From source file:bb.io.TarUtil.java

/**
* May be used either to archive to or extract from a TAR file.
* The action to perform and all of its specifications are embedded as command line switches in args.
* <p>/*from   w  w w  .ja va2s . co  m*/
* If archiving,
* the source path(s) to be archived (which can be either normal files or directories)
* are specified as the (key/value) command line switch <code>-pathsToArchive <i>commaSeparatedListOfPaths</i></code>.
* The target TAR archive file is the (key/value) command line switch <code>-tarFile <i>insertPathHere</i></code>.
* The following optional switches may also be supplied:
* <ol>
*  <li><code>-appendBackup</code> appends <code>_backup</code> to the TAR file's name</li>
*  <li><code>-appendTimeStamp</code> appends <code>_</code> followed by a timestamp to the TAR file's name</li>
*  <li><code>-appendExtension</code> appends <code>.tar</code> to the TAR file's name</li>
*  <li><code>-appendAll</code> is equivalent to supplying all the above append options</li>
*  <li>
*      <code>-filter <i>fullyQualifiedClassName</i></code>
*      specifies the name of a FileFilter which limits what gets archived.
*      Since this FileFilter class will be instantiated by a call to Class.forName,
*      it must have a no-arg constructor.
*  </li>
* </ol>
* For example, here is a complete command line that archives just the class files found under two different class directories:
* <pre><code>
   java  bb.io.TarUtil  -tarFile ../log/test.tar  -pathsToArchive ../class1,../class2  -filter bb.io.filefilter.ClassFilter
* </code></pre>
* <p>
* If extracting,
* the target directory to extract into is always specified as the command line switch <code>-directoryExtraction <i>insertPathHere</i></code>.
* The source TAR archive file is the same <code>-tarFile</code> command line switch mentioned before.
* An optional switch <code>-overwrite <i>true/false</i></code> may also be supplied
* to control if overwriting of existing normal files is allowed or not.
* By default overwriting is not allowed (an Exception will be thrown if extraction needs to overwrite an existing file).
* For example, here is a complete command line that extracts a TAR file to a specific directory, overwriting any existing files:
* <pre><code>
   java  bb.io.TarUtil  -tarFile ../log/test.tar  -directoryExtraction ../log/tarExtractOutput  -overwrite true
* </code></pre>
* <p>
* Optional GZIP compression/decompression may also be done when archiving/extracting a TAR file.
* Normally, the value for the <code>-tarFile</code> switch must be a path
* which ends in a ".tar" (case insensitive) extension.
* However, this program will also accept either ".tar.gz" or ".tgz" extensions,
* in which case it will automatically perform GZIP compression/decompression on the TAR file.
* <p>
* Note that the switches may appear in any order on the command line.
* <p>
* If this method is this Java process's entry point (i.e. first <code>main</code> method),
* then its final action is a call to {@link System#exit System.exit}, which means that <i>this method never returns</i>;
* its exit code is 0 if it executes normally, 1 if it throws a Throwable (which will be caught and logged).
* Otherwise, this method returns and leaves the JVM running.
