<code>core.whitespace</code> instructs git to flag certain whitespace problems:

<ul>
<li><code>trailing-space</code> warns about whitespace at the end of a line or at the end of a file</li>
<li><code>space-before-tab</code> warns when there is a space before a tab used for indentation</li>
</ul>

<code>apply.whitespace</code> is used when applying a patch. It checks for whitespace errors (the ones listed above, in <code>core.whitespace</code>) and applies the patch after attempting to fix them (i.e., remove them).

These options go in <code>~/.gitconfig</code> -- that is, a <code>.gitconfig</code> file at the root of your user's home directory (typically <code>/home/user/.gitconfig</code> on Linux, <code>/Users/user/.gitconfig</code> on Mac OS X, and I don't know where on Windows but I suppose somewhere in <code>C:\Documents and Settings\user</code>).

To trim trailing whitespace on all files in the current directory, use: 

<pre><code>sed -i 's/[[:space:]]*$//' *
</code></pre>

To warn about future whitespace errors (both trailing spaces and spaces before tabs), and to fix whitespace errors in patches, add the following code to your <code>gitconfig</code> file:

<pre><code>[core]
 whitespace = trailing-space,space-before-tab
[apply]
 whitespace = fix
</code></pre>

I've accidentally put some whitespace in <a href="http://github.com/josh-brown/euler-python/commit/5eed0c8874141b87deae35de57589cd38e03dfaa" rel="noreferrer">my initial commit</a> - it shows up red in <code>git diff --color</code>. What's the best way to get rid of the existing whitespace and how can I avoid this happening again?

I am not necessarily looking for a built-in git command. Any external program available for free on Ubuntu would also be welcome.

git - trim whitespace

Windows

Ubuntu

Linux

我不小心在中放了一些空格--它在git diff --color中显示为红色。摆脱现有空格的最好方法是什么?我如何避免这种情况再次发生？我不一定要找一个内置的git命令。在Ubuntu上免费提供的任何外部程序也将受到欢迎。
