就是说，任何在您上次提交并已被修改的文件。如果需要，这允许您执行更多 Subversion 风格的工作流程，只需编辑文件，然后运行 git commit -a 当您想要对已更改的所有内容进行快照时。不过，您仍然需要运行 git add 来开始跟踪新文件，就像 Subversion 一样。
Using the option -amallows you to add and create a message for the commit in one command.
使用该选项-am允许您在一个命令中为提交添加和创建消息。

I would suggest, if you only changed one file then you might do something like this:
我建议，如果您只更改了一个文件，那么您可能会执行以下操作：
git add "Your_file.txt"
git commit -m "added a new feature in a file"
git push heroku master
Or if you changed multiple files then you could do something like this:
或者，如果您更改了多个文件，那么您可以执行以下操作：
git add .
git commit -m "some files changed"
git push heroku master
Similarly, you could add and commit all the files on one line with this command:
同样，您可以使用以下命令在一行中添加和提交所有文件：
git commit -am "added a new feature some files changed"
git push heroku master
