<div class="block">General file manipulation utilities.
<p>
Facilities are provided in the following areas:
<ul>
<li>writing to a file
<li>reading from a file
<li>make a directory including parent directories
<li>copying files and directories
<li>deleting files and directories
<li>converting to and from a URL
<li>listing files and directories by filter and extension
<li>comparing file content
<li>file last changed date
<li>calculating a checksum
</ul>
<p>
Note that a specific charset should be specified whenever possible.
Relying on the platform default means that the code is Locale-dependent.
Only use the default if the files are known to always use the platform default.

that for you.

An example: If you want to search through all directories called
"temp" you pass in <code>FileFilterUtils.NameFileFilter("temp")</code>

tree but ignoring the directories generated CVS. You can simply pass

<div class="block">Returns an Iterator for the lines in a <code>File</code>.
<p>
This method opens an <code>InputStream</code> for the file.
When you have finished with the iterator you should close the stream
to free internal resources. This can be done by calling the
<a href="../../../../org/apache/commons/io/LineIterator.html#close--"><code>LineIterator.close()</code></a> or
<a href="../../../../org/apache/commons/io/LineIterator.html#closeQuietly-org.apache.commons.io.LineIterator-"><code>LineIterator.closeQuietly(LineIterator)</code></a> method.
<p>
The recommended usage pattern is:
<pre>
LineIterator it = FileUtils.lineIterator(file, "UTF-8");
try {
while (it.hasNext()) {
String line = it.nextLine();
/// do something with line
}
} finally {
LineIterator.closeQuietly(iterator);
}
</pre>
<p>
If an exception occurs during the creation of the iterator, the
underlying stream is closed.</div>
